20.8 Audit Trail

The Cisco ONS 15454 maintains a Telcordia GR-839-CORE-compliant audit trail log that resides on the
TCC2. This record shows who has accessed the system and what operations were performed during a
given period of time. The log includes authorized Cisco logins and logouts using the operating system
command line interface, CTC, and TL1; the log also includes FTP actions, circuit creation/deletion, and
user/system generated actions.
Event monitoring is also recorded in the audit log. An event is defined as the change in status of an
element within the network. External events, internal events, attribute changes, and software
upload/download activities are recorded in the audit trail.
