Description
Protecting audit information also includes identifying and protecting the tools used to view and manipulate log data. Therefore, protecting audit tools is necessary to prevent unauthorized operation on audit information. Operating systems providing tools to interface with audit information will leverage user permissions and roles identifying the user accessing the tools and the corresponding rights the user enjoys in order to make access decisions regarding the access to audit tools. Audit tools include, but are not limited to, vendor-provided and open source audit tools needed to successfully view and manipulate audit information system activity and records. Audit tools include custom queries and report generators. Satisfies: SRG-OS-000256-GPOS-00097, SRG-OS-000257-GPOS-00098

Check Text ( C-64221r953287_chk )
Verify Ubuntu 22.04 LTS configures the audit tools to have a file permission of "755" or less to prevent unauthorized access by using the following command: $ stat -c "%n %a" /sbin/auditctl /sbin/aureport /sbin/ausearch /sbin/autrace /sbin/auditd /sbin/audispd* /sbin/augenrules /sbin/auditctl 755 /sbin/aureport 755 /sbin/ausearch 755 /sbin/autrace 755 /sbin/auditd 755 /sbin/audispd-zos-remote 755 /sbin/augenrules 755 If any of the audit tools have a mode more permissive than "0755", this is a finding.
