Definition of «firewall»

A firewall is a security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules, acting as a barrier between an internal network and external sources to block unauthorized access while permitting authorized communications.

Usage examples

  1. Configuring a firewall: This involves setting up rules and filters to control network traffic, such as blocking certain ports or IP addresses.
  2. Firewall logs: Monitoring and analyzing firewall logs can help identify potential security threats or suspicious activities.
  3. Intrusion detection and prevention systems (IDPS): Firewalls often work in conjunction with IDPS to detect and prevent unauthorized access or malicious activities on a network.
