Use cases
- A new application or API is approaching production.
- Authentication or authorization is changing.
- A product team needs security input during design rather than after release.
- A customer-facing application has accumulated dependencies or privileged functions that need review.
Review surface
- Authentication and account recovery
- Authorization and role boundaries
- API exposure and data handling
- Dependencies and secret handling
- CI/CD, deployment, and administrative access where in scope
Method
01Map trust boundaries, identities, sensitive actions, and data flows.
02Review the agreed architecture, configuration, and implementation evidence.
03Validate higher-risk assumptions using authorized non-destructive or active techniques as scoped.
04Translate findings into changes that product and engineering teams can verify.
Deliverables
- Architecture and application findings
- Authentication and authorization observations
- API and dependency risks
- Remediation notes for engineering teams
- Follow-up verification where agreed
Practice context
Application-security work sits within Technical Assessments & Defensive Engineering and is scoped around the application, API, identity, deployment, and data paths that actually need review.
Illustrative finding — not client data
Area
Account recovery
Observation
A privileged role can be recovered through a weaker path than its normal sign-in control.
Consequence
The recovery process can become the practical authentication boundary for the account.
Example action
Bring privileged recovery under equivalent identity verification, logging, and approval controls.
Scope
Engagement boundary
Application security scope does not automatically include every dependency, production environment, source repository, or external service. Those boundaries are agreed before review work starts.
