Firewalls are Today's Necessity

A study from the University of Maryland reported that computers connected to the internet were attacked about every 39 seconds resulting in 2,244 attacks per day. The anti-virus company, Sophos, reports that many of the malware coming into computer systems are now trojans versus viruses which represent a 4-to-1 ratio respectively. Firewalls are now becoming a necessary front in warding off difficult to stop malware.

The first line of defense is protecting the perimeter with a hardware firewall.
