• How can I configure apache2 to use a non - exportable ssl certificate managed by windows?

  - by Samuel Rossille

  On Windows Server 2008 R2, my IT administrator has installed a certificate using the windows certificate management tool. The certificate is for *.thedomain.com. He set it up as not exportable for security reasons: I'm not suposed to be able to put my hands on the certificate. This configuration would allow me to use the certificate with microsoft products, but not to go away with the certificate. Q: It there a way to configure Apache 2 to use this certificate "the windows way"?

  I am trying to figure out how to configure IAM in Amazon AWS to use Windows Azure Active Directory.

• Why won't IE let users login to a website unless in In Private mode?

  - by Richard Fawcett

  I'm not entirely sure this belongs on SuperUser.com. I also considered ServerFault.com and StackOverflow.com, but on balance, I think it should belong here? We host a website which has the same code responding to multiple domain names. On 28th December (without any changes deployed to the website) a percentage of users suddenly could not login, and the blank login page was just rendered again even when the correct credentials were entered. The issue is still ongoing. After remote controlling an affected user's PC, we've found the following: The issue affects Internet Explorer 9. The user can login from the same machine on Chrome. The user can login from an In Private browser session using IE9. The user can login if the website is added to the Trusted Sites security zone. The user can NOT login from an IE session in safe mode (started with iexplore -extoff). Only one hostname that the website responds to prevents login, the same user account on the other hostname works fine (note that this is identical code and database running server side), even though that site is not in trusted sites zone. Series of HTTP requests in the failure case: GET request to protected page, returns a 302 FOUND response to login page. GET request to login page. POST to login page, containing credentials, returns redirect to protected page. GET request to protected page... for some reason auth fails and browser is redirected to login page, as in step 1. Other information: Operating system is Windows 7 Ultimate Edition. AV system is AVG Internet Security 2012. I can think of lots of things that could be going wrong, but in every case, one of the findings above is incompatible with the theory. Any ideas what is causing login to fail? Update 06-Jan-2012 Enhanced logging has shown that the .ASPXAUTH cookie is being set in step 3. Its expiry date is 28 days in the future, its path is /, the domain is mysite.com, and its value is an encrypted forms ticket, as expected. However, the cookie is not being received by the web server during step 4. Other cookies are being presented to the server during step 4, it's just this one that is missing. I've seen that cookies are usually set with a domain starting with a period, but mine isn't. Should it be .mysite.com instead of mysite.com? However, if this was wrong, it would presumably affect all users?

• Is there anything wrong with disabling Teredo?

  - by Wayne Hartman

  Today while doing some routine maintenance I discovered that my internet-connected network adapter was using a 6to4 tunnel to connect to my ISP. Some self-eduction on Teredo seemed to indicate quite a few potential security vulnerabilities with using the protocol. I have disabled my network adapter from using Teredo and it doesn't seem to impact my gateway in any way. Is there anything I am missing that should encourage me to turn it back on?

• How Do I Restrict Views of a Custom List by Group in Sharepoint 2007?

  - by Crash893

  I'm pretty new to Sharepoint and what I would like to do is create a huge master list of all our employees and then make different "views" on that person depending on the persons group For example: A new employee might have Salary info Security info Personnel info Contract info I would like to have all that in one row (per employee) but then when someone from the hr group logs in they can only see Personnel and Salary or something like that. If that is not an option is there a way to link tables across different lists?

• What's the best scenario for using a wireless router with Comcast Business Class

  - by Buck

  Just had Comcast Business Class internet installed (usage details at bottom of post). During the call to order I asked about the hardware they'd be providing and was told it was a docsis 3 modem that I'd have to pay $7.00/month for. Figuring I'd have to buy a router anyway, I decided to get my own modem - a Surfboard SB6121 Docsis 3. I called in to tech support to ask some questions and learned that the modem they would have provided DID have a router built in. It's an SMCD3G-CCR. It's not wireless (we need wireless). The guy explained that it was better to have their hardware here because if there's a problem with our service and we're using our own hardware, chances are they'll blame it on our hardware and do nothing since they don't support it. He explained that I could still hang my own wireless router off their modem/router and if we ever had any service problems, we'd be able to plug directly into their hardware and they'd be able to tell where the problem is and they wouldn't be able to pawn it off onto "customer provided equipment". That all said, a few questions: 1. Am I better off returning my Surfboard modem and getting the Comcast one? If I get a wireless router and plug into one of the ethernet ports of the Comcast device, should I NOT plug anything else into the Comcast device since it would be a different network from anything connecting via the wireless router? Is that correct? Given that I know VERY LITTLE about networking and setting up hardware like this... since I need wireless and will HAVE to get a wireless router to work with this Comcast device, do I need to do anything with the settings of the Comcast device? Do I use security on the Comcast device or the wireless router or both? Any suggestions or anything I need to think about, given this scenario, in order to use a business-type voip service like RingCentral or Jive or Nextiva? Any recommendations on a wireless router for this scenario? We are running 2 PCs (possibly 3-4 in the future) - could be wired for the time being if needed but would prefer wireless; would like to have a networked hard drive and a networked printer; NEED business-type VOIP service asap for 2 phone lines. Would like to hook up some IP cameras at some point (but not the kind that require static IPs since I don't have one nor do I plan to pay Comcast another $15/month for one). I don't have or plan to have any type of web servers or anything like that. Want to use WPA or WPA2 security and take advantage of the NAT feature of the router for additional protection (that's the extent of my networking knowledge).

