A firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between a trusted internal network and untrusted external networks, such as the internet.

Key Features of Firewalls:

🔰 Traffic Filtering

  • Firewalls inspect all incoming and outgoing data packets, allowing or blocking them based on security rules.

🔰 Access Control

  • They enforce policies on which applications or services are accessible, helping to prevent unauthorized access.

🔰 Logging and Monitoring

  • Firewalls log traffic activity, providing valuable data for security analysis and auditing.

🔰 Intrusion Prevention

  • Some advanced firewalls can detect and block suspicious activities, acting as an additional layer of defense against cyber attacks.

Types of Firewalls:

Packet-Filtering Firewalls

Examine packets and block or allow them based on the source/destination IP addresses, ports, or protocols.

Stateful Inspection Firewalls

Monitor the state of active connections and make decisions based on the context of the traffic.

Proxy Firewalls

Operate at the application layer, acting as an intermediary between end users and the resources they are accessing.

Next-Generation Firewalls (NGFW)

Provide deeper inspection capabilities, including intrusion detection, application awareness, and user identity management.
