  • Derek Brink shares "Worst Practices in IT Security"

    - by Darin Pendergraft
    Derek Brink is Vice President and Research Fellow in IT Security for the Aberdeen Group.  He has established himself as an IT Security Expert having a long and impressive career with companies and organizations ranging from RSA, Sun, HP, the PKI Forum and the Central Intelligence Agency.  So shouldn't he be talking about "Best Practices in IT Security?" In his latest blog he talks about the thought processes that drive the wrong behavior, and very cleverly shows how that incorrect thinking exposes weaknesses in our IT environments. Check out his latest blog post titled: "The Screwtape CISO: Memo #1 (silos, stovepipes and point solutions)"

  • ADF Desktop Integration Security Explained

    - by juan.ruiz
    ADFdi provides a secure access to spreadsheets within MS-Excel. Developers as well as administrators could wonder how the security features work in this mixed layout -having MS-Excel accessing JavaEE business services? and also what do system administrators should expect when deploying an ADF solution that offers ADFdi capabilities? Shaun Logan from the ADFdi team published an excellent article back in January where you can find in a great detail the ADF desktop integration security features and implementation. You can find the article here: http://www.oracle.com/technology/products/jdev/11/collateral/security%20whitepaper%20for%20adfdi%20r1%20final.pdf Enjoy!

  • ASP.NET WebAPI Security 2: Identity Architecture

    - by Your DisplayName here!
    Pedro has beaten me to the punch with a detailed post (and diagram) about the WebAPI hosting architecture. So go read his post first, then come back so we can have a closer look at what that means for security. The first important takeaway is that WebAPI is hosting independent-  currently it ships with two host integration implementations – one for ASP.NET (aka web host) and WCF (aka self host). Pedro nicely shows the integration into the web host. Self hosting is not done yet so we will mainly focus on the web hosting case and I will point out security related differences when they exist. The interesting part for security (amongst other things of course) is the HttpControllerHandler (see Pedro’s diagram) – this is where the host specific representation of an HTTP request gets converted to the WebAPI abstraction (called HttpRequestMessage). The ConvertRequest method does the following: Create a new HttpRequestMessage. Copy URI, method and headers from the HttpContext. Copies HttpContext.User to the Properties<string, object> dictionary on the HttpRequestMessage. The key used for that can be found on HttpPropertyKeys.UserPrincipalKey (which resolves to “MS_UserPrincipal”). So the consequence is that WebAPI receives whatever IPrincipal has been set by the ASP.NET pipeline (in the web hosting case). Common questions are: Are there situations where is property does not get set? Not in ASP.NET – the DefaultAuthenticationModule in the HTTP pipeline makes sure HttpContext.User (and Thread.CurrentPrincipal – more on that later) are always set. Either to some authenticated user – or to an anonymous principal. This may be different in other hosting environments (again more on that later). Why so generic? Keep in mind that WebAPI is hosting independent and may run on a host that materializes identity completely different compared to ASP.NET (or .NET in general). This gives them a way to evolve the system in the future. How does WebAPI code retrieve the current client identity? HttpRequestMessage has an extension method called GetUserPrincipal() which returns the property as an IPrincipal. A quick look at self hosting shows that the moral equivalent of HttpControllerHandler.ConvertRequest() is HttpSelfHostServer.ProcessRequestContext(). Here the principal property gets only set when the host is configured for Windows authentication (inconsisteny). Do I like that? Well – yes and no. Here are my thoughts: I like that it is very straightforward to let WebAPI inherit the client identity context of the host. This might not always be what you want – think of an ASP.NET app that consists of UI and APIs – the UI might use Forms authentication, the APIs token based authentication. So it would be good if the two parts would live in a separate security world. It makes total sense to have this generic hand off point for identity between the host and WebAPI. It also makes total sense for WebAPI plumbing code (especially handlers) to use the WebAPI specific identity abstraction. But – c’mon we are running on .NET. And the way .NET represents identity is via IPrincipal/IIdentity. That’s what every .NET developer on this planet is used to. So I would like to see a User property of type IPrincipal on ApiController. I don’t like the fact that Thread.CurrentPrincipal is not populated. T.CP is a well established pattern as a one stop shop to retrieve client identity on .NET.  That makes a lot of sense – even if the name is misleading at best. There might be existing library code you want to call from WebAPI that makes use of T.CP (e.g. PrincipalPermission, or a simple .Name or .IsInRole()). Having the client identity as an ambient property is useful for code that does not have access to the current HTTP request (for calling GetUserPrincipal()). I don’t like the fact that that the client identity conversion from host to WebAPI is inconsistent. This makes writing security plumbing code harder. I think the logic should always be: If the host has a client identity representation, copy it. If not, set an anonymous principal on the request message. Btw – please don’t annoy me with the “but T.CP is static, and static is bad for testing” chant. T.CP is a getter/setter and, in fact I find it beneficial to be able to set different security contexts in unit tests before calling in some logic. And, in case you have wondered – T.CP is indeed thread static (and the name comes from a time where a logical operation was bound to a thread – which is not true anymore). But all thread creation APIs in .NET actually copy T.CP to the new thread they create. This is the case since .NET 2.0 and is certainly an improvement compared to how Win32 does things. So to sum it up: The host plumbing copies the host client identity to WebAPI (this is not perfect yet, but will surely be improved). or in other words: The current WebAPI bits don’t ship with any authentication plumbing, but solely use whatever authentication (and thus client identity) is set up by the host. WebAPI developers can retrieve the client identity from the HttpRequestMessage. Hopefully my proposed changes around T.CP and the User property on ApiController will be added. In the next post, I will detail how to add WebAPI specific authentication support, e.g. for Basic Authentication and tokens. This includes integrating the notion of claims based identity. After that we will look at the built-in authorization bits and how to improve them as well. Stay tuned.

