Free ISSAP Security Design Principles Questions and Answers

Question 1

Which of the following is the primary goal of security design principles?

Accepted Answer

To reduce vulnerabilities and mitigate risks

Answer

The primary goal of security design principles is to build systems that are inherently resilient against attacks. By incorporating these principles, architects aim to minimize potential weaknesses (vulnerabilities) and reduce the likelihood and impact of security incidents (risks).

Question 2

What is the principle of "least privilege" in security design?

Accepted Answer

Limiting access rights to the minimum necessary for a role

Answer

The principle of "least privilege" dictates that users, programs, or processes should only be granted the absolute minimum permissions required to perform their legitimate functions. This minimizes the potential damage if an account is compromised, as an attacker would have limited access.

Question 3

Which security design principle involves dividing a system into smaller parts to reduce overall risk?

Accepted Answer

Separation of duties

Answer

Separation of duties is a security design principle that involves dividing critical tasks among multiple individuals or components to prevent any single person or entity from having complete control. This reduces the risk of fraud, error, or malicious activity by requiring collusion to compromise the system.

Question 4

The concept of "defense in depth" relies on which of the following?

Accepted Answer

Multiple redundant layers of security controls

Answer

"Defense in depth" is a cybersecurity strategy that employs a series of overlapping and redundant security controls to protect information and systems. If one layer of defense fails, subsequent layers are in place to detect and prevent an attack, providing a more robust security posture.

Question 5

What does the principle of "fail-safe defaults" emphasize?

Accepted Answer

Systems should fail in a secure state, restricting access

Answer

The principle of "fail-safe defaults" ensures that when a system component fails or an error occurs, it defaults to a secure, restrictive state rather than an open or permissive one. This prevents unauthorized access or data exposure during system malfunctions, maintaining security.
