Common features of firewalls

Firewalls are an essential component of network security that serve as a barrier between a trusted internal network and untrusted external networks, such as the internet. Common features of firewalls include packet filtering, which examines packets of data as they pass through the firewall to determine if they should be allowed or blocked based on predetermined rules; stateful inspection, which keeps track of the state of active connections to ensure only legitimate traffic is allowed through; proxy services, which act as intermediaries for connections between internal and external networks to enhance security; and application layer filtering, which examines the content of data packets to prevent unauthorized access to specific applications or protocols. These features work together to provide comprehensive protection against various cyber threats and unauthorized access attempts.
