Which system is designed to ensure information security in defense operations?

The correct answer is the CDS, which stands for Command and Control Decision Support. This system plays a critical role in military operations by ensuring information security through robust data management and communication protocols. The main function of CDS is to facilitate secure and effective decision-making for commanders in defense operations. It achieves this by integrating data from various sources, maintaining the confidentiality and integrity of sensitive information, and providing real-time analysis to support operational decisions.

The significance of information security in defense operations cannot be overstated, as it protects vital intelligence from potential adversaries and ensures that commanders have access to accurate and secure information when making tactical and strategic decisions.

Each of the other systems listed has its own primary functions that may engage with information security; however, they do not specifically focus on secure information management in the same comprehensive way that the CDS does. Other systems may be more targeted towards battlefield management, threat assessment, or situational awareness without the same emphasis on protecting sensitive command information.
