  • log in to web-app through less secure website [on hold]

    - by martijnve
    We are worried about the security of our website containing the login-button to our saas-application. Security measures put in place for our application won't do us much good if the website is hacked. The login button could be redirected to some malicious copy of our app. The product website is maintained by people outside the dev team. Those people are not too knowledgable concerning security. We (dev-team) could mantain the website ourselves but that would be a large burden on our small team. How is this usually handled?

  • Share Your Top 30 Visited Domains with Visitation Cloud for Firefox

    - by Asian Angel
    Curious about the domains that you visit most or perhaps you want a way to share that information on a social website? Now you can see and share the 30 most visited domains in your browser’s history with the Visitation Cloud extension. Accessing Visitation Cloud As soon as you install the extension you can get started using it. Depending on how your browser’s UI is set up there are three methods for accessing Visitation Cloud: a “Visitation Cloud Button” inserted at the end of your “Bookmarks Toolbar”, a menu listing in the “Tools Menu”, and a “Toolbar Button” (not shown here). Visitation Cloud in Action As soon as you activate Visitation Cloud a new window will appear with your top domains displayed in a cloud format. Keep in mind that this is more than just a static image…each listing is actually a clickable link. Clicking on any of the listings will open that domain in a new tab or window depending on your particular browser settings. If you feel that you have a great set of links and want to share it with your friends then that is easy to do. Right click anywhere within the Visitation Cloud Window and select “Save as…”. The “cloud image” can be saved in “.png, .jpg, or Scalable Vector Graphics (.svg)” format. For our example we chose the “.svg format”. Perhaps you love the set of links but not the layout…right click and select “Randomize” to change how the cloud looks. Here is our cloud after being “Randomized”. Things definitely got moved around… Accessing the Visitation Cloud Image in other Browsers Once you have your “cloud image” saved you can share it with friends or save it for your own future use in other browsers. Here is our “cloud image” open in Opera Browser with link opening in progress. The same “cloud image” open in Google Chrome. Very nice… Conclusion While this may not be something that everyone will use Visitation Cloud does make for a rather unique, interesting, & fun way to access and share your most visited domains.

  • Good quality Secure Software Development Training [closed]

    - by Patrick
    Just had my annual appraisal and found out my company is willing to pay for training and exams etc! Woohoo (they kept that one quiet). I'm interested in doing a course on secure development techniques. Has anyone got any suggestions for good quality distance learning courses in secure development (I could probably get a couple of days off to attend a conference/ course if required)? We're mostly an MS .Net house but I have no particular allegiance to MS or any other programming language (though, obviously, C++ is the best language in the world). I have 12 years development experience working in (what are now) PCI:DSS environments, including designing and developing a key management system and I have some knowledge of basic attacks (XSS, injection etc). I would prefer a hard course I struggle with to a basic course I learn 3 things from (but hopefully get something right at my level). A quick google found these two course which look good: http://www.sans.org/course/secure-coding-net-developing-defensible-applications https://www.isc2.org/csslpedu/default.aspx I don't really know how to choose between them, and finding other courses isn't going to make that job any easier, so I thought I'd ask those who know. EDIT : Hmm, care to share the reason for your down vote, will help me learn how to use the site better...

  • Anyone have BlazeDS working with WebLogic Security (j_security_check) ??

    - by Brian
    I'm working on a Flex implementation (currently using SDK 3.5) on WebLogic 10.3 (11G.) We originally used Glassfish v2.1.1 with zero issues (there was an active directory group lookup bug but it did not hinder our progress.) Since transitioning to WebLogic we have an issue where the flexsession is invalidated after logging in using j_security_check: [BlazeDS]Unexpected error encountered in Message Broker servlet flex.messaging.LocalizedException: The FlexSession is invalid. at flex.messaging.FlexSession.checkValid(FlexSession.java:943) at flex.messaging.FlexSession.getUserPrincipal(FlexSession.java:254) at flex.messaging.HttpFlexSession.getUserPrincipal(HttpFlexSession.java:286) at flex.messaging.MessageBrokerServlet.service(MessageBrokerServlet.java:296) at javax.servlet.http.HttpServlet.service(HttpServlet.java:820) at weblogic.servlet.internal.StubSecurityHelper$ServletServiceAction.run(StubSecurityHelper.java:227) at weblogic.servlet.internal.StubSecurityHelper.invokeServlet(StubSecurityHelper.java:125) at weblogic.servlet.internal.ServletStubImpl.execute(ServletStubImpl.java:292) at weblogic.servlet.internal.ServletStubImpl.execute(ServletStubImpl.java:175) at weblogic.servlet.internal.WebAppServletContext$ServletInvocationAction.run(WebAppServletContext.java:3594) at weblogic.security.acl.internal.AuthenticatedSubject.doAs(AuthenticatedSubject.java:321) at weblogic.security.service.SecurityManager.runAs(SecurityManager.java:121) at weblogic.servlet.internal.WebAppServletContext.securedExecute(WebAppServletContext.java:2202) at weblogic.servlet.internal.WebAppServletContext.execute(WebAppServletContext.java:2108) at weblogic.servlet.internal.ServletRequestImpl.run(ServletRequestImpl.java:1432) at weblogic.work.ExecuteThread.execute(ExecuteThread.java:201) at weblogic.work.ExecuteThread.run(ExecuteThread.java:173) I've tried almost every option in services-config.xml: [security [login-command class="flex.messaging.security.WeblogicLoginCommand" server="Weblogic"/> [!-- Uncomment the correct app server [login-command class="flex.messaging.security.TomcatLoginCommand" server="JBoss"> [login-command class="flex.messaging.security.JRunLoginCommand" server="JRun"/> [login-command class="flex.messaging.security.TomcatLoginCommand" server="Tomcat"/> [login-command class="flex.messaging.security.WebSphereLoginCommand" server="WebSphere"/> --> [/security> I've even completely removed this section with no luck. The login functions correctly from a non-BlazeDS perspective. It authenticates the user correctly. Without authentication, BlazeDS works fine (no errors for any remote calls.) Together its a big ball of fail (invalid flexsession every time.) Has anyone got this working? Any tips?

