From understanding the challenges of disparate OT protocols and the increasing convergence with IT to grappling with the monumental role of human error, our latest interview with Rohit Bohara, CTO at asvin, delves deep into the landscape of OT security.

Can you comment on the challenge of creating disparate security systems for OT environments considering the variety of OT protocols? How does the difference in standardization between IT and OT systems add to this complexity?

Organizations can take multiple steps to mitigate risks of human errors, such as effective cyber security awareness, adequate training of personnel, effective password policies, clear written procedures, multi-factor authentication, role-based access control, regular security audits, detailed documentation, create security culture.

In the face of these myriad OT security threats, how effective is the zero-trust approach in securing OT systems?

Principles of zero-trust approach, verify identity, assign least privilege, micro-segmentation, continuous monitoring, automated threat management, encryption must be adapted to OT systems to minimize the potential impact of security threats.

Can you discuss how the Industrial Control Systems Cyber Emergency Response Team and standards such as ISA/IEC-62443 or ISA-99 can aid in addressing OT security threats?
