QUESTION NO: 1
Service A retrieves data from third-party services that reside outside the organizational boundary. The quality of the data provided by these third-party services is not guaranteed.
Service A contains exception shielding logic that checks all outgoing messages. It is discovered that service consumers are still sometimes receiving malicious content from Service A.
Because digital signatures are being used, it is confirmed that Service A is, in fact, the sender of these messages and that the messages are not being altered by any intermediaries. Why do messages from
Service A continue to contain malicious content?
A. None of the above.
B. Exception shielding logic needs to be used in conjunction with asymmetric encryption in order to guarantee that malicious content is not spread to service consumers.
C. Messages received from third-party services are the likely source of the malicious content.
D. Digital signatures alone are not sufficient. They need to be used in conjunction with asymmetric encryption in order to ensure that no intermediary can alter messages.
Answer: C
QUESTION NO: 2
A legacy system is used as a shared resource by a number of services within a service inventory. The services that access the legacy system use the same user account. The legacy system is also directly accessed by other applications that also use the same set of credentials as the services. It was recently reported that a program gained unauthorized access to confidential data in the legacy system. However, because all of the programs that access the legacy system use the same set of credentials, it is difficult to find out which program carried out the attack. How can another attack like this be avoided?
A. The Trusted Subsystem pattern can be applied to avoid direct access to the legacy system by any program except a designated service.
B. The Service Perimeter Guard pattern can be applied so that all programs that are not services are required to access the legacy system via a perimeter service.
C. The Message Screening pattern can be applied to monitor incoming request messages.
D. None of the above.
Answer: A
QUESTION NO: 3
A security architecture needs to be created in order to guarantee that messages that are sent to Service A must comply to a security policy that is published as part of Service A's service contract.
The application of which of the following patterns will fulfill this requirement?
A. Exception Shielding
B. None of the above
C. Message Screening
D. Brokered Authentication
Answer: B
QUESTION NO: 4
Within a service composition, two Web services are using certificates in order to ensure message integrity and sender's authenticity. The certificates are included with every message exchange. Recently, the performance of these message exchanges has degraded. How can the performance be improved without compromising message integrity and message authenticity?
A. Because the services are part of the same service composition, there are no message integrity or message authenticity requirements. Therefore, the certificates can be removed
B. Use WS-Trust based SAML tokens by introducing an authentication broker
C. Use WS-SecureConversation security context tokens that make use of session keys and symmetric cryptography
D. None of the above
Answer: C
QUESTION NO: 5
The Exception Shielding pattern was applied to the design of Service A.
During testing, it is revealed that Service A is disclosing sensitive error information in one of its response messages. How is this possible?
A. The Exception Shielding pattern states that, in case of an error, the service should not send back any message at all, because this would implicitly tell the service consumer that something has gone wrong, thereby exposing vulnerabilities.
B. None of the above.
C. The Trusted Subsystem pattern has already been applied to Service A, thereby conflicting with the application of the Exception Shielding pattern.
D. It is the Message Screening pattern, not the Exception Shielding pattern, that prevents a service from transmitting sensitive error information in response messages.
