The National Institute of Standards and Technology (NIST) has released a special publication that provides guidance and best practices for electric utilities to securely and efficiently manage access to the networked devices and facilities on which power generation, transmission, and distribution depend. According to NIST, such guidance is especially necessary now given the challenges posed by the convergence of OT and IT departments. If not properly managed, this convergence can lead to a lack of overall traceability and accountability, an increased risk of attack and service disruption, and an inability to identify potential sources of a problem or attack.
