Personal firewalls recommended for consumers

Internet users should not only have proper internet security software, but also a fully functional personal firewall to back up the shield put up by the software, an expert has stated.

Professor Norbert Pohlmann, the director of the Gelsenkirchen-based Institute for Internet Security, has highlighted the importance of personal firewalls, saying they are vital for security, reports Newsfactor.com.

Windows XP and Vista already have integrated personal firewalls but the online security expert has said users could customise them to reflect their own needs.

"A personal firewall is used to seal off unnecessary communication channels and reduce the access to only absolutely necessary applications such as sending and receiving e-mail messages and surfing on the internet," he explained.

"An unsecured PC is like a pile of money on a table in the middle of an open meadow. A personal firewall is like a house built around the table."

Firewalls and other security programmes such as anti-virus software, anti spyware and pop up blockers are recommended for internet users.
