Question 1 of 66

The software security group is conducting a maturity assessment using the Building Security in Maturity Model (BSIMM). They are currently focused on reviewing attack models created during recently completed initiatives.

Which BSIMM domain is being assessed?

Answer choices
Show answer

Correct answer: C

Intelligence is the BSIMM domain that includes developing and using attack models to understand likely threats, attacker goals, and system weaknesses. These models provide security guidance that can be applied during design and throughout development initiatives. Governance addresses program oversight and policy, while SSDL touchpoints focuses on integrating security activities into the development process.

Question 2 of 66

Using a web-based common vulnerability scoring system (CVSS) calculator, a security response team member performed an assessment on a reported vulnerability in the user authentication component of the company’s new product. The basso score of the vulnerability was 8.3 and changed to 9.4 after adjusting temporal and environmental metrics.

Which rating would CVSS assign this vulnerability?

Answer choices
Show answer

Correct answer: B

A CVSS score of 9.4 falls within the Critical severity range, which covers scores from 9.0 to 10.0. The temporal and environmental metrics refine the initial base score to reflect current exploit conditions and the affected organization’s environment. Although the original 8.3 base score is High, the adjusted score raises the vulnerability into the Critical category.

Question 3 of 66

An individual is developing a software application that has a back-end database and is concerned that a malicious user may run the following SQL query to pull information about all accounts from the database:

SELECT * FROM accounts WHERE accountID=’ “ ‘ or ‘1’=’1’;

Which technique should be used to detect this vulnerability without running the source codes?

Answer choices
Show answer

Correct answer: C

Static analysis examines application source code or compiled artifacts without executing the program. It can identify unsafe SQL query construction, such as concatenating user input into a query, which permits SQL injection conditions like an always-true OR clause. Dynamic analysis and fuzz testing require the application to run, while cross-site scripting is a different web vulnerability rather than a detection technique.

Question 4 of 66

Company leadership has contracted with a security firm to evaluate the vulnerability of all externally facing enterprise applications via automated and manual system interactions.

Which security testing technique is being used?

Answer choices
Show answer

Correct answer: C

Penetration testing evaluates the security of externally accessible applications by simulating attacker behavior through automated tools and manual interaction. It identifies exploitable vulnerabilities in deployed systems, such as weak authentication, exposed services, and insecure configurations. Source-code analysis examines application code rather than interacting with the running external application, while fault injection deliberately introduces errors to observe system behavior.

Question 5 of 66

Which secure coding practice involves clearing all local storage as soon as a user logs off for the night and will automatically log a user out after an hour of inactivity?

Answer choices
Show answer

Correct answer: D

Session management controls the lifecycle of an authenticated user's session, including how long it remains valid and what data persists after logout. Clearing local storage on logout helps prevent session tokens or sensitive data from being reused by another person on the same device. Automatically ending a session after an hour of inactivity reduces the risk of unauthorized access from unattended devices. Access control determines permissions, but does not primarily govern timeout and logout behavior.

Stories from the certified

Charles Sirois
Canada
As this was my first certification exam, I was understandably nervous about what to expect. These study materials made the preparation process much easier, and many of the questions closely reflected those on the actual exam.
Lance Chambers
United States
Wasted about a month going through the free dump sites scattered all over reddit, half the answers were wrong and the other half were for a version of the exam that doesn't even exist anymore. Eventually gave in and paid the small fee here, and the difference was night and day.
Alisha Kelly
Italy
Honestly, I had already gone through the official documentation quite thoroughly, but still didn't feel fully confident going in. This helped things finally click for me. I realized I knew the material, but just hadn't connected all the pieces yet.
Casper Claassen
Netherlands
Used this along with Microsoft Learn and the combo worked really well. The practice questions made the stuff I'd read actually stick. Passed first attempt, no complaints from me.
Gabriele Ghesla
Italy
The content is accurate and clearly presented, and it's more affordable than competitors. The team has been incredibly responsive whenever I've had an issue, and they've been open to small changes that improve the platform.

I don't usually leave reviews, but this one felt worth sharing. The questions were quite close to what actually appeared on the exam, more than I expected. I spent about a week going through the material before my test, and it helped me feel more prepared.
Remi Nuyts

Passed ITIL 4 Foundation with 87%. Material was enough by itself.
