Understanding Firewall Technologies Firewall technologies play a vital role in network security by monitoring and controlling incoming and outgoing traffic based on predefined security rules. Key types include packet-filtering firewalls, which analyze data packets; stateful inspection firewalls, which track active connections; proxy firewalls, which filter traffic through an intermediary server; and next-generation firewalls (NGFW), which offer advanced features like intrusion prevention and deep packet inspection. These technologies help protect networks from unauthorized access, malware, and other cyber threats.
