Certified ISO/IEC 27034 Foundation Training — Lesson 3: Operating Secure Development, Acquisition, Testing, Deployment, and Operations

Learning Objectives

• Interpret the purpose, responsibilities, inputs, and decision points shaping operating secure development, acquisition, testing, deployment, and operations.
• Apply the workflow and produce application lifecycle control exercise that another practitioner can review.
• Analyze “a release bypasses required security testing” and recommend a proportionate, evidence-based response.

Detailed Topics

• secure development
• supplier acquisition
• security testing
• release controls
• deployment security
• operational monitoring
• vulnerability handling
• change management
• Governance, competence, communication, documentation, validation, risk, and follow-up considerations

Instructor Demonstration

The instructor demonstrates the operating secure development, acquisition, testing, deployment, and operations workflow, identifies applicable responsibilities, records checkpoints in application lifecycle control exercise, and contrasts the accepted state with a condition where a release bypasses required security testing.

Hands-On Exercise

Complete a controlled implementation, management, audit, assessment, foundation, introduction, awareness, or transition exercise for Operating Secure Development, Acquisition, Testing, Deployment, and Operations. Establish scope and criteria, collect or create evidence, examine “a release bypasses required security testing,” reach a supported conclusion, and preserve the result in application lifecycle control exercise.

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 operating secure development, acquisition, testing, deployment, and operations.
• Compare two defensible responses and explain their governance, risk, and evidence trade-offs.
• Determine how the application lifecycle control exercise 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 application lifecycle control exercise to trace the earliest divergence. Treat “a release bypasses required security testing” 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 operating secure development, acquisition, testing, deployment, and operations are explicit.
• The application lifecycle control exercise 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 Operating Secure Development, Acquisition, Testing, Deployment, and Operations, explain the reasoning used, and defend the result through application lifecycle control exercise.
