cyberstrikeus 1.5.1.5 Ensure permissions on /etc/issue are configured (Automated)
Description
The contents of the /etc/issue file are displayed to users prior to login for local terminals.
Rationale
If the /etc/issue file does not have the correct ownership it could be modified by unauthorized users with incorrect or misleading information.
Audit Procedure
Run the following command and verify Uid and Gid are both 0/root and Access is 644:
# stat /etc/issue
Access: (0644/-rw-r--r--) Uid: ( 0/ root) Gid: ( 0/ root)
Expected Result
The output should show Access: (0644/-rw-r--r--), Uid: ( 0/ root), and Gid: ( 0/ root).
Remediation
Run the following commands to set permissions on /etc/issue:
# chown root:root /etc/issue
# chmod 644 /etc/issue
/etc is stateless on Container-Optimized OS. Therefore, the steps mentioned above needs to be performed after every boot.
