Computer Network Operations (CNO)
Computer Network Operations (CNO)
Computer Network Operations (CNO) encompasses offensive and defensive cyber operations as defined by the U.S. Department of Defense (DoD). It includes three primary areas of focus:
- Computer Network Attack (CNA): Offensive operations to disrupt or disable adversary networks.
- Computer Network Defense (CND): Measures to protect and secure critical systems.
- Computer Network Exploitation (CNE): Intelligence-gathering activities within adversary networks.
This page provides an overview of CNO, its pathways, prerequisites like the Computer Network Assessment Battery (CNAB), and additional resources to aid in preparation and career advancement.
Pathway to CNO Careers
Step 1: Passing the CNAB
The Computer Network Assessment Battery (CNAB) is a prerequisite evaluation for many CNO-related roles. It assesses foundational technical skills and cognitive abilities, ensuring readiness for advanced training. Key components include:
- Computer Networking Test: Focus on networking fundamentals like IP addressing and routing.
- Matrix Test: Evaluates pattern recognition and abstract reasoning.
- Work Background and Preferences Assessment: Gathers professional and technical experience relevant to CNO roles.
Step 2: Cyber Operations Training
After passing the CNAB, candidates undergo comprehensive training that covers:
- Network Security and Defense: Principles of securing and monitoring networks.
- Offensive Operations: Techniques in penetration testing, vulnerability exploitation, and malware deployment.
- Advanced Tools: Hands-on experience with industry tools and frameworks.
Step 3: Certification
Candidates often pursue certifications that validate their technical skills and knowledge:
- Certified Ethical Hacker (CEH)
- Offensive Security Certified Professional (OSCP)
- GIAC Penetration Tester (GPEN)
- Certified Information Systems Security Professional (CISSP)
Step 4: Assignment to Specialized Units
Graduates of CNO programs are typically assigned to specialized cyber units such as:
- NSA Cyber Operations
- U.S. Cyber Command
- Military Branch Cyber Teams (e.g., Army Cyber, Air Force Cyber Warfare Operator, Navy CWE)
