What is the key requirement of immutability in cyber recovery?

Immutability in cyber recovery refers specifically to the principle that data cannot be changed or deleted once it has been recorded. This ensures that the data remains in its original state, providing a reliable foundation for recovery operations in the event of a cyber attack, data breach, or accidental deletion. By making data immutable, organizations can protect critical information from modification or destruction, which is essential for maintaining data integrity during recovery processes.

This characteristic is crucial because if data could be altered or removed, it would compromise the recovery efforts, making it difficult to restore a reliable version of the data. The integrity of backup copies is foundational for organizations to ensure business continuity and regulatory compliance.

In contrast, while accessibility, immediate recoverability, and constant monitoring are important components of a robust cyber recovery strategy, they do not capture the essence of immutability. The core requirement hinges specifically on data remaining unchanged and undeletable, ensuring that it can serve as a trustworthy resource during recovery scenarios.
