CCNA Security
CCNA Security
Overview
This comprehensive CCNA Security course builds strong foundational and practical skills in network security using Cisco technologies.
Starting from core security concepts, threats, and risk management, it progresses to real-world Cisco router/switch hardening, AAA authentication, Layer 2 protections, ACLs, Zone-Based Firewall, and IPSec VPN configuration — all aligned with Cisco security best practices.
Ideal for beginners, network engineers, or IT professionals who want to secure Cisco networks, understand hacker techniques, implement defenses, and prepare for roles in network security or certifications like CCNA Security (or foundational prep for CCNP Security).
