What is included in the FR-7 - Resource Availability category?

The Resource Availability category, specifically FR-7, focuses on ensuring that the necessary resources are available when needed to maintain the secure and reliable operation of the system. Emergency power is a critical component of resource availability because it ensures that critical systems can continue to operate in the event of a power failure or disruption. This capability is vital for preventing downtime and ensuring that essential functions remain operational, especially in industrial control systems where any interruption could lead to significant safety risks or operational impacts.

The other options, while important components of cybersecurity, do not directly relate to the concept of resource availability. Identification and authentication focus on user access control, data confidentiality pertains to protecting information from unauthorized disclosure, and malicious code protection is concerned with safeguarding against harmful software. Each of these elements plays a role in overall cybersecurity but does not specifically address the availability of resources like emergency power does.
