Which of the following security awareness training is BEST suited for data owners who are concerned with protecting the confidentiality of their data?

Social networking use training addresses appropriate employee behavior on social media platforms and does not specifically help data owners classify or protect sensitive data.

Personally owned device policy training covers BYOD security rules and is relevant to endpoint management, not data classification by owners.

Tailgating awareness training focuses on physical access control and preventing unauthorized personnel from entering secured areas, not on data confidentiality classification.

Data owners are responsible for determining how sensitive their data is and what protections it requires. Information classification training teaches them to categorize data (e.g., public, internal, confidential, restricted) so appropriate access controls, handling procedures, and sharing restrictions can be applied, which directly addresses the goal of protecting data confidentiality.