• Which service should I make mine dependant on ?

  - by Retrocoder

  I want to add a dependency to my service so that it only tries to start after most of the Windows services have started. Can anyone recommend such a service that is unlikely to have been disabled for security reasons on corporate sites. As my service needs the networking services up and running I want to make sure mine starts after these. This service may also be deployed in non-corporate environments so I’m looking for a suitable service that is unlikely to have been disabled by the end user.

• Use-cases for assigning multiple IP addresses to 1 NIC

  - by Harry

  What would be some of major use-cases in which you would want to assign multiple IP addresses to your NIC? Knowing of any standard/well-known 'gotchas' associated with each use-case would also be helpful. For example, I heard someone saying that a user with access to such a machine will automatically get access to both networks, which could be a security issue. You can assume a Linux-based environment.

• Windows powering off after "preparing your desktop" stage.

  - by Jack

  Windows 7 64 bit. The only recent change was I installed two updates for MS Office, and a cumulative security update for IE. As soon as I choose a user and login, after loading my user profile it states the preparing your desktop message, and then powers off. I have used DaRT to check the event log, but nothing is recorded. Ideas?

• "log on as a batch job" user rights removed by what GPO?

  - by LarsH

  I am not much of a server administrator, but get my feet wet when I have to. Right now I'm running some COTS software on a Windows 2008 Server machine. The software installer creates a few user accounts for running its processes, and then gives those users the right to "log on as a batch job". Every so often (e.g. yesterday at 2:52pm and this morning at 7:50am), those rights disappear. The software then stops working. I can verify that the user rights are gone by using secedit /export /cfg e:\temp\uraExp.inf /areas USER_RIGHTS and I have a script that does this every 30 seconds and logs the results with a timestamp, so I know when the rights disappear. What I see from the export is that in the "good" state, i.e. after I install the software and it's working correctly, the line for SeBatchLogonRight from the secedit export includes the user accounts created by the software. But every few hours (sometimes more), those user accounts are removed from that line. The same thing can be seen by using the GUI tool Local Security Policy > Security Settings > Local Policies > User Rights Assignment > Log on as a batch job: in the "good" state, that policy includes the needed user accounts, and in the bad state, the policy does not. Based on the above-mentioned logging script and the timestamps at which the user rights are being removed, I can see clearly that some GPOs are causing the change. The GPO Operational log shows GPOs being processed at exactly the right times. E.g.: Starting Registry Extension Processing. List of applicable GPOs: (Changes were detected.) Local Group Policy I have run GPOs on demand using gpupdate /force, and was able to verify that this caused the User Rights to be removed. We have looked over local group policies till our eyes are crossed, trying to figure out which one might be stripping these User Rights to "log on as a batch job." We have not configured any local group policies on this machine, that we know of; so is there a default local group policy that might typically do such a thing? Are there typical domain policies that would do this? I have been working with our IT staff colleagues to troubleshoot the problem, but none of them are really GPO experts... They wear many hats, and they do what they need to do in order to keep most things running. Any suggestions would be greatly appreciated!

• Improved ACL editor for Windows file permissions

  - by Myrddin Emrys

  I have recently been doing a lot of updates to our network drive permissions... such as consolidating direct user permissions into group permissions. The built-in ACL editor (Advanced Security Settings dialog) is adequate, but its limitations are frustrating, particularly that it cannot be resized and you cannot look at the list of existing entries at the same time as you are adding a new entry. Is there an improved ACL editor that can be downloaded to supplement the default one?

• backup aws ec2 to separate account

  - by Paul de Goede

  I want to backup my AWS snapshots to a completely separate AWS account for additional security (if my AWS credentials were acquired someone could delete all my snapshots and volumes). But I'm a bit stumped on how to do this. There doesn't seem to be a way to store a volume or snapshot in S3 such that another user could access that data in s3 and store it in a separate AWS account. Does anyone have any suggestions on how to acheive this? Thanks

• How is the filesystem of Wikipedia designed?

  - by Heo

  I read about FHS, and I started to consider the file system of wikipedia. On the one hand, I feel it is a security risk to let everyone know it. On the other hand, it is necessary for developers. For example, is there some rule to know where are all sitemaps and their indices located? So: How is the file system of Wikipedia designed?

• How to implement a secure authentication over HTTP?

  - by Zagorax

  I know that we have HTTPS, but I would like to know if there's an algorithm/approach/strategy that grants a reasonable security level without using SSL. I have read many solution on the internet. Most of them are based on adding some time metadata to the hashes, but it needs that both server and client has the time set equal. Moreover, it seems to me that none of this solution could prevent a man in the middle attack.

• IIS 7 Web service access

  - by Aharon Manne

  I am trying to debug a simple web service. I have IIS 7 installed on my development machine (Windows 7), and have installed the web service. I can access it from my development machine, but not from any other machine in the local network.I opened the firewall to HTTP access, and I can access the default website from other machines, so it is not the firewall.What security settings should I look at to try to allow devices on the LAN to access the web service?
