Fix Recommendation

Configure RHEL 10 to generate audit records upon successful and unsuccessful uses of the "umount2" system call by adding or updating the following rules in a file in "/etc/audit/rules.d":

-a always,exit -F arch=b32 -S umount2 -F auid>=1000 -F auid!=unset -k privileged-umount
-a always,exit -F arch=b64 -S umount2 -F auid>=1000 -F auid!=unset -k privileged-umount

Restart the audit daemon with the following command for the changes to take effect:

$ sudo service auditd restart

Check Contents

Verify RHEL 10 generates an audit record for all uses of the "umount2" system call with the following command:

$ sudo auditctl -l | grep umount2
-a always,exit -F arch=b64 -S umount2 -F auid>=1000 -F auid!=-1 -F key=privileged-umount
-a always,exit -F arch=b32 -S umount2 -F auid>=1000 -F auid!=-1 -F key=privileged-umount
