Which of the following describes a system that enforces a boundary between two or more networks, typically forming a barrier between a secure and an open environment such as the Internet?
A firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It establishes a barrier between a secure internal network and an untrusted external network, such as the internet. This system is designed to prevent unauthorized access to or from private networks and is a fundamental piece of a comprehensive security framework for any organization.
