Wow, Symantec is making an amazing claim.  They were able to detect
the slammer worm "hours" before.  Did anyone receive early alerts from
Symantec about the SQL slammer worm hours earlier?  Academics have
estimated the worm spread world-wide, and reached its maximum scanning
rate in less than 10 minutes.

I assume Symantec has some data to back up their claim.

  "For example, the DeepSight Threat Management System discovered the
  Slammer worm hours before it began rapidly propagating. Symantec's
  DeepSight Threat Management System then delivered timely alerts and
  procedures, enabling administrators to protect against the attack
  before their environment was compromised."



One way they could have known about it is that some of their
customers got nailed _and called them_.

The other is IDS signature. I'm not sure if there was one already
out there that would have caught this, but if the customers were
calling they would have been able to create one quickly, as
people did.

If there's no alarm, no event tripped, there is no correlation
data.

YMMV.
