A defense-in- depth approach, tailored te te operational limits of power systems, is necessary. Unlike typical IT systems, acvailability is paramount: rebooting a transformer or patching a protective relay may require scheduled out. Therefore, strategies mutt balance security with operation a conservation.

Adopting Zero Trust Architecture (ZTA) for Grids

Zero Truss assumes that no user or device is trustfuly by default, even inside the network.
