Question 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?

Options:

A.

Messages received from third-party services are the likely source of the malicious content.

B.

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.

C.

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.

D.

None of the above.

Question 3

An IT enterprise has three domain service inventories that map to three different departments. Each service inventory uses a security token service (STS) based authentication broker to enable single sign-on for services within the respective service inventory boundary. The tokens used for all single sign-on mechanisms are based on SAML assertions. You are given a new requirement to extend this security architecture so that services from different domain service inventories can communicate. What new security mechanisms are required to fulfill this requirement?

Options:

A.

The individual authentication brokers need to be replaced with one single authentication broker so that one single token can be used by services across all domain service inventories.

B.

An additional authentication broker needs to be added in between each domain service inventory in order to enable communication between services using disparate security tokens.

C.

There is no need to introduce a new security mechanism. The individual domain service inventories need to be combined into a single enterprise service inventory. That way, the Service Perimeter Guard pattern can be applied so that services won't need to authenticate each other.

D.

There is no need to introduce a new security mechanism. The existing SAML tokens can be used by services across the domain service inventories as long as the existing authentication brokers are configured to issue service inventory-specific assertions for SAML tokens from specific domain service inventories.
