The Certified Network Defender (CND) certification (312-38) is designed for IT professionals, network engineers, SOC analysts, and security administrators seeking practical skills to secure, monitor, and defend enterprise network infrastructures. This course equips you with the knowledge and techniques needed to detect, prevent, and respond to modern network security threats.
The course provides a comprehensive approach to network defense, covering network security fundamentals, incident detection, secure configurations, threat mitigation, and compliance. You’ll gain expertise in protecting networked systems, managing security policies, and analyzing vulnerabilities across on-premises and cloud-based infrastructures.
Key topics include:
-
Network defense fundamentals: OSI model, TCP/IP, and network architecture security
-
Network traffic analysis: detecting anomalies and suspicious activities using Wireshark, tcpdump, and other tools
-
Perimeter defense & firewalls: configuring access controls, IDS/IPS, and next-gen firewall policies
-
Endpoint security & hardening: securing devices, servers, and workstations
-
Threat detection & mitigation: identifying malware, ransomware, phishing, and insider attacks
-
Virtual private networks (VPNs): securing data in transit and ensuring remote access protection
-
Risk management & compliance: understanding ISO 27001, PCI-DSS, GDPR, and regulatory requirements
-
Incident response readiness: preparing for, responding to, and recovering from network intrusions
The course includes practice tests that simulate real-world network defense scenarios, such as mitigating DDoS attacks, detecting lateral movement within a compromised network, and responding to unauthorized access attempts. Each question includes detailed explanations to solidify your understanding of network security techniques.
By completing this course, you’ll be fully prepared to pass the CND exam (312-38) and ready for roles such as Network Security Administrator, SOC Analyst, Cybersecurity Specialist, or IT Security Engineer—enabling organizations to defend against evolving network-based cyber threats.
