  from unauthorized access. Network firewalls may
  be hardware devices, software programs, or a
  combination of the two.
• Network firewalls guard an internal computer
  network (home and school) against malicious
  access from the outside. Network firewalls may
  also be configured to limit access to the outside
  from internal users.
• Free Personal Firewalls is a site that recommends
  personal firewall sites.

Proxy Servers

• Proxy servers act as an intermediary between
  internal computers and external networks by
  receiving and selectively blocking data packets
  at the network boundary.
• These network firewalls also provide an extra
  measure of safety by hiding internal Local Area
  Network addresses from the outside Internet.

  unique address that computers use in order to
  identify and communicate with each other on a
  computer network.
• This utilizes the Internet Protocol standard
  which is your computer address.
