Information

The SUSE operating system must audit all uses of the sudoers file and all files in the /etc/sudoers.d/ directory.

GROUP ID: V-234913
RULE ID: SV-234913r958412

Reconstruction of harmful events or forensic analysis is not possible if audit records do not contain enough information.

At a minimum, the organization must audit the full-text recording of privileged access commands. The organization must maintain audit trails in sufficient detail to reconstruct events to determine the cause and impact of compromise.

Satisfies: SRG-OS-000037-GPOS-00015, SRG-OS-000042-GPOS-00020, SRG-OS-000392-GPOS-00172, SRG-OS-000462-GPOS-00206, SRG-OS-000471-GPOS-00215

Solution

Configure the SUSE operating system to generate audit records when successful/unsuccessful attempts to access the "/etc/sudoers" file and files in the "/etc/sudoers.d/" directory.

Add or update the following rule in "/etc/audit/rules.d/audit.rules":

-w /etc/sudoers -p wa -k privileged-actions

-w /etc/sudoers.d -p wa -k privileged-actions

To reload the rules file, restart the audit daemon

sudo systemctl restart auditd.service

or issue the following command:

sudo augenrules --load
