Network breaches rarely start with a dramatic zero-day; they start with a misconfigured firewall rule, an unpatched endpoint, or a log nobody reviewed. This CND Certification Course is built around that reality. You will work inside live lab environments covering perimeter defense, cloud and virtualization security, endpoint hardening, log and traffic analysis, and incident response, using the same tools SOC teams and network administrators rely on daily. By the end, you will be prepared to sit the EC-Council 312-38 exam and to defend a real production network from day one.
Prerequisites
EC-Council does not enforce a strict prerequisite for the CND exam, but this course assumes some working familiarity with IT and networking concepts. You will get the most out of it if you already have:
- Basic understanding of TCP/IP, DNS, DHCP, and common network ports and protocols
- Familiarity with routing and switching fundamentals
- Comfort working from a command line (Windows and Linux)
- 6–12 months of IT, system administration, or networking exposure (recommended, not mandatory)
If you are completely new to networking, kodestree’s foundational networking module (included as a refresher in Week 1) will bring you up to speed before the core CND content begins.
Course Objectives
- Build a working, defense-first understanding of enterprise network architecture
- Configure and tune perimeter defenses, including firewalls, IDS/IPS, routers, and VPNs
- Harden endpoints across Windows, Linux, mobile, and IoT/OT devices
- Secure cloud (AWS, Azure, GCP) and virtualized environments against modern attack patterns
- Monitor, baseline, and analyze network traffic and logs to catch anomalies early
- Execute first-responder incident handling and basic forensic investigation steps
- Apply risk management, attack surface analysis, and threat intelligence to anticipate attacks before they land
- Walk into the EC-Council 312-38 exam with a clear, tested study plan
What You Will Learn
- Network defense fundamentals: the protect–detect–respond–predict lifecycle
- Administrative and technical network security controls, policies, and compliance alignment
- Firewall architecture, IDS/IPS deployment, and network perimeter design

- Application security fundamentals, including whitelisting and patch management
- Data security: encryption, DLP concepts, and secure data-at-rest/in-transit practices
- Virtual network security and secure configuration of virtualized infrastructure
- Cloud network security across AWS, Azure, and GCP shared-responsibility models
- Wireless network security, from encryption standards to rogue AP detection
- Network traffic monitoring, baselining, and anomaly detection
- Log management and SIEM-based log analysis for early threat detection
- Incident response workflows and first-responder forensic investigation
- Business continuity and disaster recovery (BC/DR) planning fundamentals
- Risk management and attack surface analysis
- Cyber threat intelligence (CTI) fundamentals for predictive defense
