What is a Firewall?
“Firewall” is one of the first things you hear come out of a techie’s mouth in any hacker movie, but what truly is it? Let’s take a look!
A firewall is a system that prevents unauthorized access from entering a private network. It does this by creating a barrier and blocking unwanted traffic.
Firewalls are used in networks and organizations with one or multiple computers/servers so they remain protected from malicious activity.
