Microsoft Releases a TLS 1.1 Fix Tool for Windows

Microsoft has released a security advisory relating to the SSL/TLS vulnerability previously discussed.   Included in the advisory are a workaround and a tool that can implement a fix on Windows 7 and Windows Server 2008 R2 systems.

If you're using a version of Windows prior to version 7 or Server 2008 R2, your system doesn't even support TLS 1.1.   Your only hope is that server admins fix the SSL/TLS problem on their web servers.

Interestingly enough, the RC4 cipher suite is unaffected.   Only encryption based on CBC (cipher block chaining) is affected.   RC4 is a streaming cipher, which is not affected.

Policies and Controls are King in the IT Security world

I came across an article by Roger Grimes over at Infoworld on how security policies and controls are the real power when it comes to IT security. Roger mentions the SANS 20 Critical Security Controls for Effective Cyber Defence , which are a great read for anyone looking at updating or auditing your policies for completeness.

Fun Little Earthquake

It's 1:45pm EST in Ottawa, Ontario, Canada. We just had an earthquake.  Not strong enough to damage anything, but enough that I watched people run out of buildings. What a fun Wednesday.

Error 217 - Error creating product object on Domino 64 bit

I'd like to share something with you.   An error that you'll get if you are trying to use ODBC with Domino 8.5.1 64bit. It starts out with an agent error of Error 217.  The text of the error is "Error creating product object" You can read about it here on the Notes/Domino forum . You can find the solution here as well . I guess I'm now waiting for Domino 8.5.2 for a solution for this.   It would have been nice to have had this in the release notes.  It would have help me greatly.
