We're fortunate that our systems in NCCE are administered quite well. We try to be good netizens to insure that our systems aren't used by e-thugs in malicious ways. In spite of all our precautions we still get hacked. You would be amazed at the amount of staff time used to repair hacker damage. In most cases you, as users of the systems, have no idea that your systems have even been compromised.
