Protecting access to physical infrastructure

This month saw the release of the NIST SP 800-82 Revision 3 document guide to operational technology (OT) security. The draft guides organisations on improving OT security, with emphasis on bespoke performance and safety needs. The document’s approach, in this way, allows for the unique circumstances of every OT system, accounting for different threats and risk tolerances in various critical infrastructure setups. Experts agree that, although not entirely perfect, the new document is effective in considering the unique needs of OT systems. Julia O’Toole describes it as “a step forward in the right direction.”
