Network Security Guide
Network security is important if you connect your laptop to network at many different places. Internet brings many threats like viruses, worms or hackers attacks. This could lead to data theft without physical access to your laptop. Prevention methods include firewalls and antivirus software.
Firewalls
Installing firewall should protect you against hackers attacks and worms. It would also greatly improve your privacy while surfing the web as most of them monitor information that your web browser sends to the Internet. But the main role of firewall is to restrict access to your computer from network. For majority of users denying all tries of incoming connections and allowing only outgoing ones is a good choice. Sygate Personal Firewall PRO is one of the best firewalls on the market. It was created by Sygate - one of the most well known security companies. Another very good firewall is BlackICE - by Internet Security Systems (ISS). Looking for good firewall for myself I've tested many different solutions and I've found these two as the best products.
Antivirus Solutions
Everybody has had problems with viruses. Thousands of them are floating around the Internet, coming by email, web sites or infected software. They could lead to data loss or leakage. Some of them are searching for credit card numbers on your hard disk. The only method of protection is installing good antivirus software. You should choose the one, which have its virus database updated very often because new viruses are coming out every day. I find Kaspersky Anti-Virus Personal a very good one.
