Auditd

Reloading

Before reloading remember to regnerate “/etc/audit/audit.rules” by running “augenrules” first:

 augenrules && systemctl restart auditd

Rule Examples

-D                                      # Clear all rules

-a exit,always -F msgtype=USER_ERR      # All login errors

Manually adding rules

auditctl -a always,exit -F arch=b64 -F pid=<pid> -S open -k <trace name>

Querying traces

ausearch -k <trace name>

Connecting to syslog

This is done using an audisp plugin, which is disabled per default. Enable it setting “active=yes” in /etc/audisp/plugins.d/syslog.conf and reload auditd.
