What is a full-time data network used for sharing operational security information?

A full-time data network used for sharing operational security information is recognized as the ISN, or the Integrated Security Network. The ISN provides a secure and efficient means for utilities and other entities within the electric power sector to exchange sensitive operational data and security-related information in real-time.

The significance of the ISN lies in its robust framework that enables stakeholders to coordinate responses to potential security threats and manage operational incidents effectively. By utilizing the ISN, organizations can enhance their situational awareness, enabling them to act swiftly to protect their infrastructure.

While the other options may relate to various aspects of the energy sector, they do not function specifically as a dedicated, full-time data network for operational security information sharing. The NERC hot line, for instance, serves as a reporting mechanism for suspicious activities but does not operate as a continuous data-sharing platform. Similarly, the FERC telecommunications INC is involved in regulatory communications, and OSL refers to something else within the sector, thus distinguishing the ISN as the appropriate choice for the described function.