  • Umbraco Permissions Script - Secure Version

    - by Vizioz Limited
    Back in May I blogged about how to set Permissions for Umbraco using SetACL to set the appropriate directory permissions based on the installation recommendations.Recently I have been working on a site for a client who wanted every security item to be locked down as tightly as possible. And so I modified the script based on the Umbraco security best practices, I thought I'd share it with everyone, if I have missed anything, or if anyone has any suggestions on how to improve this, please let me know :)Please refer to my previous post regarding the SetAcl command line application that you will need.I suggest you save the following into a batch file called: umbPermSecure.batecho offREM Script to setup the Security Permissions for an Umbraco siteREM This script will give your machine Network Service the minimum rights requiredREM for Umbraco to workREM I suggest you update this script to also remove any users who do not need REM access to the web foldersREM **** Pre-requisites ****REM You will need to download - http://setacl.sourceforge.net/REM It is assumed that you have stored SetACL in a directory called, C:\SetACL ifREM not, you will need to modify the script.REM **** Usage ****REM You need to pass in the path for the root of your Umbraco directoryREM E.g. umbPermSecure.bat C:\inetpub\umbracoroot@echo umbPermSecure.bat - Script to set Umbraco File and Directory Permissions@echo based on the Umbraco Security Best Practices Document (13th March 2009)@echo Published by Chris Houston - 19th October 2009@echo http://blog.vizioz.com@echo Adding READ only access SetACL.exe -on "%1" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\web.config" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\bin" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\umbraco" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"@echo Adding READ and EXECUTE access SetACL.exe -on "%1\app_code" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read_ex" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\usercontrols" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read_ex" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"@echo Adding READ, WRITE and MODIFY access SetACL.exe -on "%1\config" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -ace "n:%computername%\NETWORK SERVICE;p:change" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\css" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -ace "n:%computername%\NETWORK SERVICE;p:change" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\data" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -ace "n:%computername%\NETWORK SERVICE;p:change" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\masterpages" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -ace "n:%computername%\NETWORK SERVICE;p:change" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\media" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -ace "n:%computername%\NETWORK SERVICE;p:change" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\python" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -ace "n:%computername%\NETWORK SERVICE;p:change" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\scripts" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -ace "n:%computername%\NETWORK SERVICE;p:change" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\xslt" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -ace "n:%computername%\NETWORK SERVICE;p:change" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"

  • Internet Explorer Security: How to Configure Settings

    Before jumping into the steps that are needed to configure Internet Explorer's security settings, let us first take a closer look at the four separate security zones that Microsoft has established for the browser. You will be able to tweak the settings of each of these four zones when we get into the configuration part of this tutorial, so it is best that you learn what they represent first. Internet Explorer Security Zones Internet Zone This Internet Explorer security zone refers to websites that are not on your computer or are not designated to your local intranet, which we will discuss in ...

  • How I might think like a hacker so that I can anticipate security vulnerabilities in .NET or Java before a hacker hands me my hat [closed]

    - by Matthew Patrick Cashatt
    Premise I make a living developing web-based applications for all form-factors (mobile, tablet, laptop, etc). I make heavy use of SOA, and send and receive most data as JSON objects. Although most of my work is completed on the .NET or Java stacks, I am also recently delving into Node.js. This new stack has got me thinking that I know reasonably well how to secure applications using known facilities of .NET and Java, but I am woefully ignorant when it comes to best practices or, more importantly, the driving motivation behind the best practices. You see, as I gain more prominent clientele, I need to be able to assure them that their applications are secure and, in order to do that, I feel that I should learn to think like a malevolent hacker. What motivates a malevolent hacker: What is their prime mover? What is it that they are most after? Ultimately, the answer is money or notoriety I am sure, but I think it would be good to understand the nuanced motivators that lead to those ends: credit card numbers, damning information, corporate espionage, shutting down a highly visible site, etc. As an extension of question #1--but more specific--what are the things most likely to be seeked out by a hacker in almost any application? Passwords? Financial info? Profile data that will gain them access to other applications a user has joined? Let me be clear here. This is not judgement for or against the aforementioned motivations because that is not the goal of this post. I simply want to know what motivates a hacker regardless of our individual judgement. What are some heuristics followed to accomplish hacker goals? Ultimately specific processes would be great to know; however, in order to think like a hacker, I would really value your comments on the broader heuristics followed. For example: "A hacker always looks first for the low-hanging fruit such as http spoofing" or "In the absence of a CAPTCHA or other deterrent, a hacker will likely run a cracking script against a login prompt and then go from there." Possibly, "A hacker will try and attack a site via Foo (browser) first as it is known for Bar vulnerability. What are the most common hacks employed when following the common heuristics? Specifics here. Http spoofing, password cracking, SQL injection, etc. Disclaimer I am not a hacker, nor am I judging hackers (Heck--I even respect their ingenuity). I simply want to learn how I might think like a hacker so that I may begin to anticipate vulnerabilities before .NET or Java hands me a way to defend against them after the fact.

  • Are Rackspace's Cloud Servers really cloud hosting?

    - by sopppas
    I may be confused about what cloud hosting really is... I asked Rackspace how its Cloud Server (CS) 256MB/10GB compares to Slicehost's 256slice VPS, and they said it's exactly the same (only different billing and BW). I know they are the same company. So, why do they call it Cloud Server? Isn't it just a collection of VPS (virtual private servers)? For me, cloud hosting would be: if I need any additional horsepower at any given time, the cloud would automatically stack more VPS and then charge me at the end of the month for the surplus of resources. Reading Rackspace's info, it looks like it's for me to decide when to stack more CS and that its Cloud Servers don't AUTOMATICLY scale up. Am I confusing things?

