Communications security (COMSEC) encompasses the policies, procedures and technologies used to protect information in transmission, whether that information be generated by computers or not. It complements computer security]], which protects information in computers. Many of the same criteria of information assurance]] apply, but not all, and there are some aspects unique to COMSEC.
