Fix Recommendation

Configure the operating system to generate audit records when successful/unsuccessful attempts to use the "renameat" syscall occur.

Add the following rules in "/etc/audit/rules.d/audit.rules":

-a always,exit -F arch=b32 -S renameat -F auid>=1000 -F auid!=unset -k delete

-a always,exit -F arch=b64 -S renameat -F auid>=1000 -F auid!=unset -k delete

The audit daemon must be restarted for the changes to take effect.

Check Contents

Verify the operating system generates audit records when successful/unsuccessful attempts to use the "renameat" syscall occur.

Check the file system rules in "/etc/audit/audit.rules" with the following commands:

# grep -iw renameat /etc/audit/audit.rules

-a always,exit -F arch=b32 -S renameat -F auid>=1000 -F auid!=unset -k delete

-a always,exit -F arch=b64 -S renameat -F auid>=1000 -F auid!=unset -k delete

If both the "b32" and "b64" audit rules are not defined for the "renameat" syscall, this is a finding.
