Question

Quizplus · Accepted Answer

Stateful packet inspection is currently the dominant firewall filtering method used on main border firewalls today because it tracks the state of network connections and only allows packets that are part of an established connection or have been specifically allowed by predefined rules. This increases security by preventing unauthorized access and reducing the risk of attacks. ACL filtering is more commonly used for internal security and NGFW is a newer technology that combines traditional firewall functionality with additional features like IPS and application control. Application content filtering is a useful technique for filtering specific types of traffic, but it is not the dominant method used for border firewalls.
