sudo does do logging, but unless you have remote logging, a clever
intruder can delete the log entries and thereby cover their tracks.
Functionally, as far as privileges are concerned sudo is similar to su.
However, you can configure sudo to limit the commands (and even
argument) an authorized user is allowed to run.  So it can be a big
security improvement over just granting blanket root access.
