  • A firewall is a software program or a piece of hardware that filters out hackers, worms, virus, etc. that try to reach your computer over the internet. Stateful inspection firewall makes the filtering decisions to determine whether data is allowed to pass through to the user. These rules are often based on the decisions set up by the administrator when setting up the computer and firewall.

Firewalls prevent unauthorized internet users from accessing private networks connected to the internet, especially intranets. All messages entering or leaving the intranet (i.e., the local network to which you are connected) must pass through the firewall, which examines each message and blocks those that do not meet the specified security criteria.
