It tests for vulnerabilities, ciphers, protocols etc. For more information about the TLS cipher suites, see the documentation for the Enable-TlsCipherSuite cmdlet or type Get-Help Enable-TlsCipherSuite. SSL/TLS is not in play here so I'm talking about RDP encryption. 2. Vulnerability Scanners, in addition to performing service discovery, may include checks against weak ciphers (for example, the Nessus scanner has the capability of checking SSL services on arbitrary ports, and will report weak ciphers). The following are the switches for the command line version of IIS Crypto. \n4.

To add cipher suites, either deploy a group policy or use the TLS cmdlets: Prior to Windows 10, cipher suite strings were appended with the elliptic curve to determine the curve priority. Note that these classes are part of the Sun JSSE implementation and not part of the public Java API. I recommend using the list put together by Steve Gibson over at GRC.com: https://www.grc.com/miscfiles/SChannel_Cipher_Suites.txt.