  • What is New in ASP.NET 4.0 Code Access Security

    - by Xiaohong
    ASP.NET Code Access Security (CAS) is a feature that helps protect server applications on hosting multiple Web sites, ASP.NET lets you assign a configurable trust level that corresponds to a predefined set of permissions. ASP.NET has predefined ASP.NET Trust Levels and Policy Files that you can assign to applications, you also can assign custom trust level and policy files. Most web hosting companies run ASP.NET applications in Medium Trust to prevent that one website affect or harm another site etc. As .NET Framework's Code Access Security model has evolved, ASP.NET 4.0 Code Access Security also has introduced several changes and improvements. The main change in ASP.NET 4.0 CAS In ASP.NET v4.0 partial trust applications, application domain can have a default partial trust permission set as opposed to being full-trust, the permission set name is defined in the <trust /> new attribute permissionSetName that is used to initialize the application domain . By default, the PermissionSetName attribute value is "ASP.Net" which is the name of the permission set you can find in all predefined partial trust configuration files. <trust level="Something" permissionSetName="ASP.Net" /> This is ASP.NET 4.0 new CAS model. For compatibility ASP.NET 4.0 also support legacy CAS model where application domain still has full trust permission set. You can specify new legacyCasModel attribute on the <trust /> element to indicate whether the legacy CAS model is enabled. By default legacyCasModel is false which means that new 4.0 CAS model is the default. <trust level="Something" legacyCasModel="true|false" /> In .Net FX 4.0 Config directory, there are two set of predefined partial trust config files for each new CAS model and legacy CAS model, trust config files with name legacy.XYZ.config are for legacy CAS model: New CAS model: Legacy CAS model: web_hightrust.config legacy.web_hightrust.config web_mediumtrust.config legacy.web_mediumtrust.config web_lowtrust.config legacy.web_lowtrust.config web_minimaltrust.config legacy.web_minimaltrust.config   The figure below shows in ASP.NET 4.0 new CAS model what permission set to grant to code for partial trust application using predefined partial trust levels and policy files:    There also some benefits that comes with the new CAS model: You can lock down a machine by making all managed code no-execute by default (e.g. setting the MyComputer zone to have no managed execution code permissions), it should still be possible to configure ASP.NET web applications to run as either full-trust or partial trust. UNC share doesn’t require full trust with CASPOL at machine-level CAS policy. Side effect that comes with the new CAS model: processRequestInApplicationTrust attribute is deprecated  in new CAS model since application domain always has partial trust permission set in new CAS model.   In ASP.NET 4.0 legacy CAS model or ASP.NET 2.0 CAS model, even though you assign partial trust level to a application but the application domain still has full trust permission set. The figure below shows in ASP.NET 4.0 legacy CAS model (or ASP.NET 2.0 CAS model) what permission set to grant to code for partial trust application using predefined partial trust levels and policy files:     What $AppDirUrl$, $CodeGen$, $Gac$ represents: $AppDirUrl$ The application's virtual root directory. This allows permissions to be applied to code that is located in the application's bin directory. For example, if a virtual directory is mapped to C:\YourWebApp, then $AppDirUrl$ would equate to C:\YourWebApp. $CodeGen$ The directory that contains dynamically generated assemblies (for example, the result of .aspx page compiles). This can be configured on a per application basis and defaults to %windir%\Microsoft.NET\Framework\{version}\Temporary ASP.NET Files. $CodeGen$ allows permissions to be applied to dynamically generated assemblies. $Gac$ Any assembly that is installed in the computer's global assembly cache (GAC). This allows permissions to be granted to strong named assemblies loaded from the GAC by the Web application.   The new customization of CAS Policy in ASP.NET 4.0 new CAS model 1. Define which named permission set in partial trust configuration files By default the permission set that will be assigned at application domain initialization time is the named "ASP.Net" permission set found in all predefined partial trust configuration files. However ASP.NET 4.0 allows you set PermissionSetName attribute to define which named permission set in a partial trust configuration file should be the one used to initialize an application domain. Example: add "ASP.Net_2" named permission set in partial trust configuration file: <PermissionSet class="NamedPermissionSet" version="1" Name="ASP.Net_2"> <IPermission class="FileIOPermission" version="1" Read="$AppDir$" PathDiscovery="$AppDir$" /> <IPermission class="ReflectionPermission" version="1" Flags ="RestrictedMemberAccess" /> <IPermission class="SecurityPermission " version="1" Flags ="Execution, ControlThread, ControlPrincipal, RemotingConfiguration" /></PermissionSet> Then you can use "ASP.Net_2" named permission set for the application domain permission set: <trust level="Something" legacyCasModel="false" permissionSetName="ASP.Net_2" /> 2. Define a custom set of Full Trust Assemblies for an application By using the new fullTrustAssemblies element to configure a set of Full Trust Assemblies for an application, you can modify set of partial trust assemblies to full trust at the machine, site or application level. The configuration definition is shown below: <fullTrustAssemblies> <add assemblyName="MyAssembly" version="1.1.2.3" publicKey="hex_char_representation_of_key_blob" /></fullTrustAssemblies> 3. Define <CodeGroup /> policy in partial trust configuration files ASP.NET 4.0 new CAS model will retain the ability for developers to optionally define <CodeGroup />with membership conditions and assigned permission sets. The specific restriction in ASP.NET 4.0 new CAS model though will be that the results of evaluating custom policies can only result in one of two outcomes: either an assembly is granted full trust, or an assembly is granted the partial trust permission set currently associated with the running application domain. It will not be possible to use custom policies to create additional custom partial trust permission sets. When parsing the partial trust configuration file: Any assemblies that match to code groups associated with "PermissionSet='FullTrust'" will run at full trust. Any assemblies that match to code groups associated with "PermissionSet='Nothing'" will result in a PolicyError being thrown from the CLR. This is acceptable since it provides administrators with a way to do a blanket-deny of managed code followed by selectively defining policy in a <CodeGroup /> that re-adds assemblies that would be allowed to run. Any assemblies that match to code groups associated with other permissions sets will be interpreted to mean the assembly should run at the permission set of the appdomain. This means that even though syntactically