NGFW Engineer study guide
NGFW Engineer · Work through your exam, one topic at a time.
The NGFW Engineer certification is aimed at network security engineers who install, configure and operate a next-generation firewall estate rather than simply administering a single appliance. Typical candidates work with branch and data-centre firewall deployments, central management servers, routing integration, site-to-site and remote-access VPNs, and clustered high-availability pairs. The NGFW Engineer study guide has 6 sections and about 1,491 words.
01Deployment and Installation
NGFW deployment begins with choosing the interface model: routed (L3) interfaces bound to zones, transparent/virtual-wire, or TAP for monitoring only. A common trap is assuming virtual-wire provides routing or NAT-it forwards at Layer 2 and still requires policy.
268 words, about 1 min02Policy Configuration and Management
Security policy is evaluated top-down, first match wins, with an implicit deny at the bottom. Understand zones (intra-zone versus inter-zone defaults), source/destination/user/application/service fields, and the difference between port-based service and application identification.
273 words, about 1 min03Routing and Networking
NGFWs route between zones using a virtual router or routing instance. Route selection uses longest prefix match first, then administrative distance, then metric.
249 words, about 1 min04VPN Configuration
IPsec has IKE phase 1 (ISAKMP SA) and phase 2 (IPsec SA). Match proposals: encryption (AES-GCM or CBC), integrity, DH group, and lifetime; IKEv2 is preferred, while IKEv1 requires awareness of main versus aggressive mode.
243 words, about 1 min05High Availability and Clustering
HA pairs use a control link (HA1) for hellos and configuration sync, a data link (HA2) for session sync, and optionally HA3 for backups. Active/passive is simplest; active/active requires careful routing and can create asymmetric flows.
222 words, about 1 min06Monitoring, Logging and Reporting
NGFWs generate traffic, threat, system, configuration, and audit logs. Forward via syslog (UDP/TCP/TLS), SNMP traps for events, SNMP polling for counters, and NetFlow/IPFIX for flow analytics.
