6. The method of claim 1 , wherein the attack vector includes an attack to at least one of: Structured Query Language (SQL) injection, cross-site scripting, command injection, insecure randomness, header manipulation, and path manipulation.

7. A system comprising:

a processor; and

a non-transitory computer readable medium on which is stored instructions that when executed by the processor, cause the processor to:

receive, from a security test engine, a request that inquires whether a security activity of an application under test (AUT) occurred during an attack vector of a dynamic security test;

obtain a predefined listing of a plurality of application programming interfaces (APIs) that are each known to be associated with a defensive mechanism in response to a security threat;

determine that an API from among the plurality of APIs was used during the attack vector; and

send a message to the security test engine indicating that an appropriate defensive response to the attack vector was used during the attack vector.

8. The system of claim 7 , wherein the system includes the security test engine, and wherein the security test engine is to further send type information associated with the attack vector to a runtime agent executing at the processor, the runtime agent is further to identify and monitor use of the API based on the type information.

9. The system of claim 7 , wherein the system includes the security test engine, and wherein the security test engine is further to:

modify future attack vectors based on the indication that the appropriate defensive response was used.

10. The system of claim 9 , wherein to modify the future attack vectors, the security test engine is further to:

map a function call by the API with a field that is subject to the attack vector; and

ignore the field in the future attack vectors.

11. The system of claim 7 , wherein to send the message, the instructions, when executed by the processor, further cause the device to:

generate a trace response that includes a trace that associates an application request from the attack vector with a response to the application request from the AUT, the message including the trace response.

12. The system of claim 7 , wherein the system includes the security test engine, and wherein the security test engine is to further generate a vulnerability report for the dynamic security test.

13. The system of claim 12 , wherein to generate the vulnerability report, the security test engine is further to include a reporting that the appropriate defensive response to the attack vector was used.

14. The system of claim 9 , wherein to modify the future attack vectors, the security test engine is further to:

identify attack vectors among the future attack vectors that are known to be blocked by use of the API; and

ignore the identified attack vectors.

15. The system of claim 7 , wherein the attack vector includes an attack to at least one of: Structured Query Language (SQL) injection, cross-site scripting, command injection, insecure randomness, header manipulation, and path manipulation.

16. A non-transitory machine-readable storage medium storing instructions that, when executed by a processor of a device, cause the device to:

monitor execution of an application under test (AUT) to execute on a server during a dynamic security test of the AUT;

receive an indication that an attack vector is to be performed on the AUT;

obtain a predefined listing of a plurality of application programming interfaces (APIs) that are each known to be associated with a defensive mechanism in response to a security threat;

determine that an API from among the plurality of APIs was used during the attack vector; and

send a message to the dynamic security test indicating that an appropriate defensive response to the attack vector was used by the AUT based on the determination that the API was used.

17. The non-transitory machine-readable storage medium of claim 16 , further comprising instructions that, when executed by the processor, cause the device to:

determine that the attack vector was unsuccessful, wherein the message is sent responsive to the determination that the attack vector was unsuccessful.

18. The non-transitory machine-readable storage medium of claim 16 , wherein an agent executing on the device monitors the AUT and determines that the API was used.

19. The system of claim 7 , wherein the instructions, when executed by the processor, further cause the device to:

receive, from the security test engine, an indication of a type of vulnerability that the attack vector is to attempt to find;

identify a first defensive mechanism that is to respond to the type of vulnerability;

identify the plurality of APIs associated with the first defense mechanism; and

monitor the plurality of APIs.