a developer could define additional "flavors" of partial trust in an ASP.NET partial trust configuration file, those "flavors" will always be ignored. Example: defines full trust in <CodeGroup /> for my strong named assemblies in partial trust config files: <CodeGroup class="FirstMatchCodeGroup" version="1" PermissionSetName="Nothing"> <IMembershipCondition    class="AllMembershipCondition"    version="1" /> <CodeGroup    class="UnionCodeGroup"    version="1"    PermissionSetName="FullTrust"    Name="My_Strong_Name"    Description="This code group grants code signed full trust. "> <IMembershipCondition      class="StrongNameMembershipCondition" version="1"       PublicKeyBlob="hex_char_representation_of_key_blob" /> </CodeGroup> <CodeGroup   class="UnionCodeGroup" version="1" PermissionSetName="ASP.Net">   <IMembershipCondition class="UrlMembershipCondition" version="1" Url="$AppDirUrl$/*" /> </CodeGroup> <CodeGroup class="UnionCodeGroup" version="1" PermissionSetName="ASP.Net">   <IMembershipCondition class="UrlMembershipCondition" version="1" Url="$CodeGen$/*"   /> </CodeGroup></CodeGroup>   4. Customize CAS policy at runtime in ASP.NET 4.0 new CAS model ASP.NET 4.0 new CAS model allows to customize CAS policy at runtime by using custom HostSecurityPolicyResolver that overrides the ASP.NET code access security policy. Example: use custom host security policy resolver to resolve partial trust web application bin folder MyTrustedAssembly.dll to full trust at runtime: You can create a custom host security policy resolver and compile it to assembly MyCustomResolver.dll with strong name enabled and deploy in GAC: public class MyCustomResolver : HostSecurityPolicyResolver{ public override HostSecurityPolicyResults ResolvePolicy(Evidence evidence) { IEnumerator hostEvidence = evidence.GetHostEnumerator(); while (hostEvidence.MoveNext()) { object hostEvidenceObject = hostEvidence.Current; if (hostEvidenceObject is System.Security.Policy.Url) { string assemblyName = hostEvidenceObject.ToString(); if (assemblyName.Contains(“MyTrustedAssembly.dll”) return HostSecurityPolicyResult.FullTrust; } } //default fall-through return HostSecurityPolicyResult.DefaultPolicy; }} Because ASP.NET accesses the custom HostSecurityPolicyResolver during application domain initialization, and a custom policy resolver requires full trust, you also can add a custom policy resolver in <fullTrustAssemblies /> , or deploy in the GAC. You also need configure a custom HostSecurityPolicyResolver instance by adding the HostSecurityPolicyResolverType attribute in the <trust /> element: <trust level="Something" legacyCasModel="false" hostSecurityPolicyResolverType="MyCustomResolver, MyCustomResolver" permissionSetName="ASP.Net" />   Note: If an assembly policy define in <CodeGroup/> and also in hostSecurityPolicyResolverType, hostSecurityPolicyResolverType will win. If an assembly added in <fullTrustAssemblies/> then the assembly has full trust no matter what policy in <CodeGroup/> or in hostSecurityPolicyResolverType.   Other changes in ASP.NET 4.0 CAS Use the new transparency model introduced in .Net Framework 4.0 Change in dynamically compiled code generated assemblies by ASP.NET: In new CAS model they will be marked as security transparent level2 to use Framework 4.0 security transparent rule that means partial trust code is treated as completely Transparent and it is more strict enforcement. In legacy CAS model they will be marked as security transparent level1 to use Framework 2.0 security transparent rule for compatibility. Most of ASP.NET products runtime assemblies are also changed to be marked as security transparent level2 to switch to SecurityTransparent code by default unless SecurityCritical or SecuritySafeCritical attribute specified. You also can look at Security Changes in the .NET Framework 4 for more information about these security attributes. Support conditional APTCA If an assembly is marked with the Conditional APTCA attribute to allow partially trusted callers, and if you want to make the assembly both visible and accessible to partial-trust code in your web application, you must add a reference to the assembly in the partialTrustVisibleAssemblies section: <partialTrustVisibleAssemblies> <add assemblyName="MyAssembly" publicKey="hex_char_representation_of_key_blob" />/partialTrustVisibleAssemblies>   Most of ASP.NET products runtime assemblies are also changed to be marked as conditional APTCA to prevent use of ASP.NET APIs in partial trust environments such as Winforms or WPF UI controls hosted in Internet Explorer.   Differences between ASP.NET new CAS model and legacy CAS model: Here list some differences between ASP.NET new CAS model and legacy CAS model ASP.NET 4.0 legacy CAS model  : Asp.net partial trust appdomains have full trust permission Multiple different permission sets in a single appdomain are allowed in ASP.NET partial trust configuration files Code groups Machine CAS policy is honored processRequestInApplicationTrust attribute is still honored    New configuration setting for legacy model: <trust level="Something" legacyCASModel="true" ></trust><partialTrustVisibleAssemblies> <add assemblyName="MyAssembly" publicKey="hex_char_representation_of_key_blob" /></partialTrustVisibleAssemblies>   ASP.NET 4.0 new CAS model: ASP.NET will now run in homogeneous application domains. Only full trust or the app-domain's partial trust grant set, are allowable permission sets. It is no longer possible to define arbitrary permission sets that get assigned to different assemblies. If an application currently depends on fine-tuning the partial trust permission set using the ASP.NET partial trust configuration file, this will no longer be possible. processRequestInApplicationTrust attribute is deprecated Dynamically compiled assemblies output by ASP.NET build providers will be updated to explicitly mark assemblies as transparent. ASP.NET partial trust grant sets will be independent from any enterprise, machine, or user CAS policy levels. A simplified model for locking down web servers that only allows trusted managed web applications to run. Machine policy used to always grant full-trust to managed code (based on membership conditions) can instead be configured using the new ASP.NET 4.0 full-trust assembly configuration section. The full-trust assembly configuration section requires explicitly listing each assembly as opposed to using membership conditions. Alternatively, the membership condition(s) used in machine policy can instead be re-defined in a <CodeGroup /> within ASP.NET's partial trust configuration file to grant full-trust.   New configuration setting for new model: <trust level="Something" legacyCASModel="false" permissionSetName="ASP.Net" hostSecurityPolicyResolverType=".NET type string" ></trust><fullTrustAssemblies> <add assemblyName=”MyAssembly” version=”1.0.0.0” publicKey="hex_char_representation_of_key_blob" /></fullTrustAssemblies><partialTrustVisibleAssemblies> <add assemblyName="MyAssembly" publicKey="hex_char_representation_of_key_blob" /></partialTrustVisibleAssemblies>     Hope this post is helpful to better understand the ASP.Net 4.0 CAS.

