Easy to setup, affordable, reliable, this is how firewall, e-mail filtering, messaging and web content filtering has to be.
A good firewall should be inexpensive and easy to use, should hide all ports to protect your PC from attacks and should immediately alert you to serious attacks.
There are complete Internet Security Software Suites to protect also from viruses, worms, spyware, intrusion, phishing and root kits.
Protection can also be done with Hardware Firewalls.
A small hardware device between your modem and your local computer – network.
This hardware firewall uses mostly ‘network address translation’ NAT to hide your PC from the Internet or the more efficient ‘SPI’ for even higher protection.
The three basic types of hardware firewall devices are Wired Routers, Wireless Routers, and Broadband Gateways.
