TACACS encryption won't help if you follow the Cisco Essential IOS Features

Unfortunately, this will log in your syslog the password commands in
cleartext.  You would have to be sure that the Unix/NT system you are
logging all Cisco commands to is as secure as your router.  How many of you
run ISS/Cybercop/Netrecon scans every week on your logging servers to be
sure they are secure?

Hrm, that's odd, since I was using TACACS+ accounting a while ago (that
exact command actually) and it never logged any passwords that I entered...
