1: DEFENSIBLE SECURITY ARCHITECTURE FUNDAMENTALS
QUESTION 1
Which of the following best defines "Defensible Security Architecture"?
A) A security model that focuses solely on perimeter defenses
B) A framework that assumes breaches will occur and focuses on detection and
response
C) An architecture that relies entirely on signature-based detection
D) A model that eliminates all vulnerabilities before deployment
E) A system that focuses exclusively on endpoint protection
☑ CORRECT ANSWER: B) A framework that assumes breaches will occur and
focuses
on detection and response
RATIONALE: Defensible Security Architecture acknowledges that no system is
perfectly secure and that breaches are inevitable. It emphasizes building
systems that can detect intrusions, respond effectively, and minimize damage —

,rather than assuming a perfect perimeter can prevent all attacks.
QUESTION 2
Which principle is foundational to the concept of "defense in depth"?
A) Single layer of security is sufficient if properly configured
B) Multiple overlapping layers of security controls provide resilience
C) Perimeter security is the most critical layer
D) Security controls should be minimized for performance
E) Only network-level controls are necessary
☑ CORRECT ANSWER: B) Multiple overlapping layers of security controls provide
resilience
RATIONALE: Defense in depth is based on the principle that a single security
control is insufficient. By implementing multiple, overlapping layers of
security (physical, network, host, application, data), the failure of one layer
does not compromise the entire system.
QUESTION 3
What is the primary goal of a "security architecture" in an organization?
A) To implement every available security technology
B) To align security controls with business objectives and risk tolerance
C) To eliminate all security risks
D) To focus exclusively on compliance requirements
E) To reduce IT infrastructure costs
☑ CORRECT ANSWER: B) To align security controls with business objectives and
risk tolerance

,RATIONALE: Security architecture is about strategically designing security
controls that support business goals while managing risk to an acceptable level.
It is not about implementing every technology or eliminating all risks, but
about informed, risk-based decision-making.
QUESTION 4
Which of the following is a key characteristic of a "defensible" architecture?
A) It prevents all attacks from succeeding
B) It provides visibility into security events and enables rapid response
C) It eliminates the need for security monitoring
D) It relies exclusively on perimeter firewalls
E) It requires no incident response planning
☑ CORRECT ANSWER: B) It provides visibility into security events and enables
rapid response
RATIONALE: A defensible architecture provides comprehensive visibility into
security events through logging, monitoring, and alerting. This visibility
enables rapid detection and response to security incidents, which is essential
when attacks inevitably occur.
QUESTION 5
Which framework is most commonly used as a reference for security architecture
design?
A) ITIL
B) TOGAF
C) ISO 27001
3|Page
, D) NIST Cybersecurity Framework (CSF)
E) COBIT
☑ CORRECT ANSWER: D) NIST Cybersecurity Framework (CSF)
RATIONALE: The NIST Cybersecurity Framework provides a comprehensive set of
guidelines for improving security posture through five core functions: Identify,
Protect, Detect, Respond, and Recover. It is widely adopted as a reference for
security architecture design.
QUESTION 6
What does the principle of "least privilege" require in security architecture?
A) All users should have administrative access
B) Users and systems should have only the minimum access necessary
C) Access should be granted based on seniority
D) All systems should have open access by default
E) Access controls should be applied only to sensitive data
☑ CORRECT ANSWER: B) Users and systems should have only the minimum access
necessary
RATIONALE: Least privilege requires that users, applications, and systems are
granted only the minimum access required to perform their functions. This limits
the potential damage from compromised accounts or systems.
QUESTION 7
Which security control is an example of a "preventive" control?
A) Intrusion Detection System (IDS)
