Firewall FAQ:

The most frequently asked questions about firewalls are listed below.

Q # 1) What is a firewall?

Answer: A shield or barrier that protects a private network from unauthorized access, while a firewall protects devices connected to the Internet or another network, such as a local area network (LAN).

The purpose of installing a firewall on a computer, phone, or tablet is to protect users from data-driven malware on the Internet or other connected networks.

In cyberspace, data is transferred between your computer and servers, and routers. This data, which is transmitted in packets, are monitored by the firewall to identify and block any unwanted traffic.

The firewall does this by checking the data packets for compliance with the established rules. If data packets match these rules, firewalls will accept them. If they do not match the rules, the firewall rejects or blocks them.

Firewalls today help protect computers and other connected devices around the world, whether they are for individuals, large companies, or governments.

Q # 2) How does a firewall work?

Answer: Simply put, firewalls work by monitoring traffic to accept or allow “good data” while rejecting or blocking “bad or malicious data”. However, if we go deeper into the details, the firewall will use one of three methods or combinations to control traffic in and out of the network.
