Tracking down hacked machines would be quicker.  Sometimes you might
be able to track back to the source where you could pull the ANI

someone knocking on their door.  You only have to do this for 1 in 10
attacks before rumors spread around the hacker community and it stops.

I hate to tell you, but ANI and caller-id can be spoofed too.

However, I agree that encouraging as much source filtering as possible
would be "a good thing."  Just as long as people don't get the idea
that source filtering would make authentication by source IP address
any more secure than authentication by caller-id.

Now, if we could just get the phone company to not charge 1,000% markup
on caller-id, we'd have it on all our modem lines now.

Can anyone remember what the hardest part was about finding Mitnick?
After having a relatively easy time tracing him to Netcom the problem
was figuring out where he was entering the phone system via cell phone
and it was determined that he had broken into the phone system and
probably been frollicing there for about 2 years.