  • Does the "security" repository provides anything not found in the "updates" repository?

    - by netvope
    For the limited number of package I looked at (e.g. apache), I found that the package version in the updates repository is always newer than or equal to the version available in the security repository (provided that they exist). This gives me the impression that all security patches posted to the security repository are also posted to the updates repository. If this is true, I can remove all <release_name>-security entries in my apt sources.list and the <release_name>-updates entries will still give me the security patches. This will speed up apt-get update quite a bit. The best documentation I can found regarding the repositories is on the community help page "Important Security Updates (raring-security)". Patches for security vulnerabilities in Ubuntu packages. They are managed by the Ubuntu Security Team and are designed to change the behavior of the package as little as possible -- in fact, the minimum required to resolve the security problem. As a result, they tend to be very low-risk to apply and all users are urged to apply security updates. "Recommended Updates (raring-updates)". Updates for serious bugs in Ubuntu packaging that do not affect the security of the system. However, it does not mention whether the updates repository also includes everything in the security repository. Can anyone confirm (or disconfirm) this?

  • WCF WS-Security and WSE Nonce Authentication

    - by Rick Strahl
    WCF makes it fairly easy to access WS-* Web Services, except when you run into a service format that it doesn't support. Even then WCF provides a huge amount of flexibility to make the service clients work, however finding the proper interfaces to make that happen is not easy to discover and for the most part undocumented unless you're lucky enough to run into a blog, forum or StackOverflow post on the matter. This is definitely true for the Password Nonce as part of the WS-Security/WSE protocol, which is not natively supported in WCF. Specifically I had a need to create a WCF message on the client that includes a WS-Security header that looks like this from their spec document:<soapenv:Header> <wsse:Security soapenv:mustUnderstand="1" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <wsse:UsernameToken wsu:Id="UsernameToken-8" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"> <wsse:Username>TeStUsErNaMe1</wsse:Username> <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText" >TeStPaSsWoRd1</wsse:Password> <wsse:Nonce EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary" >f8nUe3YupTU5ISdCy3X9Gg==</wsse:Nonce> <wsu:Created>2011-05-04T19:01:40.981Z</wsu:Created> </wsse:UsernameToken> </wsse:Security> </soapenv:Header> Specifically, the Nonce and Created keys are what WCF doesn't create or have a built in formatting for. Why is there a nonce? My first thought here was WTF? The username and password are there in clear text, what does the Nonce accomplish? The Nonce and created keys are are part of WSE Security specification and are meant to allow the server to detect and prevent replay attacks. The hashed nonce should be unique per request which the server can store and check for before running another request thus ensuring that a request is not replayed with exactly the same values. Basic ServiceUtl Import - not much Luck The first thing I did when I imported this service with a service reference was to simply import it as a Service Reference. The Add Service Reference import automatically detects that WS-Security is required and appropariately adds the WS-Security to the basicHttpBinding in the config file:<?xml version="1.0" encoding="utf-8" ?> <configuration> <system.serviceModel> <bindings> <basicHttpBinding> <binding name="RealTimeOnlineSoapBinding"> <security mode="Transport" /> </binding> <binding name="RealTimeOnlineSoapBinding1" /> </basicHttpBinding> </bindings> <client> <endpoint address="https://notarealurl.com:443/services/RealTimeOnline" binding="basicHttpBinding" bindingConfiguration="RealTimeOnlineSoapBinding" contract="RealTimeOnline.RealTimeOnline" name="RealTimeOnline" /> </client> </system.serviceModel> </configuration> If if I run this as is using code like this:var client = new RealTimeOnlineClient(); client.ClientCredentials.UserName.UserName = "TheUsername"; client.ClientCredentials.UserName.Password = "ThePassword"; … I get nothing in terms of WS-Security headers. The request is sent, but the the binding expects transport level security to be applied, rather than message level security. To fix this so that a WS-Security message header is sent the security mode can be changed to: <security mode="TransportWithMessageCredential" /> Now if I re-run I at least get a WS-Security header which looks like this:<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"> <s:Header> <o:Security s:mustUnderstand="1" xmlns:o="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <u:Timestamp u:Id="_0"> <u:Created>2012-11-24T02:55:18.011Z</u:Created> <u:Expires>2012-11-24T03:00:18.011Z</u:Expires> </u:Timestamp> <o:UsernameToken u:Id="uuid-18c215d4-1106-40a5-8dd1-c81fdddf19d3-1"> <o:Username>TheUserName</o:Username> <o:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText" >ThePassword</o:Password> </o:UsernameToken> </o:Security> </s:Header> Closer! Now the WS-Security header is there along with a timestamp field (which might not be accepted by some WS-Security expecting services), but there's no Nonce or created timestamp as required by my original service. Using a CustomBinding instead My next try was to go with a CustomBinding instead of basicHttpBinding as it allows a bit more control over the protocol and transport configurations for the binding. Specifically I can explicitly specify the message protocol(s) used. Using configuration file settings here's what the config file looks like:<?xml version="1.0"?> <configuration> <system.serviceModel> <bindings> <customBinding> <binding name="CustomSoapBinding"> <security includeTimestamp="false" authenticationMode="UserNameOverTransport" defaultAlgorithmSuite="Basic256" requireDerivedKeys="false" messageSecurityVersion="WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10"> </security> <textMessageEncoding messageVersion="Soap11"></textMessageEncoding> <httpsTransport maxReceivedMessageSize="2000000000"/> </binding> </customBinding> </bindings> <client> <endpoint address="https://notrealurl.com:443/services/RealTimeOnline" binding="customBinding" bindingConfiguration="CustomSoapBinding" contract="RealTimeOnline.RealTimeOnline" name="RealTimeOnline" /> </client> </system.serviceModel> <startup> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/> </startup> </configuration> This ends up creating a cleaner header that's missing the timestamp field which can cause some services problems. The WS-Security header output generated with the above looks like this:<s:Header> <o:Security s:mustUnderstand="1" xmlns:o="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <o:UsernameToken u:Id="uuid-291622ca-4c11-460f-9886-ac1c78813b24-1"> <o:Username>TheUsername</o:Username> <o:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText" >ThePassword</o:Password> </o:UsernameToken> </o:Security> </s:Header> This is closer as it includes only the username and password. The key here is the protocol for WS-Security:messageSecurityVersion="WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10" which explicitly specifies the protocol version. There are several variants of this specification but none of them seem to support the nonce unfortunately. This protocol does allow for optional omission of the Nonce and created timestamp provided (which effectively makes those keys optional). With some services I tried that requested a Nonce just using this protocol actually worked where the default basicHttpBinding failed to connect, so this is a possible solution for access to some services. Unfortunately for my target service that was not an option. The nonce has to be there. Creating Custom ClientCredentials As it turns out WCF doesn't have support for the Digest Nonce as part of WS-Security, and so as far as I can tell there's no way to do it just with configuration settings. I did a bunch of research on this trying to find workarounds for this, and I did find a couple of entries on StackOverflow as well as on the MSDN forums. However, none of these are particularily clear and I ended up using bits and pieces of several of them to arrive at a working solution in the end. http://stackoverflow.com/questions/896901/wcf-adding-nonce-to-usernametoken http://social.msdn.microsoft.com/Forums/en-US/wcf/thread/4df3354f-0627-42d9-b5fb-6e880b60f8ee The latter forum message is the more useful of the two (the last message on the thread in particular) and it has most of the information required to make this work. But it took some experimentation for me to get this right so I'll recount the process here maybe a bit more comprehensively. In order for this to work a number of classes have to be overridden: ClientCredentials ClientCredentialsSecurityTokenManager WSSecurityTokenizer The idea is that we need to create a custom ClientCredential class to hold the custom properties so they can be set from the UI or via configuration settings. The TokenManager and Tokenizer are mainly required to allow the custom credentials class to flow through the WCF pipeline and eventually provide custom serialization. Here are the three classes required and their full implementations:public class CustomCredentials : ClientCredentials { public CustomCredentials() { } protected CustomCredentials(CustomCredentials cc) : base(cc) { } public override System.IdentityModel.Selectors.SecurityTokenManager CreateSecurityTokenManager() { return new CustomSecurityTokenManager(this); } protected override ClientCredentials CloneCore() { return new