Palo Alto Networks Certified Cybersecurity Entry-level Technician (PCCET)Network SecurityMedium
A security architect is designing a network for a new branch office that will handle sensitive customer data. The design includes a firewall that can inspect the full context of network traffic, including the application layer, user identity, and content, to make more intelligent security decisions beyond traditional port and protocol filtering. What type of firewall is the architect likely considering for this implementation?
- ANext-Generation Firewall (NGFW)
- BPacket-filtering firewall
- CStateful firewall
- DProxy firewall
Show answer & explanationAnswer & explanation
Correct answer: A. Next-Generation Firewall (NGFW)
Next-Generation Firewalls (NGFWs) offer deeper packet inspection, including application awareness, user identity awareness, and integrated intrusion prevention, going beyond basic port and protocol filtering.
Why the other options are wrong
- B. Packet-filtering firewalls only inspect header information (IP, port, protocol) without context.
- C. Stateful firewalls track connection states but lack application-level awareness and user identity integration.
- D. Proxy firewalls act as an intermediary but typically don't offer the broad, integrated security features of an NGFW across all layers.
Next-Generation Firewall (NGFW)
An advanced firewall that combines traditional firewall capabilities with deep packet inspection, intrusion prevention, application awareness, and identity awareness.
- Inspects traffic beyond port and protocol, up to the application layer.
- Integrates intrusion prevention system (IPS) functionality.
- Provides granular control over applications and user identities.
Memory trick: Next-Gen firewalls are smart, seeing beyond the surface.
