Federal Regulatory Guidance

Threats to cyber security are capable of adversely impacting reliability of electrical power generation. Protection of critical infrastructures, which include the national electrical power grid and other essential utilities, are now considered a significant aspect of national security.

Compliance requirements define Critical Assets, on which reliability of the electrical power grid depends, and also defines Critical Cyber Assets (Information Processing systems) essential to the operation of the Critical Assets. Examples of Critical Cyber Assets at control centers and backup control centers include computer systems and networked facilities at master and remote sites that provide monitoring and control, automatic generation control, real-time power system modeling, and real-time inter-utility data exchange.

Critical Cyber Assets are wrapped in an electronic security perimeter, whose definition closely matches the definition of a network security domain used by the Department of Defense.

Owl one-way Cross Domain Solutions provide a method of secure access through the electronic security perimeter; enabling Critical Cyber Assets to share information with the outside world without risk of data corruption or loss of network integrity.

DualDiode® Technology from Owl provides a non-routable protocol break that is rendered in hardware and operates at the physical layer.




The Federal Information Security Management Act of 2002 (FISMA) recognizes the importance of information security to the economic and national security interests of the United States. FISMA also delegates specific duties and responsibilities to the Computer Security division of the National Institute for Standards and Technology (NIST) to provide guidance in securing Federal information systems.
NIST Special Publications in the 800 series present documents of general interest to the computer security community. NIST SP 800 publication numbers of particular interest include the following:




Effective Reliability Standards that are clear, consistent and technically sound, coupled with a strong standards enforcement program, form the foundation of NERC’s efforts to help maintain and improve the reliability of North America’s bulk power system. NERC provides a number of additional programs and services designed to support owners, operators and users of the bulk power system in their efforts to attain operational excellence.

These include identifying issues before they have a chance to become critical, sharing best practices, supporting training and education, monitoring the international electric grid, benchmarking performance to provide the industry with an objective lens through which to view itself.




The U.S. Nuclear Regulatory Commission (NRC) was created as an independent agency by Congress in 1974 to enable the nation to safely use radioactive materials for beneficial civilian purposes while ensuring that people and the environment are protected.

The NRC regulates commercial nuclear power plants and other uses of nuclear materials, such as in nuclear medicine, through licensing, inspection and enforcement of its requirements.




Owl is a member of the Nuclear Energy Institute (NEI). NEI is the policy organization of the nuclear energy and technologies industry and participates in both the national and global policy-making process.

NEI’s objective is to ensure the formation of policies that promote the beneficial uses of nuclear energy and technologies in the United States and around the world.