CustomCredentials(this); } } public class CustomSecurityTokenManager : ClientCredentialsSecurityTokenManager { public CustomSecurityTokenManager(CustomCredentials cred) : base(cred) { } public override System.IdentityModel.Selectors.SecurityTokenSerializer CreateSecurityTokenSerializer(System.IdentityModel.Selectors.SecurityTokenVersion version) { return new CustomTokenSerializer(System.ServiceModel.Security.SecurityVersion.WSSecurity11); } } public class CustomTokenSerializer : WSSecurityTokenSerializer { public CustomTokenSerializer(SecurityVersion sv) : base(sv) { } protected override void WriteTokenCore(System.Xml.XmlWriter writer, System.IdentityModel.Tokens.SecurityToken token) { UserNameSecurityToken userToken = token as UserNameSecurityToken; string tokennamespace = "o"; DateTime created = DateTime.Now; string createdStr = created.ToString("yyyy-MM-ddThh:mm:ss.fffZ"); // unique Nonce value - encode with SHA-1 for 'randomness' // in theory the nonce could just be the GUID by itself string phrase = Guid.NewGuid().ToString(); var nonce = GetSHA1String(phrase); // in this case password is plain text // for digest mode password needs to be encoded as: // PasswordAsDigest = Base64(SHA-1(Nonce + Created + Password)) // and profile needs to change to //string password = GetSHA1String(nonce + createdStr + userToken.Password); string password = userToken.Password; writer.WriteRaw(string.Format( "<{0}:UsernameToken u:Id=\"" + token.Id + "\" xmlns:u=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd\">" + "<{0}:Username>" + userToken.UserName + "</{0}:Username>" + "<{0}:Password Type=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText\">" + password + "</{0}:Password>" + "<{0}:Nonce EncodingType=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary\">" + nonce + "</{0}:Nonce>" + "<u:Created>" + createdStr + "</u:Created></{0}:UsernameToken>", tokennamespace)); } protected string GetSHA1String(string phrase) { SHA1CryptoServiceProvider sha1Hasher = new SHA1CryptoServiceProvider(); byte[] hashedDataBytes = sha1Hasher.ComputeHash(Encoding.UTF8.GetBytes(phrase)); return Convert.ToBase64String(hashedDataBytes); } } Realistically only the CustomTokenSerializer has any significant code in. The code there deals with actually serializing the custom credentials using low level XML semantics by writing output into an XML writer. I can't take credit for this code - most of the code comes from the MSDN forum post mentioned earlier - I made a few adjustments to simplify the nonce generation and also added some notes to allow for PasswordDigest generation. Per spec the nonce is nothing more than a unique value that's supposed to be 'random'. I'm thinking that this value can be any string that's unique and a GUID on its own probably would have sufficed. Comments on other posts that GUIDs can be potentially guessed are highly exaggerated to say the least IMHO. To satisfy even that aspect though I added the SHA1 encryption and binary decoding to give a more random value that would be impossible to 'guess'. The original example from the forum post used another level of encoding and decoding to string in between - but that really didn't accomplish anything but extra overhead. The header output generated from this looks like this:<s:Header> <o:Security s:mustUnderstand="1" xmlns:o="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <o:UsernameToken u:Id="uuid-f43d8b0d-0ebb-482e-998d-f544401a3c91-1" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"> <o:Username>TheUsername</o:Username> <o:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">ThePassword</o:Password> <o:Nonce EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary" >PjVE24TC6HtdAnsf3U9c5WMsECY=</o:Nonce> <u:Created>2012-11-23T07:10:04.670Z</u:Created> </o:UsernameToken> </o:Security> </s:Header> which is exactly as it should be. Password Digest? In my case the password is passed in plain text over an SSL connection, so there's no digest required so I was done with the code above. Since I don't have a service handy that requires a password digest,  I had no way of testing the code for the digest implementation, but here is how this is likely to work. If you need to pass a digest encoded password things are a little bit trickier. The password type namespace needs to change to: http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#Digest and then the password value needs to be encoded. The format for password digest encoding is this: Base64(SHA-1(Nonce + Created + Password)) and it can be handled in the code above with this code (that's commented in the snippet above): string password = GetSHA1String(nonce + createdStr + userToken.Password); The entire WriteTokenCore method for digest code looks like this:protected override void WriteTokenCore(System.Xml.XmlWriter writer, System.IdentityModel.Tokens.SecurityToken token) { UserNameSecurityToken userToken = token as UserNameSecurityToken; string tokennamespace = "o"; DateTime created = DateTime.Now; string createdStr = created.ToString("yyyy-MM-ddThh:mm:ss.fffZ"); // unique Nonce value - encode with SHA-1 for 'randomness' // in theory the nonce could just be the GUID by itself string phrase = Guid.NewGuid().ToString(); var nonce = GetSHA1String(phrase); string password = GetSHA1String(nonce + createdStr + userToken.Password); writer.WriteRaw(string.Format( "<{0}:UsernameToken u:Id=\"" + token.Id + "\" xmlns:u=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd\">" + "<{0}:Username>" + userToken.UserName + "</{0}:Username>" + "<{0}:Password Type=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#Digest\">" + password + "</{0}:Password>" + "<{0}:Nonce EncodingType=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary\">" + nonce + "</{0}:Nonce>" + "<u:Created>" + createdStr + "</u:Created></{0}:UsernameToken>", tokennamespace)); } I had no service to connect to to try out Digest auth - if you end up needing it and get it to work please drop a comment… How to use the custom Credentials The easiest way to use the custom credentials is to create the client in code. Here's a factory method I use to create an instance of my service client:  public static RealTimeOnlineClient CreateRealTimeOnlineProxy(string url, string username, string password) { if (string.IsNullOrEmpty(url)) url = "https://notrealurl.com:443/cows/services/RealTimeOnline"; CustomBinding binding = new CustomBinding(); var security = TransportSecurityBindingElement.CreateUserNameOverTransportBindingElement(); security.IncludeTimestamp = false; security.DefaultAlgorithmSuite = SecurityAlgorithmSuite.Basic256; security.MessageSecurityVersion = MessageSecurityVersion.WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10; var encoding = new TextMessageEncodingBindingElement(); encoding.MessageVersion = MessageVersion.Soap11; var transport = new HttpsTransportBindingElement(); transport.MaxReceivedMessageSize = 20000000; // 20 megs binding.Elements.Add(security); binding.Elements.Add(encoding); binding.Elements.Add(transport); RealTimeOnlineClient client = new RealTimeOnlineClient(binding, new EndpointAddress(url)); // to use full client credential with Nonce uncomment this code: // it looks like this might not be required - the service seems to work without it client.ChannelFactory.Endpoint.Behaviors.Remove<System.ServiceModel.Description.ClientCredentials>(); client.ChannelFactory.Endpoint.Behaviors.Add(new CustomCredentials()); client.ClientCredentials.UserName.UserName = username; client.ClientCredentials.UserName.Password = password; return client; } This returns a service client that's ready to call other service methods. The key item in this code is the ChannelFactory endpoint behavior modification that that first removes the original ClientCredentials and then adds the new one. The ClientCredentials property on the client is read only and this is the way it has to be added.   Summary It's a bummer that WCF doesn't suport WSE Security authentication with nonce values out of the box. From reading the comments in posts/articles while I was trying to find a solution, I found that this feature was omitted by design as this protocol is considered unsecure. While I agree that plain text passwords are rarely a good idea even if they go over secured SSL connection as WSE Security does, there are unfortunately quite a few services (mosly Java services I suspect) that use this protocol. I've run into this twice now and trying to find a solution online I can see that this is not an isolated problem - many others seem to have struggled with this. It seems there are about a dozen questions about this on StackOverflow all with varying incomplete answers. Hopefully this post provides a little more coherent content in one place. Again I marvel at WCF and its breadth of support for protocol features it has in a single tool. And even when it can't handle something there are ways to get it working via extensibility. But at the same time I marvel at how freaking difficult it is to arrive at these solutions. I mean there's no way I could have ever figured this out on my own. It takes somebody working on the WCF team or at least being very, very intricately involved in the innards of WCF to figure out the interconnection of the various objects to do this from scratch. Luckily this is an older problem that has been discussed extensively online and I was able to cobble together a solution from the online content. I'm glad it worked out that way, but it feels dirty and incomplete in that there's a whole learning path that was omitted to get here… Man am I glad I'm not dealing with SOAP services much anymore. REST service security - even when using some sort of federation is a piece of cake by comparison :-) I'm sure once standards bodies gets involved we'll be right back in security standard hell…© Rick Strahl, West Wind Technologies, 2005-2012Posted in WCF  Web Services   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

