Safety Concerns of External Data Storage Devices in Operational Technology Settings
The National Institute of Standards and Technology (NIST) has announced a new initiative aimed at improving cybersecurity in operational technology (OT) environments. The OT Security Series, launched on August 14, 2025, is a part of the ongoing efforts by the NIST National Cybersecurity Center of Excellence (NCCoE) to provide simplified guidance for securing OT systems.
The focus of the OT Security Series is on providing guidance, not on offering specific products or services. The first document in the series, titled "Reducing the Cybersecurity Risks of Portable Storage Media in OT Environments" (NIST Special Publication (SP) 1334), offers cybersecurity considerations for OT operators and manufacturers to use USB devices securely.
USB storage devices, while convenient, pose potential cybersecurity risks for organizations using them in their OT environments. Portable storage media can transfer data physically to and from OT environments, making them a potential vector for cyber attacks. To reduce these risks, organizations can implement secure physical and logical controls on the access, storage, and usage of USB devices.
The NIST Special Publication (SP) 1334 provides practical cybersecurity guidelines for the use of USB devices in OT environments. It aims to help organizations in the secure use of USB devices within their OT environments, and offers strategies for securing the access, storage, and usage of USB devices in OT environments.
The OT Security Series is not limited to the secure use of USB devices in OT environments, but aims to cover a broader range of topics. It is intended to provide simplified guidance, not comprehensive cybersecurity solutions. For more detailed information, organizations are encouraged to consult existing NIST publications.
To provide feedback or suggestions for the OT Security Series, contact the NCCoE Manufacturing team at [email protected]. The OT Security Series is an additional resource for organizations, not a replacement for existing NIST publications.
The NCCoE is a program led by the NIST, a U.S. government agency under the Department of Commerce. The NCCoE develops practical cybersecurity solutions through public-private partnerships, and the OT Security Series is one of their latest contributions to improving cybersecurity in various industries.
In conclusion, the OT Security Series is a valuable resource for organizations looking to improve the cybersecurity of their OT systems. By following the guidelines provided in the series, organizations can mitigate cybersecurity risks associated with USB devices and ensure the secure use of these convenient tools in their OT environments.
