Why each option
Critical breach prevention features in a Next-Generation Firewall (NGFW) involve comprehensive traffic inspection capabilities and intelligent policy enforcement based on application and content awareness.
While important for alerting, alarm generation itself is a reaction and not a proactive prevention mechanism; prevention aims to stop the threat before it triggers an alarm.
NGFWs leverage Application Visibility (App-ID) to identify and control applications regardless of port, and URL Categorization (URL Filtering) to block access to malicious or inappropriate websites, both crucial for preventing breaches by controlling access and reducing attack surfaces.
This is a function of endpoint protection platforms (EPP) or host-based security systems, not a primary feature of a network firewall that provides breach prevention at the network edge or segment.
A core capability of an NGFW is its ability to inspect all network traffic, irrespective of the port or protocol used, in both ingress and egress directions. This comprehensive inspection ensures that evasive threats cannot bypass security mechanisms by using non-standard ports or encrypted tunnels.
Log collection is essential for forensics, auditing, and security operations, but it is a logging and management function, not a direct breach prevention feature of the firewall itself.
