* '''Network Security''' — The policies and practices adopted to prevent and monitor unauthorized access, misuse, or denial of a computer network.
* '''Firewall''' — A security device that monitors and filters incoming and outgoing network traffic based on an organization's previously established security policies.
* '''VPN (Virtual Private Network)''' — A tool that creates an encrypted "Tunnel" over the public internet to protect your data and identity.
* '''IP Address''' — A unique string of numbers that identifies each computer using the Internet Protocol to communicate over a network.
* '''Port''' — A "Virtual Doorway" on a computer used for specific types of traffic (e.g., Port 80 for web, Port 22 for secure login).
* '''Intrusion Detection System (IDS)''' — A device or software application that monitors a network for malicious activity or policy violations.
* '''DDoS (Distributed Denial of Service)''' — An attack where multiple compromised systems flood a target network with traffic to crash it.
* '''Phishing''' — A fraudulent attempt to obtain sensitive information by disguising as a trustworthy entity in electronic communication.
* '''Man-in-the-Middle (MitM)''' — An attack where the attacker secretly relays and possibly alters the communications between two parties who believe they are directly communicating.
* '''Encryption (In Transit)''' — Protecting data while it is moving across the network (e.g., HTTPS).
* '''Zero Trust''' — A security model that requires all users, whether in or out of the network, to be authenticated and validated before being granted access.
* '''DMZ (Demilitarized Zone)''' — A physical or logical subnetwork that contains an organization's external-facing services (like a website) to keep the internal network safe.
* '''Encryption (At Rest)''' — Protecting data while it is stored on a disk or database.
* '''MAC Address''' — A unique identifier assigned to a network interface controller (NIC) for communications at the data link layer.
