FTD/FMC 6.6.5 : SSL Policy Exception for MS Windows Update

Erwan LE BIHAN

Hi.

I'm looking for any best practices for implementing a SSL Policy Exception Rule.

LAN -> Internet is using a generic Decrypt-Resign all HTTPS sessions.

And i'm trying to add an exception as Windows update clients and WSUS are both complaining about bad certificates.

Should I use:

- Source Zone, Dest Zone, Source NetWork + Application = Microsoft Update + Dest Port=HTTPS or

- Source Zone, Dest Zone, Source Network + Port=HTTPS, SSL Subject DN=CN_update.microsoft.com & CN_.update.microsoft.com

 

Or another solution ?

 

Please advise & Thanks in advance
