Network Security

Launch your cybersecurity training with a hands-on network security course that teaches how to secure enterprise networks, control access, and defend against real-world attacks. Designed for aspiring associate-level cybersecurity analysts and learners with CCNA-level knowledge, this program builds practical skills in infrastructure security, secure device access, and access control using standard and extended ACLs, including both numbered and named configurations. You’ll also learn control plane security with Control Plane Policing (CoPP) and get introduced to MQC for building CoPP policies on Cisco IOS. The course covers core network security technologies and protocols, including Authentication, Authorization, and Accounting (AAA), RADIUS, TACACS+, firewalls, IPS, and NAT, while explaining how AAA improve scalability, manageability, and control. A key differentiator is its dual perspective: you’ll study both defensive security and attacker techniques by examining TCP/IP vulnerabilities and common threats such as Man-in-the-Middle, spoofing, and Denial-of-Service attacks. By the end, learners will be prepared to monitor, analyze, and help defend networks in a Security Operations Center (SOC) environment.
