Firewalls: Essential Legal Insights and Definitions for Cybersecurity
Definition & meaning
A firewall is a security system that protects a computer network by monitoring and controlling incoming and outgoing traffic. It acts as a barrier between a trusted internal network and untrusted external networks, such as the Internet. Firewalls can be implemented as hardware devices, software applications, or a combination of both. Their primary purpose is to prevent unauthorized access and ensure that only legitimate traffic is allowed through.
