Audit trail

The merging unit offers a large set of event-logging functions. Critical system and
merging unit security-related events are logged to a separate nonvolatile audit trail for
the administrator.
Audit trail is a chronological record of system activities that allows the reconstruction
and examination of the sequence of system and security-related events and changes in
the merging unit. Both audit trail events and process related events can be examined
and analyzed in a consistent method with the help of Event List in WHMI and Event
Viewer in PCM600.
The merging unit stores 2048 audit trail events to the nonvolatile audit trail.
Additionally, 1024 process events are stored in a nonvolatile event list. Both the audit
trail and event list work according to the FIFO principle. Nonvolatile memory is based
on a memory type which does not need battery backup nor regular component change
to maintain the memory storage.
Audit trail events related to user authorization (login, logout, violation remote and
violation local) are defined according to the selected set of requirements from IEEE
1686. The logging is based on predefined user names or user categories. The user audit
trail events are accessible with IEC 61850-8-1, PCM600 and WHMI.
