EC-Council Certified DevSecOps Engineer v1 — Lesson 2: Secure Code, Dependencies, Secrets, APIs, Infrastructure as Code, and Review

Learning Objectives

• Explain the roles, services, data, settings, dependencies, and decision criteria governing secure coding and dependency assurance.
• Implement and validate secret management, API security, and infrastructure as code using controlled evidence and clear acceptance criteria.
• Evaluate the condition where a basic control passes but API security fails because secret management data, configuration order, or dependency assumptions differ and select a proportionate corrective response.

Detailed Topics

• secure coding applied to the course scenario, expected behavior, dependencies, controls, risks, and evidence.
• dependency assurance applied to the course scenario, expected behavior, dependencies, controls, risks, and evidence.
• secret management applied to the course scenario, expected behavior, dependencies, controls, risks, and evidence.
• API security applied to the course scenario, expected behavior, dependencies, controls, risks, and evidence.
• infrastructure as code applied to the course scenario, expected behavior, dependencies, controls, risks, and evidence.

Instructor Demonstration

The instructor traces a product engineering team embedding security into an existing delivery pipeline without blocking releases or weakening auditability. The walkthrough connects tools, configurations or analysis logic, system messages, decisions, and evidence captured in the ECDE v1 threat model, pipeline-control map, security-test evidence, and improvement backlog. It also tests the exception where a basic control passes but API security fails because secret management data, configuration order, or dependency assumptions differ.

Hands-On Exercise

Complete a controlled, authorized EC-Council exercise covering Secure Code, Dependencies, Secrets, APIs, Infrastructure as Code, and Review and preserve the verified result in the ECDE v1 threat model, pipeline-control map, security-test evidence, and improvement backlog.

1. Confirm scope, authorization, prerequisites, versions, identities, dependencies, and acceptance criteria.
2. Execute the workflow while recording settings, outputs, events, decisions, and system messages.
3. Test normal behavior, one boundary condition, and the stated exception without targeting real third-party systems.
4. Document corrections, evidence, ownership, retest criteria, rollback or recovery, and handover actions.

Scenario Analysis

• Identify which object, service, policy, setting, or sequence most strongly influences secure coding.
• Compare two defensible responses and explain technical, security, operational, legal, and support trade-offs.
• Determine how the ECDE v1 threat model, pipeline-control map, security-test evidence, and improvement backlog should be approved, retained, retested, and updated.

Troubleshooting Guidance

Start where expected behavior first differs from the observed result. Check authorization, prerequisites, identity, configuration order, data quality, version compatibility, connectivity, status, resource limits, and evidence separately. Treat “a basic control passes but API security fails because secret management data, configuration order, or dependency assumptions differ” as a hypothesis until logs, settings, captured outputs, and retest outcomes confirm the cause.

Validation Checklist

• Required components, identities, permissions, settings, safety controls, and dependencies are present.
• The ECDE v1 threat model, pipeline-control map, security-test evidence, and improvement backlog connects each conclusion to objective, reviewable evidence.
• Normal processing, a boundary condition, dependency behavior, and the stated exception were tested.
• Corrections, ownership, retest criteria, rollback or recovery, documentation, and operational handover are complete.

Lesson Outcome

Learners can apply Secure Code, Dependencies, Secrets, APIs, Infrastructure as Code, and Review, explain the resulting security, governance, business, or operational behavior, and defend the outcome through the ECDE v1 threat model, pipeline-control map, security-test evidence, and improvement backlog.
