• What are some topics you'd like to see covered in an 'Introduction to Network Security' book?

  - by seth.vargo

  I'm trying to put together a list of topics in Network Security and prioritize them accordingly. A little background on the book - we are trying to gear the text towards college students, as an introduction to security, and toward IT professionals who have recently been tasked with securing a network. The idea is to create a book that covers the most vital and important parts of securing a network with no assumptions. So, if you were a novice student interested in network security OR an IT professional who needed a crash course on network security, what topics do you feel would be of the upmost importance in such a text?

• Security in Software

  The term security has many meanings based on the context and perspective in which it is used. Security from the perspective of software/system development is the continuous process of maintaining confidentiality, integrity, and availability of a system, sub-system, and system data. This definition at a very high level can be restated as the following: Computer security is a continuous process dealing with confidentiality, integrity, and availability on multiple layers of a system. Key Aspects of Software Security Integrity Confidentiality Availability Integrity within a system is the concept of ensuring only authorized users can only manipulate information through authorized methods and procedures. An example of this can be seen in a simple lead management application.  If the business decided to allow each sales member to only update their own leads in the system and sales managers can update all leads in the system then an integrity violation would occur if a sales member attempted to update someone else’s leads. An integrity violation occurs when a team member attempts to update someone else’s lead because it was not entered by the sales member.  This violates the business rule that leads can only be update by the originating sales member. Confidentiality within a system is the concept of preventing unauthorized access to specific information or tools.  In a perfect world the knowledge of the existence of confidential information/tools would be unknown to all those who do not have access. When this this concept is applied within the context of an application only the authorized information/tools will be available. If we look at the sales lead management system again, leads can only be updated by originating sales members. If we look at this rule then we can say that all sales leads are confidential between the system and the sales person who entered the lead in to the system. The other sales team members would not need to know about the leads let alone need to access it. Availability within a system is the concept of authorized users being able to access the system. A real world example can be seen again from the lead management system. If that system was hosted on a web server then IP restriction can be put in place to limit access to the system based on the requesting IP address. If in this example all of the sales members where accessing the system from the 192.168.1.23 IP address then removing access from all other IPs would be need to ensure that improper access to the system is prevented while approved users can access the system from an authorized location. In essence if the requesting user is not coming from an authorized IP address then the system will appear unavailable to them. This is one way of controlling where a system is accessed. Through the years several design principles have been identified as being beneficial when integrating security aspects into a system. These principles in various combinations allow for a system to achieve the previously defined aspects of security based on generic architectural models. Security Design Principles Least Privilege Fail-Safe Defaults Economy of Mechanism Complete Mediation Open Design Separation Privilege Least Common Mechanism Psychological Acceptability Defense in Depth Least Privilege Design PrincipleThe Least Privilege design principle requires a minimalistic approach to granting user access rights to specific information and tools. Additionally, access rights should be time based as to limit resources access bound to the time needed to complete necessary tasks. The implications of granting access beyond this scope will allow for unnecessary access and the potential for data to be updated out of the approved context. The assigning of access rights will limit system damaging attacks from users whether they are intentional or not. This principle attempts to limit data changes and prevents potential damage from occurring by accident or error by reducing the amount of potential interactions with a resource. Fail-Safe Defaults Design PrincipleThe Fail-Safe Defaults design principle pertains to allowing access to resources based on granted access over access exclusion. This principle is a methodology for allowing resources to be accessed only if explicit access is granted to a user. By default users do not have access to any resources until access has been granted. This approach prevents unauthorized users from gaining access to resource until access is given. Economy of Mechanism Design PrincipleThe Economy of mechanism design principle requires that systems should be designed as simple and small as possible. Design and implementation errors result in unauthorized access to resources that would not be noticed during normal use. Complete Mediation Design PrincipleThe Complete Mediation design principle states that every access to every resource must be validated for authorization. Open Design Design PrincipleThe Open Design Design Principle is a concept that the security of a system and its algorithms should not be dependent on secrecy of its design or implementation Separation Privilege Design PrincipleThe separation privilege design principle requires that all resource approved resource access attempts be granted based on more than a single condition. For example a user should be validated for active status and has access to the specific resource. Least Common Mechanism Design PrincipleThe Least Common Mechanism design principle declares that mechanisms used to access resources should not be shared. Psychological Acceptability Design PrincipleThe Psychological Acceptability design principle refers to security mechanisms not make resources more difficult to access than if the security mechanisms were not present Defense in Depth Design PrincipleThe Defense in Depth design principle is a concept of layering resource access authorization verification in a system reduces the chance of a successful attack. This layered approach to resource authorization requires unauthorized users to circumvent each authorization attempt to gain access to a resource. When designing a system that requires meeting a security quality attribute architects need consider the scope of security needs and the minimum required security qualities. Not every system will need to use all of the basic security design principles but will use one or more in combination based on a company’s and architect’s threshold for system security because the existence of security in an application adds an additional layer to the overall system and can affect performance. That is why the definition of minimum security acceptably is need when a system is design because this quality attributes needs to be factored in with the other system quality attributes so that the system in question adheres to all qualities based on the priorities of the qualities.

