Which of the following is a responsibility under administrative safeguards?

The assignment of security responsibilities is indeed a key component of administrative safeguards. Administrative safeguards are crucial for the protection of sensitive information in healthcare settings, as they involve the policies and procedures that manage the selection, development, implementation, and maintenance of security measures.

Assigning security responsibilities ensures that specific individuals or teams are accountable for managing security measures and protocols within the organization. This allocation of roles helps to establish clear lines of responsibility, enhances compliance with regulations such as HIPAA, and supports the overall security framework by ensuring that trained personnel are designated to oversee specific security tasks.

In contrast, controlled physical access and encryption of data are categorized under physical safeguards and technical safeguards, respectively. Controlled physical access deals with physical measures to protect facilities, while encryption secures data during transmission and storage, focusing more on the technical aspect of safeguarding information. Thus, the correct answer emphasizes the importance of administrative measures in establishing accountability and promoting a culture of compliance and security within healthcare organizations.
