SSL Medium Strength Cipher Suites Supported

Nessus Output


The remote host supports the use of SSL ciphers that offer medium strength encryption. 
Nessus regards medium strength as any encryption that uses key lengths at least 56 bits and less than 112 bits, or else that uses the 3DES encryption suite.

Note that it is considerably easier to circumvent medium strength encryption if the attacker is on the same physical network.


Reconfigure the affected application if possible to avoid use of medium strength ciphers.

Use IIS Crypto

IIS Crypto is a free tool that gives administrators the ability to enable or disable protocols, ciphers, hashes and key exchange algorithms on Windows Server 2008, 2012 and 2016. It also lets you reorder SSL/TLS cipher suites offered by IIS, implement best practices with a single click, create custom templates and test your website.
