Security Threats Won't Let Up This Year: Page 6 of 6

Businesses battling continuing waves of security threats may need to add new weapons to their arsenals. In addition to quick patching, effective firewall policies, strict remote-user security rules, and keeping antivirus software up to date, businesses should look at intrusion-prevention applications such as those offered by Cisco Systems, Internet Security Systems, Network Associates, Platform Logic, and Sana Security. These applications don't rely on threat signatures and software policies to thwart attacks. Instead, they attempt to block new attacks long before antivirus, intrusion-detection, and firewall systems and policies can be updated.

Want a safe prediction for the new year? Here's one: Companies will face new threats that no one expects, plus many variations of the old threats. Information-security pros aren't willing to predict much progress in the battle against worms, viruses, and other security threats. But there's one thing nearly all of them do agree on: Businesses must continue to devote time, money, and personnel to keep their systems as safe as possible.
