Which of the following NIST assurance levels requires physical presence for identity proofing?Group of answer choicesAAL3IAL3IAL1AAL2

Break Down the Problem

1. Identify the NIST assurance levels from the given choices: AAL1, AAL2, AAL3, IAL1, and IAL3.
2. Determine which levels require physical presence for identity proofing.

Relevant Concepts

• NIST Assurance Levels: These levels indicate the degree of certainty in a person's identity which is required for specific applications.
• Identity Proofing: The process of verifying the identity of an individual, which can either be conducted remotely or require physical presence.

Analysis and Detail

1. AAL1: This level does not require a high level of assurance and can generally be achieved without physical presence.
2. AAL2: This level may involve identity proofing strategies that do not necessarily require physical presence, though they will offer higher assurance than AAL1.
3. AAL3: This is the highest level of assurance, and it typically requires strong identity proofing measures including physical presence to verify the identity.
4. IAL1: Similar to AAL1, this level usually does not require physical presence.
5. IAL3: This level is focused on identity proofing that mandates physical presence for verification.

Verify and Summarize

Based on the analysis, the levels that require physical presence for identity proofing are mainly AAL3 and IAL3. However, since the question specifically asks for assurance levels rather than identity assurance levels, we can conclude that AAL3 is the most commonly cited level requiring physical presence.

Final Answer

AAL3 and IAL3 require physical presence for identity proofing.
