About This Domain
Domain 4 — Network Intrusion Analysis — accounts for 20% of the CYBEROPS certification exam. This domain evaluates your understanding of tcp/ip protocol exploitation and analysis, dns-based attacks (dns spoofing, tunneling), web application attacks (sql injection, xss), and related concepts. Domain 4 covers network-based attack analysis, protocol exploitation, and using network security tools to detect and analyze intrusions. To pass this section you need practical knowledge of how these services and patterns work together in real-world architectures.
What You'll Be Tested On
- TCP/IP protocol exploitation and analysis
- DNS-based attacks (DNS spoofing, tunneling)
- Web application attacks (SQL injection, XSS)
- IDS/IPS rule analysis (Snort rules)
- Network-based indicators of compromise

Study Strategy for Domain 4
While 20% might seem like a smaller portion of the exam, every point counts toward the passing score. Focus on understanding core concepts and common exam scenarios for this domain.
Exam Tips for Domain 4
Know the TCP 3-way handshake and what SYN flood, RST attacks look like in packet captures.
Understand Snort rule syntax: action protocol src_ip src_port -> dst_ip dst_port (options).
DNS tunneling uses DNS queries to exfiltrate data — look for unusually long subdomain names.