  • System Account Logon Failures ever 30 seconds

    - by floyd
    We have two Windows 2008 R2 SP1 servers running in a SQL failover cluster. On one of them we are getting the following events in the security log every 30 seconds.

  • Simple, current how-to install mod-security on cPanel server?

    - by linux911
    Does anyone have or know of a simple, up to date how to for installing mod-security on cPanel and configuring it after install? Every how to on the web I've found is at least two years old and is based on a mod-security addon function in cPanel which doesn't exist anymore. There are a couple of free add ons to simplify selecting rule files (configserver's for example) but there's no documentation on which rules a cPanel system "should" be using and so on.

  • Corliss Expert Group Home Security: How to Secure Your Home without Spending Too Much?

    - by Mika Esmond
    HOME SECURITY: HOW TO SECURE YOUR HOME WITHOUT SPENDING TOO MUCH Imagine if there were no burglar or criminals who threaten the safety of our homes; we will be surprised how much savings we would have on several things we do to secure ourselves and our loved ones. We would not need fences, gates with locks, doors locks, window grills, CCTV cams, perimeter lighting, shotguns and baseball bats. The cost of maintaining these things can run up to the entire cost of building another room or, in some cases, a whole new house. The rationale for home security is the same for national security. A nation maintains an army whether it has enemies or not; so, whether burglars will come or not, we have to prepare for the eventuality. Hence, we end up spending for something we might never put into the actual use it was intended for. You buy a pistol and when a burglar breaks in you fire the gun either to scare or disable the intruder. We hope we will never have to use these things; but we still buy them for the peace of mind that comes from knowing we can secure or protect our family and home.

