Security scan - TLS Version 1.0 and 1.1 Protocol Detection on Mediation Manager systems
Release: 20.2.8 and earlier
Security is controlled by the java.security file and its settings within. This file exists within the java release that was provided for CAMM to use. This file contains a parameter called jdk.tls.disabledAlgorithms which provides a place to restrict Java from utilizing various algorithms, like SSLv3 and TLS1.0/1.1.
An example value of this parameter to restrict Java from using Sslv3, TLS1.0 and TLS1.1
jdk.tls.disabledAlgorithms=SSLv3, RC4, DES, TLSv1, TLSv1.1, MD5withRSA, DH keySize < 1024
Once this update has been completed, Mediation Manager services need to be restarted via the stopall and startall scripts.
This will need to be accomplished for every new Java release that does not come configured in this way out of the box.
