NO.1 Service A exchanges messages with Service B multiple times during the same runtime service activity.
Communication between Services A and B has been secured using transport-layer security. With each
service request message sent to Service B (1A. IB), Service A includes an
X.509 certificate, signed by an external Certificate Authority (CA). Service B validates the certificate by
retrieving the public key of the CA (2A. 2B) and verifying the digital signature of the
X.509 certificate. Service B then performs a certificate revocation check against a separate external CA
repository (3A, 3B). No intermediary service agents reside between Service A and Service B.
To fulfill a new security requirement, Service A needs to be able to verify that the response message sent
by Service B has not been modified during transit. Secondly, the runtime performance between Services
A and B has been unacceptably poor and therefore must be improved without losing the ability to verify
Service A's security credentials. It has been determined that the latency is being caused by redundant
security processing carried out by Service B.
Which of the following statements describes a solution that fulfills these requirements?
A. Apply the Trusted Subsystem pattern to introduce a utility service that performs the security processing
instead of Service B. The utility service can verify the security credentials of request messages from
Service A and digitally sign messages sent to Service A to enable verification of message integrity.
Furthermore, the utility service can perform the verification of security credentials submitted by Service A
only once per runtime service activity. After the first messageexchange, it can issue a SAML token to
Service A that gets stored within the current session. Service A can then use this session-based token
with subsequent message exchange. Because SAML tokens have a very small validity period (in contrast
to X.509 certificates), there is no need to perform a revocation check with every message exchange.
B. Service B needs to be redesigned so that it performs the verification of request messages from Service
A only for the first message exchange during the runtime service activity. Thereafter, it can issue a SAML
token to Service A that gets stored within the current session. Service A then uses this session-based
token with subsequent message exchanges. Because SAML tokens have a very small validity period (in
contrast to X.509 certificates), there is no need to perform a revocation check with every message
exchange.
C. WS-SecurityPolicy transport binding assertions can be used to improve performance via
transport-layer security The use of symmetric keys can keep the encryption and decryption overhead to a
minimum, which will further reduce the latency between Service A and Service B. By encrypting the
messages, attackers cannot modify message contents, so no additional actions for integrity verification
are needed.
D. The Data Origin Authentication pattern can be applied together with the Service Perimeter Guard
pattern to establish a perimeter service that can verify incoming request messages sent to Service B and
to filter response messages sent to Service A. The repository containing the verification information about
the Certificate Authorities can be replicated in the trust domain of the perimeter service. When access is
requested by Service A, the perimeter service evaluates submitted security credentials by checking them
against the locally replicated repository. Furthermore, it can encrypt messages sent to Service A by
Service B. and attach a signed hash value.

NO.2 Service Consumer A sends a request message to Service A (1) after which Service A retrieves financial
data from Database A (2). Service A then sends a request message with the retrieved data to Service B
(3). Service B exchanges messages with Service C (4) and Service D (5), which perform a series of
calculations on the data and return the results to Service A. Service A uses these results to update
Database A (7) and finally sends a response message to Service Consumer A (8). Component B has
direct, independent access to Database A and is fully trusted by Database A. Both Component B and
Database A reside within Organization A. Service Consumer A and Services A, B, C, and D are external to
the organizational boundary of Organization A.
Component B is considered a mission critical program that requires guaranteed access to and fast
response from Database A. Service A was recently the victim of a denial of service attack, which resulted
in Database A becoming unavailable for extended periods of time (which further compromised
Component B). Additionally, Services B, C, and D have repeatedly been victims of malicious intermediary
attacks, which have further destabilized the performance of Service A.
How can this architecture be improved to prevent these attacks?
A. A utility service is created to encapsulate Database A and to assume responsibility for authenticating all
access to the database by Service A and any other service consumers. Due to the mission critical
requirements of Component B, the utility service further contains logic that strictly limits the amount of
concurrent requests made to Database A from outside the organizational boundary. The Data
Confidentiality and Data Origin Authentication patterns are applied to all message exchanged within the
external service composition in order to establish message-layer security.
B. Service Consumer A generates a private/public key pair and sends this public key and identity
information to Service A. Service A generates its own private/public key pair and sends it back to Service
Consumer A. Service Consumer A uses the public key of Service A to encrypt a randomly generated
session key and then sign the encrypted session key with the private key. The encrypted, signed session
key is sent to Service A. Now, this session key can be used for secure message-layer communication
between Service Consumer A and Service A. The Service Perimeter Guard pattern is applied to establish
a perimeter service that encapsulates Database A in order to authenticate all external access requests.
C. Services B, C, and D randomly generate Session Key K, and use this key to encrypt request and
response messages with symmetric encryption. Session Key K is further encrypted itself asymmetrically.
When each service acts as a service consumer by invoking another service, it decrypts the encrypted
Session Key K and the invoked service uses the key to decrypt the encrypted response. Database A is
replicated so that only the replicated version of the database can be accessed by Service A and other
external service consumers.
D. The Direct Authentication pattern is applied so that when Service Consumer A submits security
credentials, Service A will be able to evaluate the credentials in order to authenticate the request
message. If the request message is permitted, Service A invokes the other services and accesses
Database A. Database A is replicated so that only the replicated version of the database can be accessed
by Service A and other external service consumers.
