Discussion

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 operating system activity. Satisfies: SRG-OS-000057-GPOS-00027, SRG-OS-000058-GPOS-00028, SRG-OS-000059-GPOS-00029

Check Content

Verify the group owner of newly created audit logs is "root" by using the following command:  
 
     $ sudo grep -iw log_group /etc/audit/auditd.conf 
     log_group = root 
 
If "log_group" is not set to "root", this is a finding.

Fix Text

Configure the group owner of newly created audit logs to be "root". 
 
Add or modify the following lines in the "/etc/audit/auditd.conf " file: 
 
log_group = root 
 
Reload the configuration file of the audit service to update the group ownership of existing files: 
 
     $ sudo systemctl kill auditd -s SIGHUP
