Instead of renaming it, you may want to disable interactive logins for the
SYSTEM account altogether, or you may want to investigate about tightening
timeouts for the intrusion detection function (see SHOW INTRU command), so
that VMS will not allow logins from accounts for which a certain threshold
has been reached, even if the attacker guesses the password. :)
Totally agree on disabling interactive logins. But I would perhaps limit that to just
network logins. (I believe VMS can also make that distinction.)
However, if the intrusion system disables the account, it becomes a rather ugly DOS
vector. Not sure how they were thinking there?
Here?s the weird thing about VMS (well I guess it?s the TCP/IP Layered Product generating
the events so maybe the weird thing about both MULTINET and HP?s TCP/IP LP):
- DECNET logins are shown as REMOTE/NETWORK
- TCP/IP logins are shown as _LOCAL_.
I always wondered where the logic behind that was.
Is there any way to limit logins to say JUST NETWORK because that would effectively
disable TCP/IP logins, no?
