 * 1) V15: Business Logic Verification Requirements


 * 1) Control Objective

Ensure that a verified application satisfies the following high level requirements:


 * The business logic flow is sequential and in order
 * Business logic includes limits to detect and prevent automated attacks, such as continuous small funds transfers, or adding a million friends one at a time, and so on.
 * High value business logic flows have considered abuse cases and malicious actors, and have protections against spoofing, tampering, repudiation, information disclosure, and elevation of privilege attacks.

 * **15.2** | Verify the application has business limits and correctly enforces on a per user basis, with configurable alerting and automated reactions to automated or unusual attack. | | ✓ | ✓ | 2.0 |
