Firewall
A firewall is a network security device that monitors and filters incoming and outgoing network traffic based on predefined security rules, acting as a barrier between a trusted internal network and untrusted external networks like the internet. Its main purpose is to prevent unauthorized access and protect against cyber threats.
TECHNICAL DEFINITION
A firewall is a network security system, implemented in hardware or software, that enforces an organization's security policy by inspecting and controlling network traffic (e.g., packets) between different security zones, primarily to block unauthorized access and mitigate cyber threats.
BACKGROUND
Computer security is a subdiscipline within the field of information security. It focuses on protecting computer software, systems, and networks from threats that can lead to unauthorized information disclosure, theft, or damage to hardware, software, or data, as well as to the disruption or misdirection of the services they provide.
