Cybersecurity module

Secure SDLC

Secure delivery is more repeatable when expectations, checks, and ownership are embedded in the normal flow of change.

What changes after this module

Build security into planning, coding, review, release, and learning loops so control work happens with delivery instead of after it.

Outcome promise

  • Explain how security should appear across the software delivery lifecycle.
  • Identify one missing security activity that should be part of normal delivery.

Core model

Use the diagram and terms below as the minimum model you should be able to explain after this module. If you cannot explain the model in plain language, pause here before you move on.

Key terms

SDLC
The lifecycle through which software is planned, built, released, and maintained.
Shift left
Moving useful security work earlier in delivery where change is cheaper.

Check yourself

Answer the prompt before you reveal the check. If you cannot answer it in your own words, revisit the model and the terms once more.

Quick check

Why is secure delivery more than just running scanners in CI?

Reveal the answer check

Because it also depends on planning, ownership, design review, release control, runtime learning, and how findings actually get resolved.

Reflection and evidence

Keep the evidence small. One honest reflection and one small artefact is enough to show that the learning changed how you describe, check, or design something.

Reflection prompt

Think of one delivery team. What security activity is missing from its normal routine today?

Artefact

A short secure-SDLC map for one team, product, or service.

Optional deeper practice

Open the workspace and place security checks across one delivery lifecycle instead of stacking them all at release time.

Move through the course

Keep the flow predictable. Stay with the stage sequence unless you have a clear reason to jump around.
