Firewalls

A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules, acting as a barrier between a trusted network and an untrusted network. By blocking unauthorized access and malicious activity, firewalls play a crucial role in protecting computer systems and networks from cyber threats, making them a fundamental component of modern cybersecurity infrastructure and a key topic of discussion among tech professionals and organizations seeking to safeguard their digital assets.
