Run the following command to configure the audit log files to be group owned by adm: # find $(dirname $(awk -F"=" '/^\s*log_file/ {print $2}' /etc/audit/auditd.conf | xargs)) -type f \( ! -group adm -a ! -group root \) -exec chgrp adm {} + Run the following command to set the log_group parameter in the audit configuration file to log_group = adm: # sed -ri 's/^\s*#?\s*log_group\s*=\s*\S+(\s*#.*)?.*$/log_group = adm\1/' /etc/audit/auditd.conf Run the following command to restart the audit daemon to reload the configuration file: # systemctl restart auditd
