What is a Firewall?
Answer
A Firewall is a critical network security system that strictly monitors and aggressively filters incoming and outgoing network traffic based on mathematical rules.
A Firewall is a physical hardware appliance or highly specialized software architecture that establishes an absolute barrier between a trusted internal corporate network and an untrusted external network (like the Internet). It aggressively monitors all incoming and outgoing data packets, utilizing rigorous mathematical rule-sets to either permit or violently block the traffic.
