This check and some related ones require auditing for all users and
The suggested line includes these elements:
-a always,exit -F arch=ARCH -S rmdir,unlink,unlinkat,rename,renameat -F
auid>=500 -F auid!=4294967295 -k delete
Should this check include "-F auid=0" to properly audit the root user?
IIRC the motivation why "-F auid=0" was omitted at the time when writing
these audit rules for SSG it is / was
as follows -- you don't need to audit actions of root user (they need to be
trusted). IOW there is just one user,
able to act as root, and that one should / needs to be trusted.
If root user account is shared between multiple users (and therefore you
truly need to audit root account), you would have more troubles at the
system (because would actually deny the traceability / mapping of performed
actions back to the user, who performed these actions). In such case even
having audit log entry, you couldn't tell which of the users sharing the
root account performed the particular action.
That's why "-F auid=0" argument doesn't need to be present in those
If you need them, there's something
wrong with the design how your system allows to use the 'root' user account.
