Palo Alto Networks Certified Network Security Administrator (PCNSA)

Misconfigured next-generation firewalls create real risk: rules that permit too much traffic, NAT and routing errors that cause outages, and admins overwriting each other's changes. IT Directors assign this PCNSA course to standardize how their security team installs, manages, and tunes Palo Alto Networks firewalls.

Role fit: Built for IT Practitioners and security admins with roughly three to five years of experience with security appliances. Deep security expertise isn't required. It suits teams that run Palo Alto firewalls today or are rolling them out, and Team Leads who need consistent skills across shared admin duties.

Time investment: About 18.4 hours across 18 skills. Training Managers can schedule one skill per week, or assign the full sequence for PCNSA certification readiness.

Risk and change-management notes: The course covers management access options, API-based management, multi-admin access with config and commit locks, and reverting configurations. It also covers how to review firewall data in the Application Command Center and use temporary rules and policy optimization to tighten access without breaking traffic. Panorama lessons show centralized management for Palo Alto firewalls, including policy and object management with device groups.

Hands-on practice: Instructor Keith Barker opens by walking learners through building a Palo Alto firewall lab in ESXi. Your team can then practice routing, NAT, decryption, and policy changes outside production before applying them to live firewalls.

IT teams complete this training to run Palo Alto next-generation firewalls with fewer deployment surprises and tighter, more auditable policy. Instructor Keith Barker builds a working lab and walks through concepts, configuration, and verification for each skill, so Team Leads can see the work done end to end before it touches production.

• Faster first-deployment troubleshooting: Your team learns to check the three usual suspects when traffic stops on a new firewall: interface setup, security policy permissions, and routing. That shortens time to resolution and cuts escalations.
• Safer change control with multiple admins: Practitioners configure separate administrator accounts, use config and commit locks so admins don't overwrite each other's candidate changes, and revert a configuration when needed.
• Policies built on applications and identity, not just ports: Your team migrates traditional port-based rules to App-ID and User-ID, maps Active Directory groups through LDAP, and tests policy matches at the firewall before changes create unintended results. The training also introduces Policy Optimizer as a tool for improving security policy rules.
• Threat prevention and consistent management at scale: Learners work with antivirus, WildFire, anti-spyware, and URL filtering profiles, including verification steps such as confirming SSL decryption behavior for different traffic types. They also handle PAN-OS and content updates without common gotchas and onboard firewalls into Panorama for centralized management across sites and data centers.

The result for IT Directors is standardized Palo Alto administration skills across the team and a clear path toward PCNSA certification readiness.

Knowledge

• How Palo Alto firewall management works across the web interface, CLI, and XML API, including candidate vs. committed configurations
• Why new deployments usually fail on three things: interfaces/zones, missing security policy, and routing — and how to check each one first
• How security policy rules use zones, address objects, App-IDs, application-default ports, and User-ID groups learned through LDAP from Active Directory
• How source NAT, destination NAT, and port redirection work, and when to use Layer 3, Layer 2, VLAN, TAP, or virtual wire interfaces
• How threat prevention, URL filtering, updates, and SSL/TLS decryption help add protection and visibility to allowed traffic
• How Panorama onboards and centrally manages firewalls across data centers, buildings, and firewall roles

Ability

• Build a hands-on Palo Alto firewall lab in ESXi and configure management access, IPv4 routing, and NAT
• Set up multiple administrators with authentication sequences and configuration locks so changes don't collide, and revert configurations when needed
• Write and verify App-ID and User-ID based security policy rules, then confirm results in traffic logs
• Apply threat-prevention controls and SSL/TLS decryption policies, and validate them with lab traffic
• Plan and apply PAN-OS, antivirus, threat, and App-ID updates while avoiding common gotchas
• Optimize legacy port-based rules with temporary monitoring rules, logs, and the Application Command Center
