Cipher suites - IIS Crypto

Working on the following finding: ssl-static-key-ciphers and I’ve cleared them in IIS Crypto and rebooted / rescanned with InsightVM but they’re still showing. They’re not showing in the registry on the system. Has anyone else run into this?

We had to go in with a powershell script that removes the Cipher Suites explicitly, using the Disable-TLSCipherSuite cmdlet.

When I run:

(Get-ItemProperty -Path "HKLM:\SOFTWARE\Policies\Microsoft\Cryptography\Configuration\SSL\00010002").Functions

It doesn’t show the ones I unchecked in IIS Crypto so I’m puzzled.

I’ve been in situations with InsightVM where we’ve remediated a finding by shutting down the unnecessary service/blocking the port/etc. so the scanner can no longer “see” whether the vulnerability is still present. The workaround in those cases has been to delete the asset and let it be added back when it is next scanned.
