Secure Software Development / Basic: outcomes, models, and decisions
Secure Software Development β Basic: outcomes, models, and decisions
Define protected outcomes, trust boundaries, requirements, bounded misuse cases, safe defaults, and reviewable design choices.
What you will learn
- Separate security activities, product properties, and supporting evidence.
- Choose a concrete risk question for a small fictional workshop service.
- Identify assets, actors, stores, processes, and external dependencies.
- Explain why a drawn boundary needs an associated trust decision.
Make security a lifecycle responsibility
Connect a software change to protected outcomes, accountable decisions, and evidence across its lifecycle.
Start learningMap assets, data flows, and trust boundaries
Build a small model that explains where authority and sensitive data change hands.
Start learningWrite verifiable security requirements
Translate a broad security concern into a bounded rule, refusal behavior, and evidence plan.
Start learningDesign misuse cases without operational attacks
Challenge business assumptions with safe local scenarios and explicit protected invariants.
Start learningDesign safe defaults and enforceable invariants
Choose explicit behavior for absent policy, dependency uncertainty, and state transitions.
Start learningRecord security decisions for useful review
Explain a design choice through context, alternatives, evidence, and residual risk.
