What describes Information Assurance (IA) and its relevance to IWO?

• A. IA protects information and information systems from authorized access, modification, or destruction; IWO ensures IA is embedded in IO planning and operations.
• B. IA is about physical security of facilities.
• C. IA focuses on data availability only.
• D. IA stands for International Alliance and guides cross-border operations.

Answer: (A)

Information Assurance is about protecting information and information systems from unauthorized access, modification, or destruction, while ensuring the information remains trustworthy and usable when needed. That means safeguarding confidentiality, maintaining integrity, and ensuring availability, along with appropriate controls like authentication and accountability.

For an Information Warfare Officer, IA isn’t a standalone tech concern; it’s woven into how information operations are planned and executed. Embedding IA in IO planning means you’re deliberately designing defenses, resilience, and response into the operation from the start—so decision-quality data, secure communications, and mission-critical information stay reliable even in the face of threats or disruption.

That description fits best because it captures both the protective aims of IA and its practical integration into IO work. IA isn’t only about physical security of facilities, nor is it limited to availability or misnamed as something like an International Alliance.
