Firewall Defender

A firewall is a network security device that monitors and filters incoming and outgoing network traffic based on an organization's previously established security policies. It acts as a barrier between trusted internal networks and untrusted external networks, such as the Internet.

Key firewall features in this game:

• Port Blocking: Prevents access to specific network ports
• Protocol Filtering: Blocks or allows traffic based on protocols (e.g., TCP, UDP, SMTP)
• Packet Inspection: Examines the contents of data packets for potential threats

By configuring these settings correctly, you can protect your network from various cyber threats.
