Firewall

A software program or hardware device designed to prevent unauthorized access to computers or networks

How it works?

  • Sits as a gateway between two networks
  • They started as simple routers but became firewall due to how they could segment a network into different physical sub networks
  • It may allow all traffic through unless it meets certain criteria
  • It may deny all traffic through unless it meets a certain criteria

Who needs a Firewall?

  • Anyone with a private network that is connected to a public network
  • Anyone with a single computer connected to the internet
