What system is composed of specialized software and hardware for integrated information assurance?

The system that is composed of specialized software and hardware for integrated information assurance is commonly recognized as the CDS (Common Data Services). This system is designed to effectively manage, protect, and assure the integrity, availability, and confidentiality of data within a unified infrastructure.

The CDS integrates various elements of information assurance, allowing for a comprehensive approach to security that includes both hardware and software components. It focuses on safeguarding sensitive information through enhanced monitoring, access controls, and risk management practices, thus providing a robust environment where data can be shared and utilized securely among users.

In contrast, other options such as GCCS-A/J, DRRS-A, and DCGS-A serve different purposes related to command and control systems, reporting and resource management, and intelligence gathering, respectively. They are not specifically designed with an emphasis solely on integrated information assurance as the CDS is, which underscores why CDS is the most suitable answer in this context.
