Master Network Security with CCNP Security Certification — Hands-On Training & Course Guide
Saturday, October 25, 2025
Introduction If you’re serious about advancing your cybersecurity career, the CCNP Security certification is a powerful step forward. Network Kings’ CCNP Security Training delivers hands-on labs, real-world scenarios and exam-focused guidance to help you pass the CCNP exam and gain the operational skills employers demand. In this blog, we break down what the CCNP Security course covers, why it matters, and how the training prepares you for real-world issues like certificate management, SSL/TLS decryption, captive portals and identity integration.
Watch the lab demo used in this article: (YouTube demo covered DNS, certificate workflows, SSL/TLS decryption, captive portal active authentication, AD integration, OpenSSL CSR creation, RPF troubleshooting and identity visibility.)
Why pursue CCNP Security certification?
Industry recognition: CCNP certification demonstrates advanced skills in designing, implementing and troubleshooting network security technologies.
Career growth: Opens opportunities for senior security engineer, network security architect and SOC roles.
Practical focus: CCNP Security validates hands-on troubleshooting and configuration skills — not just theory.
What you’ll learn in a Network Kings CCNP Security course Our CCNP Security Training emphasizes lab-based learning that mirrors real production tasks. Key topics include:
Platform and network services
Proper DNS and DHCP configuration for management and device operation.
Best practices for production redundancy and management-plane connectivity.
SSL/TLS and certificate lifecycle
Generate private keys and CSRs using OpenSSL.
Submit CSRs to an enterprise CA and import signed certificates.
Import CA root certificates into FMC/FTD trust stores.
Configure SSL/TLS decryption and certificate re-signing for HTTPS inspection.
Deploy certificates for web-based services (captive portal) and for inbound server decryption.
Identity and access control
Active authentication (Captive Portal): create realm, portal certificate and identity rules to authenticate users via AD.
Passive authentication (Cisco ISE + pxGrid): integrate AD, ISE and FMC for seamless user-to-IP mapping.
Configure identity policies and tie them to access control rules to permit/deny traffic based on user identity and AD groups.
Troubleshooting real-world problems
Reverse Path Filtering (RPF) / anti-spoofing issues and how NAT or route design resolves them.
Packet tracer and logs: understanding why some packets never reach the management plane (and where to look).
Host profiling and vulnerability visibility: how FMC displays OS/app fingerprints and CVE-based risk details.
Lab workflows & tools
Using OpenSSL to create keys and CSRs:
openssl genrsa -out ftd_captive.key 2048
openssl req -new -key ftd_captive.key -out ftd_captive.csr
Submitting CSRs to enterprise CA and installing signed cert + private key into the firewall management platform.
How Network Kings CCNP Security Training prepares you for the exam
Exam-relevant labs: We map labs to exam objectives so you learn the exact skills tested by the CCNP Security certification.
Real-world scenarios: Our lessons simulate the daily tasks of network security engineers — certificate management, identity integration, captive portal deployment and troubleshooting.
Instructor-led help and community: Get guided walkthroughs, Q&A, and lab reviews to sharpen your knowledge.
Recommended study roadmap
Foundation: Review CCNP Security exam blueprint and prerequisites (ensure you’re comfortable with CCNA-level networking fundamentals).
Theory + Demos: Learn key concepts (SSL/TLS, identity, NAT, routing, access control).
Lab Practice: Reproduce demo scenarios — DNS changes, CSR generation, CA enrollment, captive portal testing, NAT fixes for RPF.
Mock tests & reviews: Time yourself on practice questions and review lab logs and failures with instructors.
Certification attempt: Schedule the CCNP Security exam and use lab competence to tackle hands-on troubleshooting questions confidently.
