The correct term for the situation where systems are shut down by malicious actors for a certain period of time is availability loss.

Explanation:

When a system is made unavailable due to malicious activities, users and services are unable to access applications, networks, or data that are essential for operations. This can have significant repercussions on businesses, leading to decreased productivity, revenue loss, and diminished customer trust. Availability loss specifically pertains to the downtime experienced by users and affects the overall usability of the IT infrastructure.

In contrast, service loss could refer to the specific functionalities being disrupted rather than the overall system availability. Data loss would involve the permanent disappearance of data, and monetary loss would be a consequence of unavailability or data loss and would not directly describe the period when systems are shut down.

Therefore, the answer is availability loss.
