SQL> Behavior of sys auditing is defined by other parameters (audit_file_dest,audit_sys_operations) and is not a subject of this post. This is, I believe, an answer to your question. Simple recording of who logged in, when was it done and from where was it done is called auditing and is available as of version 10.2. It might be available even in the earlier versions. Consult the DBA guide, Concepts and SQL Reference, it's probably there.
