πŸ“š Quick Study Guide

  • πŸ›‘οΈ A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules.
  • 🚦 Firewalls act as a barrier between a trusted internal network and an untrusted external network, such as the Internet.
  • 🧱 Firewalls can be hardware, software, or a combination of both.
  • πŸ“ Packet filtering firewalls examine each packet and allow or deny based on source/destination IP address, port number, and protocol.
  • πŸ”‘ Stateful inspection firewalls track the state of network connections and make decisions based on the context of the connection.
  • 🌐 Proxy firewalls act as an intermediary between systems, hiding the true IP address of the protected system.
  • πŸ’‘ Next-generation firewalls (NGFWs) include advanced features like intrusion prevention, application control, and malware filtering.
