What is the three-tiered approach to risk management described in NIST SP 800-37, Revision 1? Response:

NIST SP 800-37, Revision 1, defines a three-tiered approach to risk management, with Tier 1 being the Organization Level, which focuses on governance and organizational-wide risk policies. The subsequent tiers are Mission/Business Process Level (Tier 2) and Information System Level (Tier 3), creating a hierarchical strategy for risk management.

"Addresses/Requires (Tier 1)" is not a recognized tier or component of the NIST SP 800-37 risk management framework.

While "Mission/Business Process Level" is a tier (Tier 2), it is not Tier 1 according to NIST SP 800-37, Revision 1.

Choice D is identical to choice A in the provided text and identifies the correct first tier, but choice A is designated as the primary correct answer.
