Amazon Linux 2023 must ensure that the rsyslog service is running and persistent.

Configuring Amazon Linux to implement organizationwide security implementation guides and security checklists ensures compliance with federal standards and establishes a common security baseline across the DoW that reflects the most restrictive security posture consistent with operational requirements.

Configuration settings are the set of parameters that can be changed in hardware, software, or firmware components of the system that affect the security posture and/or functionality of the system. Security-related parameters are those parameters impacting the security state of the system, including the parameters required to satisfy other security control requirements. Security-related parameters include, for example: registry settings; account, file, directory permission settings; and settings for functions, ports, protocols, services, and remote connections.

Verify Amazon Linux 2023 is configured so that the rsyslog service is enabled and active with the following commands:

$ sudo systemctl is-enabled rsyslog enabled

$ sudo systemctl is-active rsyslog active

If the service is not "enabled" and "active" this is a finding.

Start the auditd service, and enable the rsyslog service with the following commands:

$ sudo systemctl start rsyslog.service

$ sudo systemctl enable rsyslog.service
