It's a good tool, but use it with due caution.  We uncovered a bug in the
VMS operating system IP stack by crashing it with a safe (i.e. no DOS
vulnerability checks enabled) ISS scan.  My policy is to verify scanner
updates on test systems before targeting production systems with it.  And
when scanning the production environment, we don't scan redundant systems
simultaneously.  If you happen to crash the A system, for example, you want
a viable B system to failover to.  If you had both included in the same
scan, you take the risk of taking them both down.  =(

Subject: [ISSForum] Internet scanner - intrusive?


Are internet scanner scans intrusive in nature, for example, can a
scan crash or otherwise damage a server?

TIA,
