Which of the following is NOT considered a physical safeguard for the security rule?

The use of encryption software is primarily a technical safeguard rather than a physical safeguard. Physical safeguards are measures taken to protect the physical spaces where electronic information is stored or processed, such as controlling access to workspaces, securing access to buildings, and implementing controls over devices and media. These physical measures prevent unauthorized access and ensure that sensitive information remains secure within the physical environment.

In contrast, encryption software protects data itself by converting it into a secure format that can only be read or processed by individuals who have the appropriate decryption keys. While crucial for data security, encryption does not directly address how physical access to spaces or media is managed. Understanding the distinction between different types of safeguards—physical, technical, and administrative—is essential in implementing a comprehensive security strategy for information protection.
