Governance Models for IT/OT Security Compliance

Elements of Governance Models for IT/OT Security Compliance

Governance models for IT/OT security compliance typically include several key components¹²:

1. Policies: These are the rules that define what is expected from people and systems in terms of security.
2. Procedures: These are the steps to be followed to comply with the policies.
3. Controls: These are the mechanisms that enforce the policies and procedures.
4. Metrics and Key Performance Indicators (KPIs): These are used to measure the effectiveness of the policies, procedures, and controls.

In addition, there are three areas that any model should cover³:

1. Technical Architecture: This includes the design and configuration of the IT/OT systems.
2. Data Management: This involves how data is collected, stored, processed, and protected.
3. Information Security: This covers how information is protected from unauthorized access, use, disclosure, disruption, modification, or destruction.

Application to IT and OT Environments

IT Environments

In IT environments, a governance model enables organizations to define a structured process for enforcing security and compliance⁴. This process can be mirrored, modified, or changed based on organizational requirements⁴. Decisions around the provisioning, administration, stewardship, and offboarding of cloud resources are included in creating an effective governance model⁴.

OT Environments

In OT environments, governance refers to the framework and processes determining how OT systems are managed and secured². It encompasses questions of authority and accountability, crucial for minimizing cyber risk in operational processes². Strengthening cybersecurity governance and operating models across OT and IT teams helps clarify ownership, roles, and responsibilities related to protecting plant assets and fostering collaboration and coordination⁵.

Creating a Secure and Compliant Enterprise Environment

To create a secure and compliant enterprise environment, governance teams provide oversight and monitoring to sustain and improve security posture over time⁶. These teams also report compliance as required by regulating bodies⁶. Business goals and risk provide the best direction for security⁶. This direction ensures that security focuses their efforts on important matters for the organization⁶.

A governance, risk, and compliance (GRC) framework helps organizations to establish policies and practices that minimize compliance risk⁷. Specifically, IT and security GRC solutions are designed to harness up-to-date information about data and infrastructure as well as virtual, mobile, and cloud applications⁷.

In conclusion, governance models for IT/OT security compliance are essential for creating a secure and compliant enterprise environment. They provide a structured approach to managing and securing IT/OT systems, ensuring that all activities are aligned with the organization’s business goals and compliance requirements.
