Personal Firewall Pro 5.0, is targeted at home and small office/home office users and performs standard firewall tasks such as blocking unwanted connections to a computer and detecting possible attacks. The new version adds new security features to protect operating systems, networks and applications, according to Babak Salimi, product manager at Sygate.
The new version of the firewall protects users from Denial of Service clients and trojans, Salimi said. It also adds features to block spoofing, a technique used in computer attacks by which the attacking computer is made to appear to have an IP address other than its own and blocks attacks using such recent vulnerabilities as the flaw in Windows XP's Universal Plug and Play service, he said.
Also fixed in the new version is a flaw found in a number of personal firewalls that allows programs that use code other than the one supplied by Microsoft in Windows to generate outbound connections, he said. Firewalls generally block outbound connection attempts, which are often the hallmark of a trojan or Denial of Service attack.
Sygate Personal Firewall Pro is immediately available worldwide at a cost of $39.95 (£27.86) per user.
