Which network device enhances security by performing deep packet inspection, allowing it to identify and block application-layer threats that traditional firewalls may miss?
Router
Next-generation firewall
Traditional stateful firewall
Layer 2 switch
A next-generation firewall provides advanced security by inspecting traffic at the application layer through deep packet inspection. This enables it to detect and prevent sophisticated threats like malware and application-layer attacks that traditional stateful firewalls, which primarily analyze traffic at the transport and network layers, may not catch.
