Assessment Title

Rule Text

RHEL 10 must enforce group ownership by "root" or a restricted logging group for audit log files to prevent unauthorized access.

Description

Discussion Text

Unauthorized disclosure of audit records can reveal system and configuration data to attackers, thus compromising its confidentiality. Satisfies: SRG-OS-000057-GPOS-00027, SRG-OS-000058-GPOS-00028, SRG-OS-000059-GPOS-00029, SRG-OS-000206-GPOS-00084

Remediation

Configure RHEL 10 to enforce group ownership by "root" or a restricted logging group for audit log files to prevent unauthorized access.

Identify the group that is configured to own the audit log:

$ sudo grep -P '^[ ]*log_group[ ]+=.*$' /etc/audit/auditd.conf

Change the ownership to that group using the following command:

$ sudo chgrp ${log_group} ${log_file}