  • Security Trimmed Cross Site Collection Navigation

    - by Sahil Malik
    Ad:: SharePoint 2007 Training in .NET 3.5 technologies (more information). This article will serve as documentation of a fully functional codeplex project that I just created. This project will give you a WebPart that will give you security trimmed navigation across site collections. The first question is, why create such a project? In every single SharePoint project you will do, one question you will always be faced with is, what should the boundaries of sites be, and what should the boundaries of site collections be? There is no good or bad answer to this, because it really really depends on your needs. There are some factors in play here. Site Collections will allow you to scale, as a Site collection is the smallest entity you can put inside a content database Site collections will allow you to offer different levels of SLAs, because you put a site collection on a separate content database, and put that database on a separate server. Site collections are a security boundary – and they can be moved around at will without affecting other site collections. Site collections are also a branding boundary. They are also a feature deployment boundary, so you can have two site collections on the same web application with completely different nature of services. But site collections break navigation, i.e. a site collection at “/”, and a site collection at “/sites/mySiteCollection”, are completely independent of each other. If you have access to both, the navigation of / won’t show you a link to /sites/mySiteCollection. Some people refer to this as a huge issue in SharePoint. Luckily, some workarounds exist. A long time ago, I had blogged about “Implementing Consistent Navigation across Site Collections”. That approach was a no-code solution, it worked – it gave you a consistent navigation across site collections. But, it didn’t work in a security trimmed fashion! i.e., if I don’t have access to Site Collection ‘X’, it would still show me a link to ‘X’. Well this project gets around that issue. Simply deploy this project, and it’ll give you a WebPart. You can use that WebPart as either a webpart or as a server control dropped via SharePoint designer, and it will give you Security Trimmed Cross Site Collection Navigation. The code has been written for SP2010, but it will work in SP2007 with the help of http://spwcfsupport.codeplex.com . What do I need to do to make it work? I’m glad you asked! Simple! Deploy the .wsp (which you can download here). This will give you a site collection feature called “Winsmarts Cross Site Collection Navigation” as shown below. Go ahead and activate it, and this will give you a WebPart called “Winsmarts Navigation Web Part” as shown below: Just drop this WebPart on your page, and it will show you all site collections that the currently logged in user has access to. Really it’s that easy! This is shown as below - In the above example, I have two site collections that I created at /sites/SiteCollection1 and /sites/SiteCollection2. The navigation shows the titles. You see some extraneous crap as well, you might want to clean that – I’ll talk about that in a minute. What? You’re running into problems? If the problem you’re running into is that you are prompted to login three times, and then it shows a blank webpart that says “Loading your applications ..” and then craps out!, then most probably you’re using a different authentication scheme. Behind the scenes I use a custom WCF service to perform this job. OOTB, I’ve set it to work with NTLM, but if you need to make it work alternate authentications such as forms based auth, or client side certs, you will need to edit the %14%\ISAPI\Winsmarts.CrossSCNav\web.config file, specifically, this section - 1: <bindings> 2: <webHttpBinding> 3: <binding name="customWebHttpBinding"> 4: <security mode="TransportCredentialOnly"> 5: <transport clientCredentialType="Ntlm"/> 6: </security> 7: </binding> 8: </webHttpBinding> 9: </bindings> For Kerberos, change the “clientCredentialType” to “Windows” For Forms auth, remove that transport line For client certs – well that’s a bit more involved, but it’s just web.config changes – hit a good book on WCF or hire me for a billion trillion $. But fair warning, I might be too busy to help immediately. If you’re running into a different problem, please leave a comment below, but the code is pretty rock solid, so .. hmm .. check what you’re doing! BTW, I don’t  make any guarantee/warranty on this – if this code makes you sterile, unpopular, bad hairstyle, anything else, that is your problem! But, there are some known issues - I wrote this as a concept – you can easily extend it to be more flexible. Example, hierarchical nav, or, horizontal nav, jazzy effects with jquery or silverlight– all those are possible very very easily. This webpart is not smart enough to co-exist with another instance of itself on the same page. I can easily extend it to do so, which I will do in my spare(!?) time! Okay good! But that’s not all! As you can see, just dropping the WebPart may show you many extraneous site collections, or maybe you want to restrict which site collections are shown, or exclude a certain site collection to be shown from the navigation. To support that, I created a property on the WebPart called “UrlMatchPattern”, which is a regex expression you specify to trim the results :). So, just edit the WebPart, and specify a string property of “http://sp2010/sites/” as shown below. Note that you can put in whatever regex expression you want! So go crazy, I don’t care! And this gives you a cleaner look.   w00t! Enjoy! Comment on the article ....

