Which of the following is NOT a type of threat faced by Integrated Defense Systems?

Integrated Defense Systems are designed to protect critical infrastructure and important assets from various types of threats. Among the types listed, cyber attacks, physical attacks, and natural disasters are all relevant threats that such systems are built to defend against.

Cyber attacks represent risks originating from malicious activities targeting digital systems and networks, potentially affecting data integrity and operational capabilities. Physical attacks encompass threats involving direct assaults on facilities, equipment, or personnel, necessitating protection measures against intruders or hostile forces. Natural disasters include external events like earthquakes, floods, or hurricanes that could impair functionality and safety, which systems are often designed to withstand or respond to.

In contrast, financial audits, while important for organizational oversight and compliance, do not pose a direct threat to the operational integrity or security of Integrated Defense Systems. They pertain more to fiscal responsibility and governance rather than physical or cyber security, establishing them as unrelated to the primary threats the systems aim to mitigate. Thus, the correct choice of “not a type of threat” accurately reflects this distinction.
