Vulnerability Discussion

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.

AlmaLinux OS 9 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

Verify the audit tools have a mode of "0755" or less with the following command:

$ stat -c "%#a %n" /sbin/auditctl /sbin/aureport /sbin/ausearch /sbin/autrace /sbin/auditd /sbin/rsyslogd /sbin/augenrules

0755 /sbin/auditctl
0755 /sbin/aureport
0755 /sbin/ausearch
0750 /sbin/autrace
0755 /sbin/auditd
0755 /sbin/rsyslogd
0755 /sbin/augenrules

If any of the audit tool files have a mode more permissive than "0755", this is a finding.

Fix

Configure the audit tools to have a mode of "0755" by running the following command:

$ chmod 0755 [audit_tool]

Replace "[audit_tool]" with each audit tool that has a more permissive mode than 0755.
