    A firewall is a network security device that monitors and controls incoming/outgoing traffic based on security rules.

    Types of Firewalls:

    • Packet Filtering Firewall – Checks source & destination IP/port.
    • Stateful Inspection Firewall – Tracks active connections.
    • Proxy Firewall – Intermediary between client and server.
    • Next-Generation Firewall (NGFW) – Combines firewall with deep packet inspection, IDS/IPS.
