According to the Gemalto report, 3.3 billion records were hacked in the first half of 2018 (excluding the Government of India’s Aadhar ID breach). By 2013, 4,226 records were lost or stolen every minute.
Windows has seen a fair share of data breaches over the past few decades. It is the most widely used operating system in the world. About 87% of desktops/laptops worldwide use the Windows operating system. Because of its popularity, most viruses and malicious codes are written for Windows.
Microsoft was initially not interested in security threats. They eventually introduced a strong firewall and made additional changes to the security features of Windows XP Service Pack 2, which was released in 2008.
What is a firewall?
A firewall is a program used to improve the security of your computer. This tool prevents access to your computer from an unauthorized source. It also filters network traffic and protects your computer from DoS (Denial of Service Attack) and DDoS (Distributed DoS) attacks.
A firewall is just a “code wall” that checks incoming and outgoing data packets. Please note that a firewall cannot be used as a substitute for an antivirus program.

Q # 1) What is a firewall?
The purpose of installing a firewall on a computer, phone, or tablet is to protect users from data-driven malware threats on the Internet or other connected networks.
The firewall achieves this by examining the data packets based on the defined rules. If the data packets comply with these rules, the firewalls accept them. If they don’t comply with the rules, the firewall rejects or blocks them.
Today, firewalls help protect computers and other connected devices around the world, whether they belong to individual users, large corporations, or the government.
Q # 2) How does a firewall work?
Answer: Put simply, firewalls monitor traffic to accept or allow “good data” while rejecting or blocking “bad or harmful data”. However, if we go into detail, the firewall uses one of three methods, or combinations thereof, to control traffic that is entering and exiting the network.
