V18: API and Web Service Verification Requirements
Control Objective
Ensure that a verified application that uses RESTful or SOAP based web services has:
- Adequate authentication, session management and authorization of all web services
- Input validation of all parameters that transit from a lower to higher trust level
- Basic interoperability of SOAP web services layer to promote API use
Security Verification Requirements
| # | Description | L1 | L2 | L3 | |
|---|---|---|---|---|---|
| 18.1 | Verify that the same encoding style is used between the client and the server. | ✓ | ✓ | ✓ | 3.0 |
| 18.2 | Verify that access to administration and management functions within the Web Service Application is limited to web service administrators. | ✓ | ✓ | ✓ | 3.0 |
| 18.3 | Verify that XML or JSON schema is in place and verified before accepting input. | ✓ | ✓ | ✓ | 3.0 |
| 18.4 | Verify that all input is limited to an appropriate size limit. | ✓ | ✓ | ✓ | 3.0 |
| 18.5 | Verify that SOAP based web services are compliant with Web Services-Interoperability (WS-I) Basic Profile at minimum. This essentially means TLS encryption. | ✓ | ✓ | ✓ | 3.0.1 |
| 18.7 | Verify that the REST service is protected from Cross-Site Request Forgery via the use of at least one or more of the following: double submit cookie pattern, CSRF nonces, ORIGIN request header checks, and referrer request header checks. | ✓ | ✓ | ✓ | 3.0.1 |
| 18.8 | Verify the REST service explicitly check the incoming Content-Type to be the expected one, such as application/xml or application/json. | ✓ | ✓ | 3.0 | |
| 18.9 | Verify that the message payload is signed to ensure reliable transport between client and service, using JSON Web Signing or WS-Security for SOAP requests. | ✓ | ✓ | 3.0.1 | |
| 18.10 | Verify that alternative and less secure access paths do not exist. | ✓ | ✓ | 3.0 |