  • Do you develop with security in mind?

    - by MattyD
    I was listening to a podcast on Security Now and they mentioned about how a lot of the of the security problems found in Flash were because when flash was first developed it wasdn't built with security in mind because it didn't need to thus flash has major security flaws in its design etc. I know best practices state that you should build secure first etc. Some people or companies don't always follow 'best practice'... My question is do you develop to be secure or do you build with all the desired functionality etc then alter the code to be secure (Whatever the project maybe) (I realise that this question could be a possible duplicate of Do you actively think about security when coding? but it is different in the fact of actually process of building the software/application and design of said software/application)

  • Is osTicket secure/private enough

    - by Andy
    I was going to use osTicket as my 'help desk' for my website, however I just got a little bit concerned when I realised that the clients' login details to see their support tickets are only their email address and a ticket ID. I am probably going over the top with security though, which is why I wanted to get some second opinions on how secure osTicket actually is and whether I should use it with my website. I run a software company, so chances are licence keys may be included in support tickets which are obviously sensitive information and valuable - so I want to ensure that the likelihood of a support ticket being hacked is very low. If there is any plugins/additions to make osTicket more 'secure', I would appreciate it if you could point me to them. Otherwise if there are any more free, more suited, help desk softwares out there please let me know. Thanks in advance

  • Moving the Oracle User Experience Forward with the New Release 7 Simplified UI for Oracle Sales Cloud

