system_traces is for query tracing, which is for diagnosing performance problems, not logging activity.
Cassandra is designed to allow you to write your own Authenticator pretty easily. You can just subclass PasswordAuthenticator and add logging where desired. Compile that into a jar, put it in the lib/ directory for Cassandra, and change cassandra.yaml to use that class.