  • [GEEK SCHOOL] Network Security 4: Windows Firewall: Your System’s Best Defense

    - by Ciprian Rusen
    If you have your computer connected to a network, or directly to your Internet connection, then having a firewall is an absolute necessity. In this lesson we will discuss the Windows Firewall – one of the best security features available in Windows! The Windows Firewall made its debut in Windows XP. Prior to that, Windows system needed to rely on third-party solutions or dedicated hardware to protect them from network-based attacks. Over the years, Microsoft has done a great job with it and it is one of the best firewalls you will ever find for Windows operating systems. Seriously, it is so good that some commercial vendors have decided to piggyback on it! Let’s talk about what you will learn in this lesson. First, you will learn about what the Windows Firewall is, what it does, and how it works. Afterward, you will start to get your hands dirty and edit the list of apps, programs, and features that are allowed to communicate through the Windows Firewall depending on the type of network you are connected to. Moving on from there, you will learn how to add new apps or programs to the list of allowed items and how to remove the apps and programs that you want to block. Last but not least, you will learn how to enable or disable the Windows Firewall, for only one type of networks or for all network connections. By the end of this lesson, you should know enough about the Windows Firewall to use and manage it effectively. What is the Windows Firewall? Windows Firewall is an important security application that’s built into Windows. One of its roles is to block unauthorized access to your computer. The second role is to permit authorized data communications to and from your computer. Windows Firewall does these things with the help of rules and exceptions that are applied both to inbound and outbound traffic. They are applied depending on the type of network you are connected to and the location you have set for it in Windows, when connecting to the network. Based on your choice, the Windows Firewall automatically adjusts the rules and exceptions applied to that network. This makes the Windows Firewall a product that’s silent and easy to use. It bothers you only when it doesn’t have any rules and exceptions for what you are trying to do or what the programs running on your computer are trying to do. If you need a refresher on the concept of network locations, we recommend you to read our How-To Geek School class on Windows Networking. Another benefit of the Windows Firewall is that it is so tightly and nicely integrated into Windows and all its networking features, that some commercial vendors decided to piggyback onto it and use it in their security products. For example, products from companies like Trend Micro or F-Secure no longer provide their proprietary firewall modules but use the Windows Firewall instead. Except for a few wording differences, the Windows Firewall works the same in Windows 7 and Windows 8.x. The only notable difference is that in Windows 8.x you will see the word “app” being used instead of “program”. Where to Find the Windows Firewall By default, the Windows Firewall is turned on and you don’t need to do anything special in order for it work. You will see it displaying some prompts once in a while but they show up so rarely that you might forget that is even working. If you want to access it and configure the way it works, go to the Control Panel, then go to “System and Security” and select “Windows Firewall”. Now you will see the Windows Firewall window where you can get a quick glimpse on whether it is turned on and the type of network you are connected to: private networks or public network. For the network type that you are connected to, you will see additional information like: The state of the Windows Firewall How the Windows Firewall deals with incoming connections The active network When the Windows Firewall will notify you You can easily expand the other section and view the default settings that apply when connecting to networks of that type. If you have installed a third-party security application that also includes a firewall module, chances are that the Windows Firewall has been disabled, in order to avoid performance issues and conflicts between the two security products. If that is the case for your computer or device, you won’t be able to view any information in the Windows Firewall window and you won’t be able to configure the way it works. Instead, you will see a warning that says: “These settings are being managed by vendor application – Application Name”. In the screenshot below you can see an example of how this looks. How to Allow Desktop Applications Through the Windows Firewall Windows Firewall has a very comprehensive set of rules and most Windows programs that you install add their own exceptions to the Windows Firewall so that they receive network and Internet access. This means that you will see prompts from the Windows Firewall on occasion, generally when you install programs that do not add their own exceptions to the Windows Firewall’s list. In a Windows Firewall prompt, you are asked to select the network locations to which you allow access for that program: private networks or public networks. By default, Windows Firewall selects the checkbox that’s appropriate for the network you are currently using. You can decide to allow access for both types of network locations or just to one of them. To apply your setting press “Allow access”. If you want to block network access for that program, press “Cancel” and the program will be set as blocked for both network locations. At this step you should note that only administrators can set exceptions in the Windows Firewall. If you are using a standard account without administrator permissions, the programs that do not comply with the Windows Firewall rules and exceptions are automatically blocked, without any prompts being shown. You should note that in Windows 8.x you will never see any Windows Firewall prompts related to apps from the Windows Store. They are automatically given access to the network and the Internet based on the assumption that you are aware of the permissions they require based on the information displayed by the Windows Store. Windows Firewall rules and exceptions are automatically created for each app that you install from the Windows Store. However, you can easily block access to the network and the Internet for any app, using the instructions in the next section. How to Customize the Rules for Allowed Apps Windows Firewall allows any user with an administrator account to change the list of rules and exceptions applied for apps and desktop programs. In order to do this, first start the Windows Firewall. On the column on the left, click or tap “Allow an app or feature through Windows Firewall” (in Windows 8.x) or “Allow a program or feature through Windows Firewall” (in Windows 7). Now you see the list of apps and programs that are allowed to communicate through the Windows Firewall. At this point, the list is grayed out and you can only view which apps, features, and programs have rules that are enabled in the Windows Firewall.

