comment Totally secure public key distrubition
You just say "a CA" can be subverted are you ruling out ALL solutions that involve a 3rd party (for example a "Web of Trust", or a private CA)?

comment Do the Windows shared source files compile into the same binaries as the retail version?
One big thing that will not be in ANY code sharing database will be the private keys to sign the files. Most of the "important" DLL's in windows (ntdll.dll, clfs.dll, ect...) are all digitally signed and there is no way to re-create that without the keys from Microsoft.

comment How do I mitigate a MITM on https?
I find that not as likely (I don't see a reason they would store the start time) however I very easily could see a math bug for calculating the correct time zone offset.

I think you where close, Look at the "Not valid before" time, I think he connected too early (or at least his machine thought it was too early) for the certificate to be valid.

You may want to add something about Strict Transport Security as a countermeasure too.

comment Can I avoid DNS spoofing by typing the IP address?
A good example of this, go ping security.stackexcange.com and you will likely get the ip 198.252.206.16, but if you visit that IP, you do not get this website.

comment Why can a Tor exit node decrypt data, but not the entry node?
@bonsaiviking Ahh, I see. You are the first person ever to be able to explain that. So its Me<--(TCP connection 1)-->Tor Entry point<--(Tor Protocol Stream)-->Tor Server<--(Tor Protocol Stream)-->Tor Server<--(Tor Protocol Stream)->Tor Exit Point<--(TCP connection 2)-->Destination Server So I only have a TCP connection to the entry point and the final destination only has a TCP connection to the exit point.

Last question, is this the domain controller or just a server on the domain.

comment Recover Server 2008 R2 Domain Admin Password
Must the password be recovered or is resetting the password without ever learning what the old value was acceptable (I doubt it can be done due to your bitlocker use, but I just want the clarification in case someone besides me knows a way)

comment How secure is the Windows event log, and how is it secured?
If a machine is compromised there is no way to solve the problem locally. "If your machine can do it, then the malware can do it too". The only way to solve the the problems is store the logs in a way that the machine that is creating the log entry can not edit the log itself. That may be by using WORM media or by using a 2nd machine and doing log shipping. Now if the 2nd machine gets infected too all bets are off again as the malware can just edit the logs again.

comment How secure is the Windows event log, and how is it secured?
Iszi told you already. Windows file permissions on the %SystemRoot%\System32\Winevt\Logs\ directory is the only security measure that is implemented out of the box. There is no tamper-resistance mechanisms in place other than permission restrictions. However Windows has made it easy to do log shipping as that is the "recommended" way of providing tamper-resistance.

comment Why can a Tor exit node decrypt data, but not the entry node?
I agree with Petey B, the return path of the TCP connection is kind of "hand waved" away. Could you update your answer to give a better explanation of how a reply packet (even something as simple as the SYN-ACK packet of the 3 way handshake) on the TCP connection is sent back through the tor network and get to the original sender?

comment CTRL+ALT+DEL Login - Rationale behind it?
@D3C4FF Just because you can't intercept the message does not mean you can't tell windows what to do when it receives the message. The important phrase from Thomas' post is "without needing administrative rights"
