Description
Unauthorized disclosure of audit records can reveal system and configuration data to attackers, thus compromising its confidentiality. Audit information includes all information (e.g., audit records, audit settings, audit reports) needed to successfully audit OL 8 system activity. Satisfies: SRG-OS-000057-GPOS-00027, SRG-OS-000058-GPOS-00028, SRG-OS-000059-GPOS-00029

Check Text ( C-52171r779775_chk )
Verify the audit log directories have a mode of "0700" or less permissive by first determining where the audit logs are stored with the following command: $ sudo grep -iw log_file /etc/audit/auditd.conf log_file = /var/log/audit/audit.log Using the location of the audit log, determine the directory where the audit logs are stored (ex: "/var/log/audit"). Run the following command to determine the permissions for the audit log folder: $ sudo stat -c "%a %n" /var/log/audit 700 /var/log/audit If the audit log directory has a mode more permissive than "0700", this is a finding.

Verify the audit log directories have a mode of "0700" or less permissive by first determining where the audit logs are stored with the following command:

$ sudo grep -iw log_file /etc/audit/auditd.conf

log_file = /var/log/audit/audit.log

Using the location of the audit log, determine the directory where the audit logs are stored (ex: "/var/log/audit"). Run the following command to determine the permissions for the audit log folder:

$ sudo stat -c "%a %n" /var/log/audit

700 /var/log/audit

If the audit log directory has a mode more permissive than "0700", this is a finding.

Fix Text (F-52125r779776_fix)
Configure the audit log directory to be protected from unauthorized read access by setting the correct permissive mode with the following command: $ sudo chmod 0700 [audit_log_directory] Replace "[audit_log_directory]" to the correct audit log directory path. By default, this location is "/var/log/audit".
