DevSecOps Essentials (DSE) — Lesson 2: Secure Code, Dependencies, Secrets, APIs, Infrastructure as Code, and Review

Learning Objectives

• Explain the structures, services, data, settings, roles, and dependencies governing Secure Coding and Dependency Risk.
• Implement and validate Secret Management, Api Security, and Infrastructure As Code and Peer Review using reviewable evidence.
• Evaluate the condition where a control passes a basic check but fails during Api Security because Secret Management data, version, or dependency assumptions differ and select a proportionate corrective response.

Detailed Topics

• Secure Coding applied to the course scenario, expected behavior, dependencies, controls, and evidence.
• Dependency Risk applied to the course scenario, expected behavior, dependencies, controls, and evidence.
• Secret Management applied to the course scenario, expected behavior, dependencies, controls, and evidence.
• Api Security applied to the course scenario, expected behavior, dependencies, controls, and evidence.
• Infrastructure As Code and Peer Review applied to the course scenario, expected behavior, dependencies, controls, and evidence.

Instructor Demonstration

The instructor traces a product team must accelerate delivery while embedding proportionate security controls, preserving developer flow, and producing auditable evidence. The walkthrough connects tools, configuration or analysis logic, system messages, decisions, and evidence captured in the DevSecOps control map, secure-pipeline evidence, dependency report, and improvement backlog. It also tests the exception where a control passes a basic check but fails during Api Security because Secret Management data, version, 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 DevSecOps control map, secure-pipeline evidence, dependency report, 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 DevSecOps control map, secure-pipeline evidence, dependency report, 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 control passes a basic check but fails during Api Security because Secret Management data, version, 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 DevSecOps control map, secure-pipeline evidence, dependency report, 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 or operational behavior, and defend the outcome through the DevSecOps control map, secure-pipeline evidence, dependency report, and improvement backlog.
