Which of the following is required by the E.O. 13587 to monitor employee use of classified networks?

E.O. 13587 establishes guidelines to enhance security and mitigate risks associated with classified information systems. The requirement for the capability to gather, integrate, and analyze threat-related information is crucial in monitoring employee use of classified networks. This capability allows organizations to proactively identify suspicious behavior, monitor access to sensitive data, and assess potential insider threats. By focusing on threat-related information, organizations can better protect national security interests, ensuring that classified networks are used appropriately and that any anomalies in employee behavior can be detected and addressed promptly.

The other options, while they may have their own merit in organizational management or performance, do not specifically fulfill the requirements set forth by E.O. 13587 concerning monitoring and managing insider threats. Regular performance reviews and enhanced training programs are important for employee development but do not directly relate to tracking classified network usage or analyzing threat intelligence. Monthly reporting of employee productivity focuses on performance metrics rather than security measures necessary for safeguarding classified information. Thus, option A stands out as the essential requirement for monitoring adherence to security protocols in classified environments.
