PHP Security — Lesson 3: Code Review, SAST, DAST, Dependencies, APIs, and Security Testing

Learning Objectives

• Explain the structures, services, data, settings, roles, and dependencies governing Php Code Review and Sast.
• Implement and validate Dast, Composer Dependencies, and Api Security and Test Triage using reviewable evidence.
• Evaluate the condition where analysts reach the wrong conclusion because Api Security and Test Triage evidence is incomplete and Sast context was not preserved and select a proportionate corrective response.

Detailed Topics

• Php Code Review applied to the course scenario, expected behavior, dependencies, controls, and evidence.
• Sast applied to the course scenario, expected behavior, dependencies, controls, and evidence.
• Dast applied to the course scenario, expected behavior, dependencies, controls, and evidence.
• Composer Dependencies applied to the course scenario, expected behavior, dependencies, controls, and evidence.
• Api Security and Test Triage applied to the course scenario, expected behavior, dependencies, controls, and evidence.

Instructor Demonstration

The instructor traces a development team must release a business application while preventing common weaknesses, proving control effectiveness, and maintaining secure delivery evidence. The walkthrough connects tools, configuration or analysis logic, system messages, decisions, and evidence captured in the PHP threat model, secure-code review, security-test evidence, and deployment checklist. It also tests the exception where analysts reach the wrong conclusion because Api Security and Test Triage evidence is incomplete and Sast context was not preserved.

Hands-On Exercise

Complete a controlled, authorized EC-Council exercise covering Code Review, SAST, DAST, Dependencies, APIs, and Security Testing and preserve the verified result in the PHP threat model, secure-code review, security-test evidence, and deployment checklist.

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 Php Code Review.
• Compare two defensible responses and explain technical, security, operational, legal, and support trade-offs.
• Determine how the PHP threat model, secure-code review, security-test evidence, and deployment checklist 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 “analysts reach the wrong conclusion because Api Security and Test Triage evidence is incomplete and Sast context was not preserved” 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 PHP threat model, secure-code review, security-test evidence, and deployment checklist 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 Code Review, SAST, DAST, Dependencies, APIs, and Security Testing, explain the resulting security or operational behavior, and defend the outcome through the PHP threat model, secure-code review, security-test evidence, and deployment checklist.
