logcheck - 1.4.3 main

Logcheck analyses the system log for unuexpected entries that could
indicate problems or security issues.
.
Log entries in the system log (produced by systemd-journald, rsyslog
or another system-log-dameon) are checked against a customisable
database of regular expressions (such as that provided by the
logcheck-database package) to identify routine messages: anything
that does not identified as routine is reported to the system
administrator.
.
Logcheck was originally part of the Abacus Project of security tools,
but has been rewritten.
