Less than 2% of computer attacks on military are successful

[Sean Donelan]

After last weeks spam run on Iraq, the US military and NIPC are
concerned Iraq might be behind a rise in electronic attacks
against government and military networks.

The assessment said recent computer disruptions have included Web
defacements, "denial of service" attacks that can disrupt or paralyze
a network, and hacking "probes" and "scans" aimed at testing the
vulnerability of a network.

But the article also says less than 2% of the "attacks" resulted
in a successful intrusion.
