Security

Security has been enhanced through support for the new AES ciphers and higher encryption keylengths. You can also restrict the minimum encryption level for negotiations between clients and CICS® by editing the default values of cipher suites that are used in SSL connections.

The ENCRYPTION system initialization parameter default value is now STRONG, raising the level of security in CICS when using SSL.

The security category for the CCRL transaction is category 2.
