Microsoft Cybersecurity Architect (SC-100)Evaluate Governance Risk Compliance (GRC) technical strategies and security operations strategiesMedium
A global energy utility company operates critical infrastructure systems that are subject to strict regulatory compliance (e.g., NERC CIP) and require maximum uptime. The cybersecurity architect needs to implement a strategy to manage and control access to highly sensitive operational technology (OT) systems, ensuring that only authorized personnel and processes can perform critical actions, and that all privileged activities are logged and auditable. Which GRC technical strategy is MOST suitable for this environment?
- ADeploying a comprehensive Privileged Access Management (PAM) solution tailored for OT environments.
- BEstablishing a Data Loss Prevention (DLP) system to monitor data transfers from OT networks.
- CImplementing a standard Enterprise Identity and Access Management (IAM) solution.
- DUtilizing a Security Information and Event Management (SIEM) system for all OT logs.
Show answer & explanationAnswer & explanation
Correct answer: A. Deploying a comprehensive Privileged Access Management (PAM) solution tailored for OT environments.
A PAM solution, especially one tailored for OT, is crucial for managing, monitoring, and auditing privileged access to sensitive OT systems, directly addressing the need for strict control, logging, and auditability for regulatory compliance and uptime.
Why the other options are wrong
- B. DLP is for preventing data exfiltration and does not address the core need to manage, control, and audit privileged access to the OT systems.
- C. Standard IAM solutions manage general user access but often lack the granular control, session management, and specialized auditing capabilities required for highly sensitive privileged accounts in OT environments.
- D. While SIEM collects logs, it doesn't provide the active management, control, and enforcement over privileged access itself, which is the primary requirement.
Privileged Access Management (PAM) for OT
PAM for OT is a specialized solution that secures, manages, and monitors privileged accounts and access to operational technology systems, ensuring strict control, auditability, and compliance.
- Manages shared and administrative credentials.
- Enforces least privilege for critical OT systems.
- Records and audits privileged sessions.
- Supports specialized OT protocols and devices.
Memory trick: PAM is the 'Royal Guard' for 'OT's Crown Jewels'.
