Accounts, promotions and payment flows have different abuse risks. Application protection should complement correct server-side business rules.
Evaluation approach
Add RASP context to session and order assessment. Calculate prices, eligibility, stock and payment state on the server. Revalidate changed fields between basket and confirmation.
Application example
A new-customer promotion must use server records rather than a client flag. Suspicious device signals can prompt review without automatically treating everyone in one household as one person.
Limits and considerations
An authentic application can still abuse valid APIs at scale. RASP does not repair missing order rules.
Checks and decisions
- Calculate prices server-side
- Apply promotion rights atomically
- Keep flagged orders reviewable
Measure effects on legitimate purchases as well as reduced fraud.
