7 Best Firewall FAQs:
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 and a firewall protect devices connected to the Internet or to 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 threats over the Internet or other connected networks.
In cyberspace, data is transferred between your computer and servers and routers. This data, which is transported in packets, is monitored by a firewall to identify and block any unwanted traffic.
The firewall accomplishes this by examining the data packets against the rules that have been defined. If the data packets comply with these rules, the firewalls will accept them. If they don’t follow the rules, the firewall rejects or blocks them.
Today, firewalls help protect computers and other connected devices around the world, whether they are for individual users, large corporations, or the government.
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 harmful data”. However, if we dive into the details, the firewall will use one of three methods or combinations to control the traffic coming in and out of the network.
