SOA Fundamental SOA Security Sample Questions:

Question #1

The manager of an IT department decides to split up an existing enterprise service
inventory into two domain service inventories. The public key used previously in the
enterprise service inventory can continue to be used in one of the domain service
inventories.

  • A. True
  • B. False
Reveal Solution  Discussion  0

Correct Answer: A  🗳️

Question #2

Service A hashes a message, resulting in message digest X.
Service A encrypts message
digest X with its private key, resulting in cipher text X1.
Service A sends the message and
X1 to Service B.
Service B hashes the message, resulting in message digest Y.
Service B
decrypts X1 with Service A's public key, recovering message digest X1.
Service B
compares X and Y and finds them not to be equal. This proves that;

  • A. public key cryptography was used
  • B. the message was altered
  • C. only Service A sent this particular message
  • D. All of the above
Reveal Solution  Discussion  0

Correct Answer: D  🗳️

Question #3

As part of Service Composition A, a service consumer needs to authenticate itself to four
different services. The Direct Authentication pattern was applied to each of these four
services, all of which share the same identity store. This identity store is also shared by a
number of additional services. As a result of increased usage, the identity store has
become a performance bottleneck. The resulting performance degradation is impacting
Service Composition A to the extent that it is causing problems. The security architecture
for Service Composition A needs to be improved in order to avoid further performance
degradation. However, any changes to the service composition architecture cannot break
any dependencies with the existing service consumer. Which of the following approaches
fulfills these requirements?

  • A. None of the above
  • B. Introduce dedicated identity stores so that each service in the service composition has
    its own copy of the identity information. This way, dependencies with the existing service
    consumer are not broken
  • C. Use a service agent between the four services and the centralized identity store in order
    to centralize the task of authentication. This way, load on the identity store is decreased
    and dependencies with the existing service consumer are not broken
  • D. Apply the Brokered Authentication pattern so that SAML tokens can be issued by a
    centralized authentication broker. This way, the existing service consumer does not need to
    re-authenticate itself over and over again

Correct Answer: B  🗳️

Question #4

Service A relies on a shared identity store. Service B has its own identity store. Service C
also has its own identity store, but must also access the shared identity store used by
Service A.
Which service has the least reduction in autonomy as a result of its relationship with identity store mechanism(s)?

  • A. Service C
  • B. Service B
  • C. The autonomy of all services is affected equally
  • D. Service A

Correct Answer: B  🗳️

Question #5

A valid signature issued by a certificate authority provides a guarantee that:

  • A. the certificate is not expired
  • B. the certificate is being used for an authorized purpose
  • C. None of the above.
  • D. the certificate authority can be trusted
