ISO/IEC 27034 Lead Application Security Implementer — Lesson 3: Secure Development, Verification, Validation, Release, and Operational Protection

Learning Objectives

• Interpret the requirements, principles, roles, and dependencies shaping secure development, verification, validation, release, and operational protection.
• Apply a practical workflow and create a reviewable secure delivery assurance package.
• Evaluate the exception where release approval proceeds despite unresolved validation findings and determine proportionate follow-up.

Detailed Topics

• Secure Development applied to the course scenario and expected evidence.
• Verification applied to the course scenario and expected evidence.
• Validation applied to the course scenario and expected evidence.
• Release applied to the course scenario and expected evidence.
• and Operational Protection applied to the course scenario and expected evidence.

Instructor Demonstration

The instructor traces a case involving a software organization integrating security into product governance, architecture, development, testing, release, and maintenance. The demonstration links decisions to objective evidence, records the result in secure delivery assurance package, and tests the condition where release approval proceeds despite unresolved validation findings.

Hands-On Exercise

Complete a controlled exercise covering Secure Development, Verification, Validation, Release, and Operational Protection. Confirm scope and responsibilities, examine the stated exception, reach a supported conclusion, and preserve the outcome in secure delivery assurance package.

1. Define the objective, boundaries, stakeholders, criteria, and expected work product.
2. Perform the activity while recording assumptions, observations, evidence, and decisions.
3. Test normal operation, the exception, and an escalation or follow-up condition.
4. Document conclusions, owners, deadlines, verification methods, and review triggers.

Scenario Analysis

• Identify the requirement or control with the strongest influence on the scenario outcome.
• Compare two defensible responses and explain their risk, operational, and evidence trade-offs.
• Decide how the secure delivery assurance package should be approved, retained, reviewed, and updated.

Troubleshooting Guidance

Start where expected practice and observed evidence first diverge. Separate a missing record from an ineffective process, distinguish unclear ownership from a control failure, and treat “release approval proceeds despite unresolved validation findings” as a hypothesis until tested against the applicable criteria and intended outcome.

Validation Checklist

• Scope, roles, criteria, stakeholders, dependencies, and intended outcomes are explicit.
• The secure delivery assurance package connects conclusions to objective, reviewable support.
• Normal operation, the stated exception, escalation, and follow-up were evaluated.
• Owners, due dates, verification methods, review triggers, and improvement actions are clear.

Lesson Outcome

Learners can apply Secure Development, Verification, Validation, Release, and Operational Protection, explain the reasoning used, and defend the result through secure delivery assurance package.
