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.

Syllabus

Understanding Network Infrastructure and Network Security Monitoring Tools
- This foundational module provides you with a blueprint for modern network security architecture. We will start with essential network functions like Network Address Translation (NAT) and packet filtering with Access Control Lists (ACLs). You will then learn how to manage user and device permissions through Access Control Models and AAA (Authentication, Authorization, and Accounting). Finally, we'll examine the critical security technologies that protect and monitor the network, including load balancers, Web Application Firewalls, network-based malware protection, and various Network Security Monitoring (NSM) tools.
Understanding Common TCP/IP Attacks
- Building on your knowledge of network infrastructure, this module shifts focus to the offensive side of cybersecurity. You will learn to think like an attacker by dissecting the TCP/IP suite to expose common vulnerabilities in protocols like ARP, IP, ICMP, TCP, and UDP. We will analyze how these weaknesses are leveraged to launch real-world attacks, covering techniques for reconnaissance, gaining unauthorized access, and disrupting services through Man-in-the-Middle (MITM), spoofing, and Denial-of-Service (DoS) attacks.
