A data classification policy can BEST be described as which type of security control?

A data classification policy is fundamentally an administrative security control because it establishes the guidelines and procedures for handling and managing different types of data based on their sensitivity and importance. Such policies typically outline how data should be classified, who has permission to access certain data classifications, and the safeguards required for each classification level. This can involve training employees on data handling and defining protocols for data sharing, storage, and destruction.

Administrative controls are all about managing the organizational processes that guide the implementation of security measures. They focus on policies, procedures, and training rather than on physical environments or technical systems. By properly classifying data, organizations can ensure that appropriate security measures are placed according to the risk associated with various data types, thereby efficiently mitigating the potential for data breaches and misuse.

In contrast, physical security controls pertain to tangible measures to protect physical assets, while technical security controls involve the use of technology to protect data and systems, such as firewalls and encryption. Application security controls are specific to securing software applications against threats and vulnerabilities. Therefore, the classification policy's reliance on procedures, management, and oversight to maintain data security aligns it more closely with administrative security controls.
