A firewall is a network security system (either software or hardware) that reviews, monitors, authorizes and controls the incoming and outgoing network traffic. Depending on the predetermined security rules, settings and protocols, such a firewall will block information coming from the Internet or a network, or allow the details to pass through to your computer.
Being connected to the Internet is often essential in business, but also comes with risks. Firewalls play an important role in screening for hackers, viruses and worms that may try to access your computer over the Internet.
Advantages of Firewalls
Peace of mind.
Added network security.
Blocking of malicious Trojan viruses or malware.
Protection against hackers.
Enforcing a company’s online policies.
