To audit user creation actions, first, add a watch to the /etc/passwd file to track write and attribute change access, and add a custom key to log all messages (this custom key is useful to filter log messages): $ sudo auditctl -w /etc/passwd -p wa -k user-modify The syntax to define watch rules is: auditctl -w path_to_file -p permissions -k key_name ![]() ![]() This rule tracks whether a file or directory is triggered by certain types of access, including read, write, execute, and attribute changes. Ordering is important for rules to function as intended, and the service works on a first-match-win basis. With the auditctl tool, you can add auditing rules on any system call you want. The only reason to use the service command instead of systemctl is to record a user ID (UID) value properly.Įnable the auditd daemon so that it can start at boot time: $ sudo systemctl enable auditd Define audit rules Once auditd is configured, start the service to collect audit information: $ sudo service auditd start The file contains the default configuration parameters that alter the behavior of the auditd daemon. The audit configuration file is located at /etc/audit/nf.
