A firewall is a network security system that controls incoming and outgoing traffic based on predefined rules. Its purpose is to protect against unauthorized access, malware, and other security risks.
A firewall can be hardware-based, software-based, or a combination of both. Firewalls are important in very large environments, but they are just as useful in smaller networks—even a single PC can benefit from one. It creates a barrier between your internal network and the Internet.
Of course, cybersecurity involves much more than just a firewall. Effective cybersecurity starts with a solid cybersecurity strategy!
