Question
Which of the following is the primary purpose of implementing “defense in depth” as a security concept in an organization?
A. To manage incidents through multiple nodes of escalation
B. To create multiple layers of security controls to prevent unauthorized access
C. To ensure compliance with privacy regulations through strong security measures
D. To monitor and detect security incidents in real-time to minimize privacy breaches
Answer
B. To create multiple layers of security controls to prevent unauthorized access
Explanation
The primary purpose of implementing “defense in depth” as a security concept in an organization is to create multiple layers of security controls to prevent unauthorized access (B).
Defense in depth is a cybersecurity approach that employs a series of layered security controls to protect an organization’s assets, systems, and data. By implementing multiple security measures at different levels, the organization can create a robust and comprehensive security posture that is more difficult for attackers to penetrate.
The key aspects of defense in depth include:
- Layered security: Implementing various security controls at different levels, such as network perimeter defenses, access controls, encryption, and endpoint protection.
- Redundancy: Ensuring that if one layer of security fails, other layers can still provide protection.
- Comprehensive coverage: Addressing security risks across all aspects of the organization, including physical, technical, and administrative controls.
While defense in depth can help manage incidents through multiple nodes of escalation (A), ensure compliance with privacy regulations (C), and facilitate real-time monitoring and detection of security incidents (D), its primary purpose remains the prevention of unauthorized access through the creation of multiple layers of security controls.
By adopting a defense in depth approach, organizations can significantly reduce the risk of data breaches, protect sensitive information, and maintain the confidentiality, integrity, and availability of their systems and data.
