1.
An organization is developing a mission-critical enterprise system that
must satisfy security, availability, privacy, and regulatory requirements.
During the initial engineering phase, the security architect wants to
ensure that security requirements are derived before selecting
technologies or designing individual components. Which approach
BEST supports this objective?
A. Select security products first and derive requirements from their
capabilities
B. Identify stakeholders, mission/business objectives, risks, constraints,
and security needs before architectural design
C. Deploy compensating controls after the system enters production
D. Perform penetration testing before defining security requirements
Answer: B. Identify stakeholders, mission/business objectives, risks,
constraints, and security needs before architectural design
Rationale: Systems security engineering begins by understanding
mission/business needs, stakeholders, risks, constraints, and security
requirements. Security should be engineered into the system from the
beginning rather than retrofitted through products or post-deployment
testing.

,A systems security engineer is asked to establish traceability between
organizational objectives, security requirements, architectural decisions,
implementation components, verification activities, and operational
controls. Which engineering artifact is MOST appropriate?
A. Security awareness matrix
B. Requirements traceability matrix
C. Incident response playbook
D. Vulnerability disclosure policy
Answer: B. Requirements traceability matrix
Rationale: A requirements traceability matrix establishes relationships
between requirements and downstream design, implementation,
verification, and validation activities. This allows engineers to
demonstrate that requirements have been addressed and tested
throughout the system life cycle.


3.
An engineering team is designing a distributed financial application. A
critical security requirement states that unauthorized modification of
transaction records must be prevented and detected. Which combination
BEST addresses this requirement?
A. Encryption of network traffic only
B. Access control, integrity mechanisms, audit logging, and independent
monitoring
C. Increased network bandwidth
D. User interface validation only
Answer: B. Access control, integrity mechanisms, audit logging, and
independent monitoring
Rationale: Protecting transaction integrity requires multiple
complementary mechanisms. Access controls prevent unauthorized
2

,actions, integrity controls detect or prevent modification, logging
provides accountability, and independent monitoring can identify
anomalous activity.


4.
During system development, an engineer discovers that a proposed
architecture satisfies functional requirements but creates a significant
security dependency on a single authentication service. Failure of that
service would prevent all users from accessing critical operations. What
security engineering concern does this MOST directly represent?
A. Excessive usability
B. Common-mode or single-point-of-failure risk
C. Excessive data normalization
D. Overclassification of information
Answer: B. Common-mode or single-point-of-failure risk
Rationale: A security architecture that depends on a single critical
component can create a common-mode failure or single point of
failure. Resilience engineering should identify and mitigate such
dependencies through redundancy, fault tolerance, graceful
degradation, or alternative mechanisms.


5.
A system security engineer needs to determine whether security controls
will continue operating correctly after software updates, hardware
replacements, configuration changes, and environmental modifications.
Which engineering activity is MOST important?
A. Continuous configuration and change management
B. Annual employee satisfaction surveys

3

, C. Marketing analysis
D. Procurement forecasting
Answer: A. Continuous configuration and change management
Rationale: Security properties can be weakened by changes that were
not present during the original design. Configuration and change
management provide mechanisms for evaluating, approving,
documenting, and verifying changes so that security requirements
remain satisfied.


6.
An organization wants to reduce the consequences of a compromised
workstation. The architecture team proposes dividing the network into
security zones and restricting communication between zones according
to business requirements. Which principle is being applied?
A. Least functionality
B. Defense in depth and segmentation
C. Complete mediation avoidance
D. Open design
Answer: B. Defense in depth and segmentation
Rationale: Network segmentation limits attack propagation and
reduces the blast radius of compromise. When combined with multiple
security mechanisms, segmentation contributes to defense in depth
and containment.


7.
A system contains highly sensitive information. The engineering team
decides that every request to access protected information must be
evaluated against authorization rules, even if the requester previously
