QUESTION NO: 1
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: 2
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: 3
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: 4
The Service Perimeter Guard pattern has been applied to help avoid denial of service attacks for a service inventory. As a result, services within the service inventory are only accessible via a perimeter service However, denial of service attacks continue to succeed and services within the service inventory become unavailable to external service consumers. What is the likely cause of this?
A. The application of the Service Perimeter Guard pattern needs to be combined with the application of the Message Screening pattern in order to mitigate denial of service attacks.
B. The Service Perimeter Guard pattern does not help avoid denial of service attacks.
C. The Trusted Subsystem pattern should have been applied so that each service has a dedicated trusted subsystem.
D. The perimeter service itself is the victim of denial of service attacks. As a result, none of the services inside the service inventory can be accessed by external service consumers.
Answer: D
QUESTION NO: 5
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
