| Description |
|---|
| If modification of login UIDs is not prevented, they can be changed by nonprivileged users and make auditing complicated or impossible. Satisfies: SRG-OS-000462-GPOS-00206, SRG-OS-000475-GPOS-00220, SRG-OS-000057-GPOS-00027, SRG-OS-000058-GPOS-00028, SRG-OS-000059-GPOS-00029 |
| ℹ️ Check |
|---|
| Verify Amazon Linux 2023 is configured so that the audit system prevents unauthorized changes to login UIDs with the following command: $ sudo grep -i immutable /etc/audit/audit.rules --loginuid-immutable If the "--loginuid-immutable" option is not returned in the "/etc/audit/audit.rules", or the line is commented out, this is a finding. |
| ✔️ Fix |
|---|
| Configure Amazon Linux 2023 auditing to prevent modification of login UIDs once they are set by adding the following line to /etc/audit/rules.d/audit.rules: --loginuid-immutable To load the rules to the kernel immediately, use the following command: $ sudo augenrules --load |
