Check Text ( C-57669r846638_chk )

Verify the audit tools are protected from unauthorized access, deletion, or modification by checking the permissive mode. Check the octal permission of each audit tool by running the following command: $ sudo stat -c "%a %n" /sbin/auditctl /sbin/aureport /sbin/ausearch /sbin/autrace /sbin/auditd /sbin/rsyslogd /sbin/augenrules 750 /sbin/auditctl 750 /sbin/aureport 750 /sbin/ausearch 750 /sbin/autrace 750 /sbin/auditd 755 /sbin/rsyslogd 755 /sbin/augenrules If any of the audit tools has a mode more permissive than "0755", this is a finding.

Fix Text (F-57620r846639_fix)
Configure the audit tools to be protected from unauthorized access by setting the correct permissive mode using the following command: $ sudo chmod 0755 [audit_tool] Replace "[audit_tool]" with the audit tool that does not have the correct permissive mode.
