What exactly is a firewall?  Well, it is a network security device that monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on a defined set of security rules.

They have been the first line of defence in network security for over 25 years. They establish a barrier between secured and controlled internal networks that can be trusted and untrusted outside networks, such as the Internet. 

A firewall can be hardware, software, or both.  There are five types of firewalls.

  • packet filtering firewall.
  • circuit-level gateway.
  • application-level gateway (aka proxy firewall)
  • stateful inspection firewall.
  • next-generation firewall (NGFW)

Some of the benefits of having a firewall are:

  • Monitors Network Traffic. 
  • Stops Virus Attacks. 
  • Prevents Hacking. 
  • Stops Spyware. 
  • Promotes Privacy.

We hope all of this festive cheer and advice is useful and can be used to ensure you get presents and not coal in the company stocking this year!