    - by mvaughan
    By Kathy Miedema, Oracle Applications User ExperienceIn September 2013, Release 7 for Oracle Cloud Applications became generally available for Oracle Sales Cloud and HCM Cloud. This significant release allowed the Oracle Applications User Experience (UX) team to finally talk freely about Simplified UI, a user experience project in the works since Oracle OpenWorld 2012. Simplified UI represents the direction that the Oracle user experience – for all of its enterprise applications – is heading. Oracle’s Apps UX team began by building a Simplified UI for sales representatives. You can find that today in Release 7, and it was demoed extensively during OpenWorld 2013 in San Francisco. This screenshot shows how Opportunities appear in the new Simplified UI for Oracle Sales Cloud, a user interface built for sales reps.Analyst Rebecca Wettemann, vice president of Nucleus Research, saw Simplified UI at Oracle Openworld 2013 and talked about it with CRM Buyer in “Oracle Revs Its Cloud Engines for a Better Customer Experience.” Wettemann said there are distinct themes to the latest release: "One is usability. Oracle Sales Cloud, for example, is designed to have zero training for onboarding sales reps, which it does," she explained. "It is quite impressive, actually -- the intuitive nature of the application and the design work they have done with this goal in mind."The software uses as few buttons and fields as possible, she pointed out. "The sales rep doesn't have to ask, 'what is the next step?' because she can see what it is."In fact, there are three themes driving the usability that Wettemann noted. They are simplicity, mobility, and extensibility, and we write more about them on the Usable Apps web site. These three themes embody the strategy for Oracle’s cloud applications user experiences.  Simplified UI for Oracle Sales CloudIn developing a Simplified UI for Oracle Sales Cloud, Oracle’s UX team concentrated on the tasks that sales reps need to do most frequently, and are most important. “Knowing that the majority of their work lives are spent on the road and on the go, they need to be able to quickly get in and qualify and convert their leads, monitor and progress their opportunities, update their customer and contact information, and manage their schedule,” Jeremy Ashley, Vice President of the Applications UX team, said.Ashley said the Apps UX team has a good reason for creating a Simplified UI that focuses on self-service. “Sales people spend the day selling stuff,” he said. “The only reason they use software is because the company wants to track what they’re doing.” Traditional systems of tracking that information include filling in a spreadsheet of leads or sales. Oracle wants to automate this process for the salesperson, and enable that person to keep everyone who needs to know up-to-date easily and quickly. Simplified UI addresses that problem by providing light-touch input.  “It has to be useful to the salesperson,” Ashley said about the Sales Cloud user experience. Simplified UI can tell sales reps about key opportunities, or provide information about a contact in just a click or two. Customer information is accessible quickly and easily with Simplified UI for the Oracle Sales Cloud.Simplified UI for Sales Cloud can also be extended easily, Ashley said. Users usually just need to add various business fields or create and modify analytical reports. The way that Simplified UI is constructed allows extensibility to happen by hiding or showing a few necessary fields. The Settings user interface, starting in release 7, allows for the simple configuration of the most important visual elements. “With Sales cloud, we identified a need to make the application useful and very simple,” Ashley said. Simplified UI meets that need. Where can you find out more?To find out more about the simplified UI and Oracle’s ongoing investment in applications user experience innovations, come to one of our sessions at a user group conference near you. Stay tuned to the Voice of User Experience (VoX) blog – the next post will be about Simplified UI and HCM Cloud.

  • Is Cloud Security Holding Back Social SaaS?

    - by Mike Stiles
    The true promise of social data co-mingling with enterprise data to influence and inform social marketing (all marketing really) lives in cloud computing. The cloud brings processing power, services, speed and cost savings the likes of which few organizations could ever put into action on their own. So why wouldn’t anyone jump into SaaS (Software as a Service) with both feet? Cloud security. Being concerned about security is proper and healthy. That just means you’re a responsible operator. Whether it’s protecting your customers’ data or trying to stay off the radar of regulatory agencies, you have plenty of reasons to make sure you’re as protected from hacking, theft and loss as you can possibly be. But you also have plenty of reasons to not let security concerns freeze you in your tracks, preventing you from innovating, moving the socially-enabled enterprise forward, and keeping up with competitors who may not be as skittish regarding SaaS technology adoption. Over half of organizations are transferring sensitive or confidential data to the cloud, an increase of 10% over last year. With the roles and responsibilities of CMO’s, CIO’s and other C’s changing, the first thing you should probably determine is who should take point on analyzing cloud software options, providers, and policies. An oft-quoted Ponemon Institute study found 36% of businesses don’t have a cloud security policy at all. So that’s as good a place to start as any. What applications and data are you comfortable housing in the cloud? Do you have a classification system for data that clearly spells out where data types can go and how they can be used? Who, both internally and at the cloud provider, will function as admins? What are the different levels of admin clearance? Will your security policies and procedures sync up with those of your cloud provider? The key is verifiable trust. Trust in cloud security is actually going up. 1/3 of organizations polled say it’s the cloud provider who should be responsible for data protection. And when you look specifically at SaaS providers, that expectation goes up to 60%. 57% “strongly agree” or “agree” there’s more confidence in cloud providers’ ability to protect data. In fact, some businesses bypass the “verifiable” part of verifiable trust. Just over half have no idea what their cloud provider does to protect data. And yet, according to the “Private Cloud Vision vs. Reality” InformationWeek Report, 82% of organizations say security/data privacy are one of the main reasons they’re still holding the public cloud at arm’s length. That’s going to be a tough position to maintain, because just as social is rapidly changing the face of marketing, big data is rapidly changing the face of enterprise IT. Netflix, who’s particularly big on the benefits of the cloud, says, "We're systematically disassembling the corporate IT components." An enterprise can never realize the full power of big data, nor get the full potential value out of it, if it’s unwilling to enable the integrations and dataset connections necessary in the cloud. Because integration is called for to reduce fragmentation, a standardized platform makes a lot of sense. With multiple components crafted to work together, you’re maximizing scalability, optimization, cost effectiveness, and yes security and identity management benefits. You can see how the incentive is there for cloud companies to develop and add ever-improving security features, making cloud computing an eventual far safer bet than traditional IT. @mikestilesPhoto: stock.xchng

  • Books or guides regarding secure key storage and database encryption

    - by Matty
    I have an idea for a SaaS product I want to create, however, this product will store extremely sensitive data that needs to be encrypted at rest. The trouble is not so much the encryption, but the problem of securely storing the keys so that in the event the server was somehow compromised, the keys couldn't just be recovered and used to decrypt the database. Are there any decent books to guides regarding database encryption, and in particular secure key storage? This seems to be a less than straightforward topic and something that is difficult to get right. I'm seeing multiple ways to attack such a system, but unable to come up with one that is secure enough to store highly confidential information.
