Title

The Ubuntu operating system must be configured to preserve log records from failure events. (Cat II impact)

Discussion

Failure to a known state can address safety or security in accordance with the mission/business needs of the organization. Failure to a known secure state helps prevent a loss of confidentiality, integrity, or availability in the event of a failure of the information system or a component of the system. Preserving operating system state information helps to facilitate operating system restart and return to the operational mode of the organization with least disruption to mission/business processes.

Check Content

Verify the log service is configured to collect system failure events. Check that the log service is installed properly with the following command: # dpkg -l | grep rsyslog ii rsyslog 8.32.0-1ubuntu4 amd64 reliable system and kernel logging daemon If the "rsyslog" package is not installed, this is a finding. Check that the log service is enabled with the following command: # sudo systemctl is-enabled rsyslog enabled If the command above returns "disabled", this is a finding. Check that the log service is properly running and active on the system with the following command: # systemctl is-active rsyslog active If the command above returns "inactive", this is a finding.

Fix Text

Configure the log service to collect failure events. Install the log service (if the log service is not already installed) with the following command: # sudo apt-get install rsyslog Enable the log service with the following command: # sudo systemctl enable rsyslog Restart the log service with the following command: # sudo systemctl restart rsyslog
