I recently conquered the WGU Secure Software Design (D487, KEO1) exam and edged through with the help of Pass4Success practice questions, which gave me the confidence I needed when facing tricky items. One question that stuck with me asked about secure design patterns focusing on threat modeling and risk mitigation, specifically how to apply least privilege and defense in depth within a modular architecture; I was unsure whether the correct approach combined identity-based access control with component-level isolation, yet I still managed to pass after reviewing the related topic on secure design principles. "Can you explain how to map attacker goals to attack surfaces using STRIDE and how that informs your defense strategies?" was the exam prompt I dreaded, but the practice questions helped me narrow down the best defense, though I felt uncertain about which STRIDE category aligned with certain subtle data flow weaknesses.

Question #2

What is a countermeasure to the web application security frame (ASF) data validation/parameter validation threat category?

Reveal Solution Hide Solution
Correct Answer: A

Question #3

What is an advantage of using the Agile development methodology?

Reveal Solution Hide Solution
Correct Answer: A

Question #4

Recent vulnerability scans discovered that the organization's production web servers were responding to ping requests with server type, version, and operating system, which hackers could leverage to plan attacks.

How should the organization remediate this vulnerability?

Reveal Solution Hide Solution
Correct Answer: A

To remediate the vulnerability of servers responding to ping requests with sensitive information, the organization should configure the servers to return as little information as possible to network requests. This practice is known as reducing the attack surface. By limiting the amount of information disclosed, potential attackers have less data to use when attempting to exploit vulnerabilities. Regular updates and patching (Option B) are also important, but they do not address the specific issue of information disclosure. Uninstalling or disabling unnecessary features (Option C) and restricting access to configuration files (Option D) are good security practices, but they do not directly prevent the leakage of server information through ping responses.


Question #5

Which secure software design principle assumes attackers have the source code and specifications of the product?
