What is a Firewall?
A firewall is a sort of network security hardware or software application that monitors and filters incoming and outgoing network traffic according to a set of security rules. It functions as a firewall between internal private networks and public networks (such as the public Internet).
A firewall's main goal is to allow non-threatening communication while blocking dangerous or undesirable data transmission in order to protect the computer from viruses and attacks. A firewall is a cybersecurity solution that filters network traffic and helps users in preventing harmful malware from gaining access to the Internet on compromised machines.
