Which of the following is NOT one of the NIST functions to protect digital assets?

The NIST Cybersecurity Framework outlines five core functions aimed at helping organizations manage and mitigate cybersecurity risks, which are Identify, Protect, Detect, Respond, and Recover. Among these, "Execute" does not appear as one of the defined functions.

"Identify" involves understanding the organization's environment and the risks associated with their digital assets. "Protect" focuses on implementing safeguards to ensure the delivery of critical infrastructure services. "Recover" pertains to maintaining plans for resilience and restoring capabilities or services after a cybersecurity incident.

Since "Execute" is not one of these recognized functions, it stands out as the option that does not fit within the NIST framework for safeguarding digital assets. This distinction reinforces the importance of understanding the framework's structure and its focus on systematic approaches to cybersecurity risk management.
