Critical infrastructure organizations usually have strong physical security to control who can enter buildings and sensitive areas. However, the operational technology (OT) networks, which manage industrial processes and equipment, often remain vulnerable and lack comparable access controls. This discrepancy exposes OT networks to potential cyber threats and unauthorized access, putting critical systems at risk.
The blog suggests implementing Zero Trust security models within OT environments to address these risks. Zero Trust assumes no implicit trust and requires continuous verification of users and devices before granting access. Applying this principle to OT networks can ensure digital access is controlled with the same rigor as physical entry points, reducing attack surfaces and preventing lateral movement by attackers.
Adopting Zero Trust in OT environments involves unique challenges due to legacy systems and the need for operational continuity. Nonetheless, the potential improvement in security posture can significantly mitigate risks, ensuring critical infrastructure resilience against cyber threats. The article highlights the importance of bridging physical and cyber security controls to protect sensitive operational environments.
