Service A is an agnostic service that is part of a complex service composition that relies on the use of several intermediaries for message routing purposes. Due to a recent malicious intermediary attack, public key cryptography and digital signatures have been added to Service A . Subsequently, the attacks stop. However, legitimate service consumers are experiencing latency when interacting with services from this complex service composition. Following an investigation, it is discovered that Service A has increased its system resource consumption in order to perform its new security-related functions. How can you improve Service A's performance without compromising its security requirements and without introducing new security mechanisms?

Service A has recently been the victim of XPath injection attacks. Messages sent between Service A and Service C have traditionally been protected via transport-layer security. A redesign of the service composition architecture introduces Service B, which is positioned as an intermediary service between Service A and Service C . The Message Screening pattern was applied to the design of Service B . As part of the new service composition architecture, transport-layer security is replaced with message-layer security for all services, but Service A and Service C continue to share the same encryption key. After the new service composition goes live, Service A continues to be subjected to XPath injection attacks. What is the reason for this?
