Where can Thomas find the standards his insider threat program must meet?

The correct answer is relevant because Executive Order 13587 specifically addresses the requirement for federal agencies to develop insider threat programs. It outlines standards and guidelines that organizations must follow to protect sensitive information and mitigate potential insider threats. This Executive Order forms a foundational policy framework aimed at improving the security of government systems and provides a clear directive on how insider threats should be managed.

While other options like internal policies or industry standards publications may provide useful guidance or information, they miss the authoritative context that comes from one of the highest levels of policy in the federal government. Online forums and community discussions, although they may provide insights or anecdotal experiences, do not establish formal standards or requirements that organizations must adhere to. Therefore, for a program that seeks to align with established protocols set forth by government mandates, Executive Order 13587 is the most direct and relevant source.
