Integration of Zero Trust 1 min read | Published on 16. January 2025 Vendor-News in OT environments The implementation of zero trust architectures is a paradigm shift that is increasingly finding its way into OT environments. The concept of “trust no one, check everything” provides a robust basis for preventing unauthorised access and increasing security in OT systems. Why Zero Trust for OT? OT environments are traditionally designed for availability, often at the expense of security. However, with increasing networking and the associated risks, it is essential to prioritise security. Zero Trust offers: -Strict access controls based on the identity and context of access. micro-segmentation to minimise attack surfaces. -Continuous monitoring and authentication. Practical steps for implementation: network segmentation: separation of critical OT systems from IT networks. real-time monitoring: use of modern technologies such as SIEM systems to recognise threats at an early stage. A concrete advantage: An energy supplier was able to contain a phishing attack by introducing Zero Trust, as the segmented networks prevented the attack from spreading. Such examples show how effective Zero Trust can be in OT environments. Back to the News.
