Lead SCADA Security Manager Training — Lesson 3: Governing Access, Remote Support, Patch, Supplier, Backup, and Monitoring Controls

Learning Objectives

• Interpret the purpose, responsibilities, inputs, and decision points shaping governing access, remote support, patch, supplier, backup, and monitoring controls.
• Apply the workflow and produce SCADA operational control evidence pack that another practitioner can review.
• Analyze “vendor access remains enabled after maintenance” and recommend a proportionate, evidence-based response.

Detailed Topics

• identity management
• remote access
• patch management
• supplier assurance
• configuration control
• backup
• network monitoring
• change management
• Governance, competence, communication, documentation, validation, risk, and follow-up considerations

Instructor Demonstration

The instructor demonstrates the governing access, remote support, patch, supplier, backup, and monitoring controls workflow, identifies applicable responsibilities, records checkpoints in SCADA operational control evidence pack, and contrasts the accepted state with a condition where vendor access remains enabled after maintenance.

Hands-On Exercise

Complete a controlled implementation, management, audit, assessment, foundation, introduction, awareness, or transition exercise for Governing Access, Remote Support, Patch, Supplier, Backup, and Monitoring Controls. Establish scope and criteria, collect or create evidence, examine “vendor access remains enabled after maintenance,” reach a supported conclusion, and preserve the result in SCADA operational control evidence pack.

1. Confirm objectives, scope, roles, criteria, stakeholders, and expected outputs.
2. Perform the planned activities while recording assumptions, evidence, and decisions.
3. Test a normal case, an exception, and a follow-up or improvement condition.
4. Document conclusions, owners, due dates, escalation, and verification requirements.

Scenario Analysis

• Identify the requirement or principle with the strongest influence on governing access, remote support, patch, supplier, backup, and monitoring controls.
• Compare two defensible responses and explain their governance, risk, and evidence trade-offs.
• Determine how the SCADA operational control evidence pack should be approved, retained, reviewed, and updated.

Troubleshooting Guidance

Separate missing evidence from ineffective practice, and distinguish a documentation issue from a control, process, governance, or competence failure. Use SCADA operational control evidence pack to trace the earliest divergence. Treat “vendor access remains enabled after maintenance” as a hypothesis until the response is validated against the applicable requirement and intended outcome.

Validation Checklist

• The scope, criteria, stakeholders, and intended outcome for governing access, remote support, patch, supplier, backup, and monitoring controls are explicit.
• The SCADA operational control evidence pack links statements and decisions to objective, reviewable support.
• Responsibilities, competence, communication, risk, legal duties, and change impact were considered where relevant.
• Findings, corrective actions, monitoring, review triggers, and improvement ownership are clear.

Lesson Outcome

Learners can apply Governing Access, Remote Support, Patch, Supplier, Backup, and Monitoring Controls, explain the reasoning used, and defend the result through SCADA operational control evidence pack.