• Permissions & File Structure w/ nginx & multiple sites

  - by Michael

  I am using nginx for the first time as a long time Apache user. I setup a Linode to test everything and to eventually port over my websites. Previously I had /home/user/www (wwwroot) I am looking at doing something similar with /srv/www/domain/www (wwwroot) Rather than using /srv/domain (wwwroot), the reason is many of the sites are WordPress and one of the things I do for security is to move the config file one level above wwwroot and can't have multiple configuration files from multiple domains in the same top level folder. Since I own all the sites, I wasn't going to create a user for each domain. My user is a member of www-data and was going to use 2770 for www and have domain/www for each new domain. www would be owned by group www-data. Is this the best way to handle this?

• Develop secureness first or as a later step?

  - by MattyD

  The question Do you actively think about security when coding? asks about security mindset while programming. Obviously, a developer does need to think about security while coding — SQL injection, password security, etc. However, as far as the real, fully-formed security, especially the tricky problems that may not be immediately obvious, should I be concerned with tackling these throughout the development process, or should it be a step of its own in later development? 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 wasn't built with security in mind (because it didn't need to) — therefore Flash has major security flaws at its core. I know that no one would want to actively disagree with "think security first" as a best practice, but many companies do not follow best practices. So, what is the correct approach to balance between needing to get the product done and developing it securely?

• Get rid of Vista security warning

  - by Ken

  I found this question. The question exactly matches my problem, but the solution doesn't work. In the Properties window, I see "Security: This file came from another computer and might be blocked to help protect this computer. ((Unblock))". When I click Unblock and Apply, the Security section disappears. But when I go to run it again, I still get the security warning. If I right-click and choose Properties on the exact same thing, the Security section is back, offering me the chance to Unblock it again. So unblock seems exactly as useless as the "Always ask" checkbox. Anyone seen this before? How do you really Unblock an app that Vista doesn't want to let you Unblock?

• Microsoft Security Essentials Vs. Avast Home [Free] Edition on a netbook [closed]

  - by Sarath

  I am using Avast Home Edition in my Dell Mini 10v. As you know the notebook is using an under powered processor which is not really suitable for browsing some rich internet websites. So I am in the middle of improving the performance. Will uninstalling Avast and using Microsoft Security Essentials will improve the performance? the memory usage of avast is quite low but I can't compromise security. Is Security essentials a good bet?

• Best security practice for small networks - wifi, lan,

  - by Grimlockz

  We regularly setup small networks for clients in different locations to allow them to work on different products now the question what should be the best security practice. Currently we have a wifi enabled with WPA2 and most laptops connect to this but some will connect to a cabled switch connecting to the router. We are thinking on what we should do to increase the security on our small networks - We do have have security on the laptops so you can share directly to the other persons drive by a simple Windows user account. Some suggestions are: We get a LAN switch with ACL control and mac filtering for the hard wired connections? We get acl working on the wifi via a good Cisco router? ipSec policies on all machines? IP filtering and fixed IPs? I suppose people are worried that anyone can plug into the switches and get the access to the network . Summary: Maintain a level of decent security that can be replicated easily to every setup that we do for clients

• Security Essentials for Windows 8? [closed]

  - by FiveO

  Possible Duplicate: Windows 8 and Microsoft Security Essentials Windows 8 does not seem to have the "Security Essentials" Anti-Virus like Windows 7 installed. Also the Download doesn't say Win-8 compatible. And in addition, my Soluto does not recognize any Anti-Virus program installed. Is there a Anti-Virus in Windows 8 installed by default? Or can I continue using Security Essentials? (Please no discussion about the best anti-virus software)

• How to fix some damages from site hack?