    - by pinaldave
    This blog post is inspired from Beginning SQL Joes 2 Pros: The SQL Hands-On Guide for Beginners – SQL Exam Prep Series 70-433 – Volume 1. [Amazon] | [Flipkart] | [Kindle] | [IndiaPlaza] This is follow up blog post of my earlier blog post on the same subject - SQL SERVER – Introduction to SQL Server Security – A Primer. In the article we discussed various basics terminology of the security. The article further covers following important concepts of security. Granting Permissions Denying Permissions Revoking Permissions Above three are the most important concepts related to security and SQL Server.  There are many more things one has to learn but without beginners fundamentals one can’t learn the advanced  concepts. Let us have small quiz and check how many of you get the fundamentals right. Quiz 1) If you granted Phil control to the server, but denied his ability to create databases, what would his effective permissions be? Phil can do everything. Phil can do nothing. Phil can do everything except create databases. 2) If you granted Phil control to the server and revoked his ability to create databases, what would his effective permissions be? Phil can do everything. Phil can do nothing. Phil can do everything except create databases. 3) You have a login named James who has Control Server permission. You want to elimintate his ability to create databases without affecting any other permissions. What SQL statement would you use? ALTER LOGIN James DISABLE DROP LOGIN James DENY CREATE DATABASE To James REVOKE CREATE DATABASE To James GRANT CREATE DATABASE To James Now make sure that you write down all the answers on the piece of paper. Watch following video and read earlier article over here. If you want to change the answer you still have chance.

