CDEXOS Overview: At the National Nuclear Security Administration (NNSA), the integration of information technology (IT) systems has become increasingly crucial for both manufacturing nuclear weapon components and ensuring the security of the weapons themselves. However, as cyber threats continue to evolve, it is imperative that the NNSA effectively manages the associated risks. In this article, we will explore the current state of cybersecurity in the nuclear weapon industry and highlight the steps being taken to mitigate potential vulnerabilities…Enjoy!

You need to evolve your Cybersecurity protection, but where do you start? CDEXOS helps organizations identify, protect and respond to cyber threats. Our mission prioritizes business decisions so you make informed decisions on data protection, cloud migration, and cybersecurity.
Identifying and Assessing Cyber Risks
The inventorying of systems vulnerable to cyber threats is an essential step towards effectively managing cybersecurity risks. While progress has been made, NNSA acknowledges that efforts to identify, assess, and mitigate cyber risks at the weapon and manufacturing equipment level are still in their early stages of development. The inventorying process involves the identification of critical operational technology (OT) systems and nuclear weapons IT systems, both of which play a significant role in the nuclear security enterprise.
Operational Technology (OT) Environment
In the OT environment, which encompasses manufacturing equipment and industrial control systems, the number of systems across NNSA’s sites runs into the hundreds of thousands. While preliminary steps have been taken, such as the development of an OT-specific guidebook for risk assessment and training, comprehensive risk assessment in the OT environment is still nascent. Currently, NNSA focuses on identifying critical OT capabilities at each site and conducting assessments on individual systems or components to gain valuable insights.
Nuclear Weapons IT Environment
The nuclear weapons IT environment involves a relatively smaller number of systems compared to the OT environment. Although an exact estimate is unavailable, NNSA acknowledges the lower number. To strengthen cybersecurity in this area, initiatives are underway to create an inventory of nuclear weapons IT systems and assess and mitigate associated cyber risks. This involves formulating precise definitions, developing a risk management framework, identifying gaps in existing engineering processes, and revising internal guidance accordingly.
Managing Cybersecurity Risks in Future Weapons
NNSA officials recognize that the nature of cyber risks can vary depending on the type of nuclear weapon. Preliminary assessments have shown that current weapons, due to their reliance on older technology, possess minimal IT that is vulnerable to cyber threats. However, as newer and more advanced weapons are expected to enter the stockpile after 2030, additional IT components will be included. To address this, each program responsible for these future weapons is actively considering approaches to effectively manage cybersecurity risks as an integral part of the design and development process.
SUMMARY
As the digital integration of systems within the nuclear weapon industry continues to advance, the importance of cybersecurity cannot be overstated. NNSA’s commitment to identifying and mitigating cyber risks is evident, although progress is still in the early stages. By focusing on inventorying vulnerable systems and implementing comprehensive risk management practices, NNSA is taking significant steps towards strengthening cybersecurity in the nuclear weapon industry. As technology evolves and newer weapons enter the stockpile, it is crucial that cybersecurity remains a top priority to ensure the safety and security of these critical assets.