  - by Towhid

  My site had been hacked. I found vulnerability,fixed it, and removed shell scripts. But hacker had uploaded thousands of web pages on my web server. after I removed those pages I got over 4 thousand "Not Found" Pages on my site(All linked from an external free domain and host which is removed now). Also hundreds of Keywords had been added to my site. after 3 weeks I can still see keywords from removed pages on my Google Webmaster Tools. I had 1st result on google search for certain keywords but now I am on 3rd page for the same keywords. 50% of my traffic was from google which is now reduced to 6%. How can I fix both those "Not Found" pages problem and new useless keywords? and Will it be enough to get me back on first result on google? P.S: 1)Both vulnerability and uploaded files are certainly removed. 2)My site is not infected, checked on google webmaster and a few other security web scan tools. 3) all files had been uploaded on one directory so i got something like site.com/hacked/page1.html and site.com/hacked/webpage2.html

• Delphi and Microsoft ATL security issue

  - by Jens Nordenbro

  My impression is that standard Delphi uses the Win32 API. Recently Microsoft has been communicating a problem regarding ATL that requires application developers to rebuild ATL-using applications after installing an update on their machines.

• .NET Security Part 3

  - by Simon Cooper

  You write a security-related application that allows addins to be used. These addins (as dlls) can be downloaded from anywhere, and, if allowed to run full-trust, could open a security hole in your application. So you want to restrict what the addin dlls can do, using a sandboxed appdomain, as explained in my previous posts. But there needs to be an interaction between the code running in the sandbox and the code that created the sandbox, so the sandboxed code can control or react to things that happen in the controlling application. Sandboxed code needs to be able to call code outside the sandbox. Now, there are various methods of allowing cross-appdomain calls, the two main ones being .NET Remoting with MarshalByRefObject, and WCF named pipes. I’m not going to cover the details of setting up such mechanisms here, or which you should choose for your specific situation; there are plenty of blogs and tutorials covering such issues elsewhere. What I’m going to concentrate on here is the more general problem of running fully-trusted code within a sandbox, which is required in most methods of app-domain communication and control. Defining assemblies as fully-trusted In my last post, I mentioned that when you create a sandboxed appdomain, you can pass in a list of assembly strongnames that run as full-trust within the appdomain: // get the Assembly object for the assembly Assembly assemblyWithApi = ... // get the StrongName from the assembly's collection of evidence StrongName apiStrongName = assemblyWithApi.Evidence.GetHostEvidence<StrongName>(); // create the sandbox AppDomain sandbox = AppDomain.CreateDomain( "Sandbox", null, appDomainSetup, restrictedPerms, apiStrongName); Any assembly that is loaded into the sandbox with a strong name the same as one in the list of full-trust strong names is unconditionally given full-trust permissions within the sandbox, irregardless of permissions and sandbox setup. This is very powerful! You should only use this for assemblies that you trust as much as the code creating the sandbox. So now you have a class that you want the sandboxed code to call: // within assemblyWithApi public class MyApi { public static void MethodToDoThings() { ... } } // within the sandboxed dll public class UntrustedSandboxedClass { public void DodgyMethod() { ... MyApi.MethodToDoThings(); ... } } However, if you try to do this, you get quite an ugly exception: MethodAccessException: Attempt by security transparent method ‘UntrustedSandboxedClass.DodgyMethod()’ to access security critical method ‘MyApi.MethodToDoThings()’ failed. Security transparency, which I covered in my first post in the series, has entered the picture. Partially-trusted code runs at the Transparent security level, fully-trusted code runs at the Critical security level, and Transparent code cannot under any circumstances call Critical code. Security transparency and AllowPartiallyTrustedCallersAttribute So the solution is easy, right? Make MethodToDoThings SafeCritical, then the transparent code running in the sandbox can call the api: [SecuritySafeCritical] public static void MethodToDoThings() { ... } However, this doesn’t solve the problem. When you try again, exactly the same exception is thrown; MethodToDoThings is still running as Critical code. What’s going on? By default, a fully-trusted assembly always runs Critical code, irregardless of any security attributes on its types and methods. This is because it may not have been designed in a secure way when called from transparent code – as we’ll see in the next post, it is easy to open a security hole despite all the security protections .NET 4 offers. When exposing an assembly to be called from partially-trusted code, the entire assembly needs a security audit to decide what should be transparent, safe critical, or critical, and close any potential security holes. This is where AllowPartiallyTrustedCallersAttribute (APTCA) comes in. Without this attribute, fully-trusted assemblies run Critical code, and partially-trusted assemblies run Transparent code. When this attribute is applied to an assembly, it confirms that the assembly has had a full security audit, and it is safe to be called from untrusted code. All code in that assembly runs as Transparent, but SecurityCriticalAttribute and SecuritySafeCriticalAttribute can be applied to individual types and methods to make those run at the Critical or SafeCritical levels, with all the restrictions that entails. So, to allow the sandboxed assembly to call the full-trust API assembly, simply add APCTA to the API assembly: [assembly: AllowPartiallyTrustedCallers] and everything works as you expect. The sandboxed dll can call your API dll, and from there communicate with the rest of the application. Conclusion That’s the basics of running a full-trust assembly in a sandboxed appdomain, and allowing a sandboxed assembly to access it. The key is AllowPartiallyTrustedCallersAttribute, which is what lets partially-trusted code call a fully-trusted assembly. However, an assembly with APTCA applied to it means that you have run a full security audit of every type and member in the assembly. If you don’t, then you could inadvertently open a security hole. I’ll be looking at ways this can happen in my next post.

