A firewall is a network security system designed to monitor, filter, and control incoming and outgoing traffic
based on predetermined security rules. It acts as a barrier between trusted internal networks and untrusted
external sources, such as the internet, to prevent malicious activities like hacking, malware attacks,
and data breaches.
Firewalls can be hardware-based, software-based, or a combination of both. Modern firewalls not only block
threats
but also provide detailed traffic analysis, intrusion prevention, VPN services, and more—making them an
essential
part of every organization’s cybersecurity strategy.
