5.1.1.4 Ensure journald is configured to write logfiles to persistent disk (Automated)
Profile
- Level: 1 - Server
- Level: 1 - Workstation
- Assessment Status: Automated
Description
Data from journald may be stored in volatile memory or persisted locally on the server. Logs in memory will be lost upon a system reboot. By persisting logs to local disk on the server they are protected from loss due to a reboot.
Rationale
Writing log data to disk will provide the ability to forensically reconstruct events which may have impacted the operations or security of a system even after a system crash or reboot.
Audit Procedure
Command Line
Run the following command to verify that logs are persisted to disk:
grep -Psi '^\h*Storage\h*=\h*persistent\b' /etc/systemd/journald.conf /etc/systemd/journald.conf.d/*
Verify the output matches:
Storage=persistent
Expected Result
The output should include Storage=persistent.
Remediation
Command Line
Edit the /etc/systemd/journald.conf file or a file ending in .conf in /etc/systemd/journald.conf.d/ and add the following line:
Storage=persistent
Restart the service:
systemctl restart systemd-journald
Default Value
Storage=auto
