What is a requirement of the Person or Entity Authentication Standard?

The Person or Entity Authentication Standard is part of the safeguards defined by the Health Insurance Portability and Accountability Act (HIPAA) to protect electronic protected health information (ePHI). The standard focuses on ensuring that organizations implement reasonable measures to verify the identities of individuals or entities accessing their systems.

The correct answer pertains to the requirements specified in this standard, which prioritize the establishment of robust authentication processes. Specifically, a requirement under this standard can include having a minimum password length to enhance security. Such measures prevent the use of overly simplistic passwords that can be easily guessed or cracked.

While other options offer various approaches to authentication — like two-factor authentication or single sign-on mechanisms — the key focus of the Person or Entity Authentication Standard involves ensuring that the authentication processes are sufficiently secure without necessarily mandating specific methods like multi-factor authentication or requiring the use of single sign-on systems for each session.

The mention of no unit level password may misconstrue the broader context, as it does not directly reference a fulfillment aspect of the standard itself; rather, it implies a lack of any precautions, which does not align with the standard's intent of safeguarding access. Therefore, recognizing the broader implications of secure password management, with minimum requirements in mind, aligns with the objectives of
