The ever-increasing reliance on interconnected electrical protection systems necessitates a robust cybersecurity posture. Traditional perimeter-based security models, which rely on strong external defenses, have proven insufficient against sophisticated cyberattacks. Zero-trust security offers a new paradigm for securing electrical protection systems by emphasizing continuous verification and least privilege access control.This article explores the principles of zero-trust security and its application in securing electrical protection systems to minimize attack surfaces and prevent lateral movement within networks.

Understanding Zero-Trust Security

Zero-trust is a security model that operates on the principle of "never trust, always verify." Unlike traditional security models that enforce stringent defenses at the perimeter but assume trust within, zero-trust treats all users, devices, and network flows as potentially hostile, requiring verification at every stage of digital interaction.

Core Principles of Zero-Trust

• Least Privilege Access: Granting users and devices the minimum level of access necessary to perform...