• Security Controls on data for P6 Analytics

  - by Jeffrey McDaniel

  The Star database and P6 Analytics calculates security based on P6 security using OBS, global, project, cost, and resource security considerations. If there is some concern that users are not seeing expected data in P6 Analytics here are some areas to review: 1. Determining if a user has cost security is based on the Project level security privileges - either View Project Costs/Financials or Edit EPS Financials. If expecting to see costs make sure one of these permissions are allocated.  2. User must have OBS access on a Project. Not WBS level. WBS level security is not supported. Make sure user has OBS on project level.  3. Resource Access is determined by what is granted in P6. Verify the resource access granted to this user in P6. Resource security is hierarchical. Project access will override Resource access based on the way security policies are applied. 4. Module access must be given to a P6 user for that user to come over into Star/P6 Analytics. For earlier version of RDB there was a report_user_flag on the Users table. This flag field is no longer used after P6 Reporting Database 2.1. 5. For P6 Reporting Database versions 2.2 and higher, the Extended Schema Security service must be run to calculate all security. Any changes to privileges or security this service must be rerun before any ETL. 6. In P6 Analytics 2.0 or higher, a Weblogic user must exist that matches the P6 username. For example user Tim must exist in P6 and Weblogic users for Tim to be able to log into P6 Analytics and access data based on  P6 security.  In earlier versions the username needed to exist in RPD. 7. Cache in OBI is another area that can sometimes make it seem a user isn't seeing the data they expect. While cache can be beneficial for performance in OBI. If the data is outdated it can retrieve older, stale data. Clearing or turning off cache when rerunning a query can determine if the returned result set was from cache or from the database.

• Spring Security: how to implement Brute Force Detection (BFD)?

  - by Kdeveloper

  My web applications security is handled by Spring Security 3.02 but I can't find any out of the box support for Brute Force Detection. I would like to implement some application level BFD protection. For example by storing failed login attempt per user in the database (JPA). The attacked user accounts could then get a lockout period or a forced account re-activation by e-mail. What's the best way to implement this with Spring Security? Does any body have example code or best practices on this?

