Verify the audit tools file permissions. The list of files should minimally include the following: audevent - Change/display event/system call status. audfilter - Load/clear/display the audit filtering policy. auditdp - Selectively read/write and convert/format the audit data. audisp - Display audit records. audomon - Audit file monitoring and size parameter setpoints. audsys - Start/stop auditing; set/display the audit file or directory information. userdbset - Select user to be audited. # ls -lL /usr/sbin/aud* /usr/sbin/userdb* If any audit tool file permissions include a “+”, this is a finding.
