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. RHEL 8 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, 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.

Check Text ( C-33141r568162_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 755 /sbin/auditctl 755 /sbin/aureport 755 /sbin/ausearch 750 /sbin/autrace 755 /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.

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

755 /sbin/auditctl
755 /sbin/aureport
755 /sbin/ausearch
750 /sbin/autrace
755 /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-33116r568163_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.