  • Grow Your Business with Security

    - by Darin Pendergraft
    Author: Kevin Moulton Kevin Moulton has been in the security space for more than 25 years, and with Oracle for 7 years. He manages the East EnterpriseSecurity Sales Consulting Team. He is also a Distinguished Toastmaster. Follow Kevin on Twitter at twitter.com/kevin_moulton, where he sometimes tweets about security, but might also tweet about running, beer, food, baseball, football, good books, or whatever else grabs his attention. Kevin will be a regular contributor to this blog so stay tuned for more posts from him. It happened again! There I was, reading something interesting online, and realizing that a friend might find it interesting too. I clicked on the little email link, thinking that I could easily forward this to my friend, but no! Instead, a new screen popped up where I was asked to create an account. I was expected to create a User ID and password, not to mention providing some personally identifiable information, just for the privilege of helping that website spread their word. Of course, I didn’t want to have to remember a new account and password, I didn’t want to provide the requisite information, and I didn’t want to waste my time. I gave up, closed the web page, and moved on to something else. I was left with a bad taste in my mouth, and my friend might never find her way to this interesting website. If you were this content provider, would this be the outcome you were looking for? A few days later, I had a similar experience, but this one went a little differently. I was surfing the web, when I happened upon some little chotcke that I just had to have. I added it to my cart. When I went to buy the item, I was again brought to a page to create account. Groan! But wait! On this page, I also had the option to sign in with my OpenID account, my Facebook account, my Yahoo account, or my Google Account. I have all of those! No new account to create, no new password to remember, and no personally identifiable information to be given to someone else (I’ve already given it all to those other guys, after all). In this case, the vendor was easy to deal with, and I happily completed the transaction. That pleasant experience will bring me back again. This is where security can grow your business. It’s a differentiator. You’ve got to have a presence on the web, and that presence has to take into account all the smart phones everyone’s carrying, and the tablets that took over cyber Monday this year. If you are a company that a customer can deal with securely, and do so easily, then you are a company customers will come back to again and again. I recently had a need to open a new bank account. Every bank has a web presence now, but they are certainly not all the same. I wanted one that I could deal with easily using my laptop, but I also wanted 2-factor authentication in case I had to login from a shared machine, and I wanted an app for my iPad. I found a bank with all three, and that’s who I am doing business with. Let’s say, for example, that I’m in a regular Texas Hold-em game on Friday nights, so I move a couple of hundred bucks from checking to savings on Friday afternoons. I move a similar amount each week and I do it from the same machine. The bank trusts me, and they trust my machine. Most importantly, they trust my behavior. This is adaptive authentication. There should be no reason for my bank to make this transaction difficult for me. Now let's say that I login from a Starbucks in Uzbekistan, and I transfer $2,500. What should my bank do now? Should they stop the transaction? Should they call my home number? (My former bank did exactly this once when I was taking money out of an ATM on a business trip, when I had provided my cell phone number as my primary contact. When I asked them why they called my home number rather than my cell, they told me that their “policy” is to call the home number. If I'm on the road, what exactly is the use of trying to reach me at home to verify my transaction?) But, back to Uzbekistan… Should my bank assume that I am happily at home in New Jersey, and someone is trying to hack into my account? Perhaps they think they are protecting me, but I wouldn’t be very happy if I happened to be traveling on business in Central Asia. What if my bank were to automatically analyze my behavior and calculate a risk score? Clearly, this scenario would be outside of my typical behavior, so my risk score would necessitate something more than a simple login and password. Perhaps, in this case, a one-time password to my cell phone would prove that this is not just some hacker half way around the world. But, what if you're not a bank? Do you need this level of security? If you want to be a business that is easy to deal with while also protecting your customers, then of course you do. You want your customers to trust you, but you also want them to enjoy doing business with you. Make it easy for them to do business with you, and they’ll come back, and perhaps even Tweet about it, or Like you, and then their friends will follow. How can Oracle help? Oracle has the technology and expertise to help you to grown your business with security. Oracle Adaptive Access Manager will help you to prevent fraud while making it easier for your customers to do business with you by providing the risk analysis I discussed above, step-up authentication, and much more. Oracle Mobile and Social Access Service will help you to secure mobile access to applications by expanding on your existing back-end identity management infrastructure, and allowing your customers to transact business with you using the social media accounts they already know. You also have device fingerprinting and metrics to help you to grow your business securely. Security is not just a cost anymore. It’s a way to set your business apart. With Oracle’s help, you can be the business that everyone’s tweeting about. Image courtesy of Flickr user shareski