• Reality behind wireless security - the weakness of encrypting

  - by Cawas

  I welcome better key-wording here, both on tags and title, and I'll add more links as soon as possible. For some years I'm trying to conceive a wireless environment that I'd setup anywhere and advise for everyone, including from big enterprises to small home networks of 1 machine. I've always had the feeling using any kind of the so called "wireless security" methods is actually a bad design. I'm talking mostly about encrypting and pass-phrasing (which are actually two different concepts), since I won't even considering hiding SSID and mac filtering. I understand it's a natural way of thinking. With cable networking nobody can access the network unless they have access to the physical cable, so you're "secure" in the physical way. In a way, encrypting is for wireless what walling (building walls) is for the cables. And giving pass-phrases is adding a door with a key. But the cabling without encryption is also insecure. Someone just need to plugin and get your data! And while I can see the use for encrypting data, I don't think it's a security measure in wireless networks. As I said elsewhere, I believe we should encrypt only sensitive data regardless of wires. And passwords should be added to the users, always, not to wifi. For securing files, truly, best solution is backup. Sure all that doesn't happen that often, but I won't consider the most situations where people just don't care. I think there are enough situations where people actually care on using passwords on their OS users, so let's go with that in mind. For being able to break the walls or the door someone will need proper equipment such as a hammer or a master key of some kind. Same is true for breaking the wireless walls in the analogy. But, I'd say true data security is at another place. I keep promoting the Fonera concept as an instance. It opens up a free wifi port, if you choose so, and anyone can connect to the internet through that, without having any access to your LAN. It also uses a QoS which will never let your bandwidth drop from that public usage. That's security, and it's open. And who doesn't want to be able to use internet freely anywhere you can find wifi spots? I have 3G myself, but that's beyond the point here. If I have a wifi at home I want to let people freely use it for internet as to not be an hypocrite and even guests can easily access my files, just for reading access, so I don't need to keep setting up encryption and pass-phrases that are not whole compatible. I'll probably be bashed for promoting the non-usage of WPA 2 with AES or whatever, but I wanted to know from more experienced (super) users out there: what do you think? Is there really a need for encryption to have true wireless security?

• Is a security seal or EV SLL more important?

  - by Guy

  Does anybody know of a survey or study that compares site visitor attitudes/perceptions to security between an EV SSL cert and a security seal? The EV SSL cert will show up green in the URL (like a bank) and the security seal is usually in the footer and says something like "secured by" or "hacker proof" or "website protection" I'm looking for evidence that if you could only chose one, which would it be?

