The most frequently asked questions about firewalls are listed below.
Q # 1) What is a firewall?
Answer: A shield or barrier protecting 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-based malware on the Internet or other connected networks.
In cyberspace, data is transferred between your computer and servers and routers. Transmitted in packets, this data is monitored by the firewall to identify and block unwanted traffic.
The firewall does this by checking that the data packets comply with the established rules. If data packets match these rules, firewalls will accept them. If they don’t follow the rules, the firewall will deny or block them.
Firewalls today help protect computers and other connected devices around the world, whether for individuals, large corporations or governments.
Q # 2) How does the firewall work?
Answer: Simply put, firewalls work by monitoring traffic to accept or allow “good data” while denying 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 inside and outside the network.
