Who oversees and manages the information security program?

The correct choice is guided by the role of the Information Security Oversight Office (ISOO), which directly oversees and manages the information security program within the federal government. The ISOO operates under the National Archives and Records Administration (NARA) and is responsible for ensuring that the government properly classifies, declassifies, and handles sensitive information in accordance with established regulations and standards.

The ISOO's primary responsibilities include monitoring the compliance of executive branch agencies with information security policies, conducting oversight of the government-wide security program, and providing guidance regarding the implementation of statutory and regulatory requirements related to information security. This role is critical for maintaining the integrity and security of sensitive information and ensuring that the information security practices align with national security interests.

While other entities, such as the National Security Agency or the broader Intelligence Community, play important roles in protecting national security and information, they do not specifically oversee the information security program as defined by federal regulations. The Department of Justice also has a role in legal aspects of information handling but is not responsible for managing the overarching information security program across the federal government. Thus, ISOO's focused oversight and management position it as the correct choice for this question.