• Physical Directories vs. MVC View Paths

  - by Rick Strahl

  This post falls into the bucket of operator error on my part, but I want to share this anyway because it describes an issue that has bitten me a few times now and writing it down might keep it a little stronger in my mind. I've been working on an MVC project the last few days, and at the end of a long day I accidentally moved one of my View folders from the MVC Root Folder to the project root. It must have been at the very end of the day before shutting down because tests and manual site navigation worked fine just before I quit for the night. I checked in changes and called it a night. Next day I came back, started running the app and had a lot of breaks with certain views. Oddly custom routes to these controllers/views worked, but stock /{controller}/{action} routes would not. After a bit of spelunking I realized that "Hey one of my View Folders is missing", which made some sense given the error messages I got. I looked in the recycle bin - nothing there, so rather than try to figure out what the hell happened, just restored from my last SVN checkin. At this point the folders are back… but… view access  still ends up breaking for this set of views. Specifically I'm getting the Yellow Screen of Death with: CS0103: The name 'model' does not exist in the current context Here's the full error: Server Error in '/ClassifiedsWeb' Application. Compilation ErrorDescription: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.Compiler Error Message: CS0103: The name 'model' does not exist in the current contextSource Error: Line 1: @model ClassifiedsWeb.EntryViewModel Line 2: @{ Line 3: ViewBag.Title = Model.Entry.Title + " - " + ClassifiedsBusiness.App.Configuration.ApplicationName; Source File: c:\Projects2010\Clients\GorgeNet\Classifieds\ClassifiedsWeb\Classifieds\Show.cshtml    Line: 1 Compiler Warning Messages: Show Detailed Compiler Output: Show Complete Compilation Source: Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.272 Here's what's really odd about this error: The views now do exist in the /Views/Classifieds folder of the project, but it appears like MVC is trying to execute the views directly. This is getting pretty weird, man! So I hook up some break points in my controllers to see if my controller actions are getting fired - and sure enough it turns out they are not - but only for those views that were previously 'lost' and then restored from SVN. WTF? At this point I'm thinking that I must have messed up one of the config files, but after some more spelunking and realizing that all the other Controller views work, I give up that idea. Config's gotta be OK if other controllers and views are working. Root Folders and MVC Views don't mix As I mentioned the problem was the fact that I inadvertantly managed to drag my View folder to the root folder of the project. Here's what this looks like in my FUBAR'd project structure after I copied back /Views/Classifieds folder from SVN: There's the actual root folder in the /Views folder and the accidental copy that sits of the root. I of course did not notice the /Classifieds folder at the root because it was excluded and didn't show up in the project. Now, before you call me a complete idiot remember that this happened by accident - an accidental drag probably just before shutting down for the night. :-) So why does this break? MVC should be happy with views in the /Views/Classifieds folder right? While MVC might be happy, IIS is not. The fact that there is a physical folder on disk takes precedence over MVC's routing. In other words if a URL exists that matches a route the pysical path is accessed first. What happens here is that essentially IIS is trying to execute the .cshtml pages directly without ever routing to the Controller methods. In the error page I showed above my clue should have been that the view was served as: c:\Projects2010\Clients\GorgeNet\Classifieds\ClassifiedsWeb\Classifieds\Show.cshtml rather than c:\Projects2010\Clients\GorgeNet\Classifieds\ClassifiedsWeb\Views\Classifieds\Show.cshtml But of course I didn't notice that right away, just skimming to the end and looking at the file name. The reason that /classifieds/list actually fires that file is that the ASP.NET Web Pages engine looks for physical files on disk that match a path. IOW, when calling Web Pages you drop the .cshtml off the Razor page and IIS will serve that just fine. So: /classifieds/list looks and tries to find /classifieds/list.cshtml and executes that script. And that is exactly what's happening. Web Pages is trying to execute the .cshtml file and it fails because Web Pages knows nothing about the @model tag which is an MVC specific template extension. This is why my breakpoints in the controller methods didn't fire and it also explains why the error mentions that the @model key word is invalid (@model is an MVC provided template enhancement to the Razor Engine). The solution of course is super simple: Delete the accidentally created root folder and the problem is solved. Routing and Physical Paths I've run into problems with this before actually. In the past I've had a number of applications that had a physical /Admin folder which also would conflict with an MVC Admin controller. More than once I ended up wondering why the index route (/Admin/) was not working properly. If a physical /Admin folder exists /Admin will not route to the Index action (or whatever default action you have set up, but instead try to list the directory or show the default document in the folder. The only way to force the index page through MVC is to explicitly use /Admin/Index. Makes perfect sense once you realize the physical folder is there, but that's easy to forget in an MVC application. As you might imagine after a few times of running into this I gave up on the Admin folder and moved everything into MVC views to handle those operations. Still it's one of those things that can easily bite you, because the behavior and error messages seem to point at completely different  problems. Moral of the story is: If you see routing problems where routes are not reaching obvious controller methods, always check to make sure there's isn't a physical path being mapped by IIS instead. That way you won't feel stupid like I did after trying a million things for about an hour before discovering my sloppy mousing behavior :-)© Rick Strahl, West Wind Technologies, 2005-2012Posted in MVC   IIS7   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); })();

• GlassFish v3: Security related updates + Repository/Publisher?

  - by chris_l

  I've used GlassFish v3.0 as my main development application server for a few weeks now. Now that I want to install it on my VPS, I'd like to get the latest security updates, because Glassfish v3 Release 3.0 (Open Source Edition or not) is already a few months old, and v3.1 is only available as "early access" nightlies (see https://glassfish.dev.java.net/public/downloadsindex.html). GlassFish offers an update mechanism (via pkg or updateTool), but when I simply try to get the latest updates (pkg image-update), it finds nothing. However, when I change the preferred publisher to dev.glassfish.org, I get a list with lots of updates. The interesting thing is, that I haven't been able to find any description about the contents of the diverse publishers/repositories (release, stable, contrib and dev) anywhere on the web, most importantly answering the question: Am I supposed to use the dev repository for security updates, or does it contain unstable updates? (The name suggests unstable updates, but the version numbers, like "3.0.1,0-11:20100331T082227Z" leave me guessing. The build is more than a week old, so it's obviously not "nightly" or "weekly", but what is it?) Where do I get security updates from then? Or are there simply no security updates yet? Asking on the GlassFish forum resulted in 56 views, but 0 answers.
