Re: [Full-disclosure] Restricting access to SVCCTL named pipe on Windows

[Geof <geofgeof@xxxxxxxxx>]

Well, the problem is that I need to give network share access, so I cannot
block port 445.

What I want to do is to protect my server if someone found a local admin
account from installating software on it through svcctl access. For example,
if someone found a local admin account, it cant restart remote registry
access, then so re-enable administrative shares, and so on...

Sure, i can enforce all the local accounts, but in an "in-depth defense"
it's not enought
