A software development team is adopting secure coding practices. They decide to implement input validation for all user-supplied data. Which approach is recommended as the most effective for preventing injection attacks?

An organization is migrating to a new application that uses serialized objects to transfer data between services. The security team is concerned about insecure deserialization attacks. Which of the following controls is most effective in preventing deserialization vulnerabilities?

A web application exposes an API that allows users to fetch data from internal network resources based on a URL parameter. An attacker discovers they can use this API to access internal servers that are not meant to be public. Which vulnerability is being exploited?

A security analyst is reviewing the error handling of an application. The application currently displays detailed stack traces to users when an exception occurs. Which of the following is the best practice for error handling in production?

A security engineer is evaluating a web application for common vulnerabilities. The application uses a Content Management System (CMS) that is outdated and has known vulnerabilities. Additionally, the application displays detailed error messages and uses default administrative credentials. Which TWO of the following OWASP Top 10 categories are most relevant to these issues?

During a security audit of a web application, the following issues are found: (1) Session tokens are included in URLs, (2) The application does not invalidate session tokens after logout, and (3) Session tokens are predictable. Which THREE of the following controls are most appropriate to address these issues?

A security team is planning to integrate security testing into the software development lifecycle. They want to identify vulnerabilities early and often. Which TWO of the following testing methods should be implemented during the development phase (before deployment) to catch code-level vulnerabilities?

During the requirements gathering phase of a software development project, which threat modeling methodology is most commonly used to identify threats such as spoofing, tampering, and elevation of privilege?

A development team is implementing a web application that allows users to search for products. To prevent SQL injection attacks, which secure coding practice should be applied?

A security architect is reviewing a design for an e-commerce application. The architect recommends implementing defense in depth. Which of the following is an example of this principle?

Which type of security testing involves analyzing source code for vulnerabilities without executing the code?

A company is evaluating a third-party software library for use in their application. Which document provides a detailed inventory of the library's components and dependencies to help assess supply chain risk?

During a security review of a web application, testers discover that the application discloses detailed error messages to users, including stack traces. Which secure coding best practice is being violated?

An application authenticates users using session tokens. A security analyst finds that the application does not invalidate session tokens after logout, allowing session fixation attacks. Which secure coding practice should be implemented to mitigate this?

A developer is implementing cryptographic storage for sensitive user data. Which of the following is a cryptographic best practice?

Which of the following is an example of an Insecure Direct Object Reference (IDOR) vulnerability?

A security team is conducting a penetration test on a web application. They identify that the application is vulnerable to reflected cross-site scripting (XSS). Which of the following is the most effective mitigation?

During a vulnerability assessment, a security analyst discovers that a web application uses a library known to be vulnerable to Log4Shell (CVE-2021-44228). Which type of vulnerability does this represent?

A development team is designing a new application and wants to ensure that if a failure occurs, the system remains secure by default. Which design principle should they apply?

A security analyst is reviewing a web application that handles financial transactions. Which TWO of the following are effective controls against Cross-Site Request Forgery (CSRF)?

An organization is acquiring a third-party software product. Which THREE of the following should be included in the security assessment of the vendor?

During the requirements gathering phase of a secure SDLC, the team uses a threat modeling approach that focuses on identifying threats such as spoofing, tampering, and denial of service. Which threat modeling methodology is being employed?

A security architect is designing an authentication system. To prevent session fixation attacks, which secure design principle should be implemented?

Which of the following is the primary purpose of output encoding in web application security?

During a security assessment, a penetration tester discovers that a web application exposes internal IP addresses in error messages. Which vulnerability category does this represent?

A development team is using a third-party library that is known to have a critical vulnerability. The team decides to continue using the library because it is widely used and the vulnerability has not been exploited. Which security risk is the team ignoring?

Which of the following is a secure coding practice to prevent SQL injection attacks?

A security analyst is reviewing a web application and notices that it includes a feature that allows users to view their own profile by providing a user ID in the URL (e.g., /profile?userid=123). The application does not verify that the logged-in user owns that profile. Which vulnerability is present?

Which type of testing analyzes source code for security vulnerabilities without executing the program?
