Firewalls

Firewalls are essential tools in the fight against malicious programs on the

Internet. Firewalls are devices or software that protect an internal network from

unauthorized access to and from the Internet at large. Hardware firewalls protect

networks using a number of methods, such as hiding IP addresses and

blocking TCP/IP ports.Most small office/home office (SOHO) networks use

a hardware firewall, such as the Linksys router. These

devices do a great job.

Windows XP VISTA Windows7 windows 8 comes with an excellent software firewall, called the Windows

Firewall. It can also handle the

heavy lifting of port blocking, security logging, and more.
