      Firewall

      A firewall is designed to prevent unauthorized access to or from a private network. Firewalls can be implemented in both hardware and software, or a combination of both. Firewalls are used to prevent unauthorized Internet users from accessing private networks connected to the Internet, especially intranets. All messages entering or leaving the intranet pass through the firewall, which examines each message and blocks those that do not meet the specified security criteria.
      Your question “what does it need to have a firewall”. What does what need? What are you referring to as “it”? You can install a firewall on anything from a home computer to a WAN!

      The reauirements to have a secure firewall can be thru either, both h/w and s/w, h/w alone, s/w alone. Hardware is the best sullotion in most cases. There is alot of companies out there just for firewalls, Cisco is one of them.
      It works by closing all ports on the firewall for outside traffic and leaving open just the ones you left open, and then also checking it to make sure that its harmless.
