Information
The auditd service is the userspace daemon of the Linux Auditing System. When enabled and active it records system events to the audit log.
The capturing of system events provides system administrators with information to allow them to determine if unauthorized access to their system is occurring.
Solution
Run the following commands to unmask, enable, and start auditd :
# systemctl unmask auditd
# systemctl enable auditd
# systemctl start auditd
Impact:
Running auditd records system events, which consumes some CPU and disk space for the audit logs.
