Question 181.<\/b><\/p>\n

A development team is adding a feature that allows users to upload configuration files. Which security control should be considered MOST important before processing the files?<\/b><\/p>\n

    \n
  1. <\/b> Increase server storage<\/span><\/li>\n
  2. <\/b> Trust files uploaded by authenticated users<\/span><\/li>\n
  3. <\/b> Validate structure, content, size, and allowed fields before use<\/span><\/li>\n
  4. <\/b> Execute the file to verify that it works<\/span><\/li>\n<\/ol>\n

    Correct Answer: 3. Validate structure, content, size, and allowed fields before use<\/b><\/p>\n

    Explanation:<\/b><\/p>\n

    Uploaded configuration files should be treated as untrusted input even when they come from authenticated users. The application should validate format, expected fields, permitted values, size limits, and any references to external resources before using the data. Processing should occur with minimal privilege, and dangerous directives should be rejected. Authentication establishes identity but does not guarantee that uploaded content is safe.<\/span><\/p>\n

    Question 182.<\/b><\/p>\n

    A secure application needs to generate password-reset tokens. Which characteristic is MOST important?<\/b><\/p>\n

      \n
    1. <\/b> The tokens are predictable so support staff can reproduce them<\/span><\/li>\n
    2. <\/b> The tokens are generated using a cryptographically secure random source<\/span><\/li>\n
    3. <\/b> The tokens never expire<\/span><\/li>\n
    4. <\/b> The tokens contain the username in plaintext<\/span><\/li>\n<\/ol>\n

      Correct Answer: 2. The tokens are generated using a cryptographically secure random source<\/b><\/p>\n

      Explanation:<\/b><\/p>\n

      Password-reset tokens must be difficult for attackers to guess. A cryptographically secure random generator provides sufficient unpredictability when used with adequate token length. Tokens should also be short-lived, single-use, securely transmitted, and invalidated after successful use. Predictable values, permanent validity, or embedded user information can make recovery mechanisms easier to exploit.<\/span><\/p>\n

      Question 183.<\/b><\/p>\n

      Which activity BEST helps identify whether a software design violates the principle of least privilege?<\/b><\/p>\n

        \n
      1. <\/b> Reviewing permissions assigned to users, services, and components against required functions<\/span><\/li>\n
      2. <\/b> Measuring network latency<\/span><\/li>\n
      3. <\/b> Reviewing user-interface colors<\/span><\/li>\n
      4. <\/b> Counting source files<\/span><\/li>\n<\/ol>\n

        Correct Answer: 1. Reviewing permissions assigned to users, services, and components against required functions<\/b><\/p>\n

        Explanation:<\/b><\/p>\n

        Least privilege requires each identity or component to receive only the permissions necessary to perform its intended function. A privilege review compares actual access with legitimate requirements and can reveal unnecessary administrative rights, broad database permissions, or excessive service access. Removing unnecessary permissions reduces the impact of credential compromise and software defects.<\/span><\/p>\n

        Question 184.<\/b><\/p>\n

        A software application cannot verify the authenticity of a configuration update received from a remote service. What is the safest response?<\/b><\/p>\n

          \n
        1. <\/b> Apply the configuration because the source is normally trusted<\/span><\/li>\n
        2. <\/b> Use the configuration temporarily<\/span><\/li>\n
        3. <\/b> Ignore the validation failure if the application is busy<\/span><\/li>\n
        4. <\/b> Reject the update until authenticity and integrity can be verified<\/span><\/li>\n<\/ol>\n

          Correct Answer: 4. Reject the update until authenticity and integrity can be verified<\/b><\/p>\n

          Explanation:<\/b><\/p>\n

          Configuration changes can significantly alter security behavior. If an application cannot verify the origin and integrity of an update, applying it may allow an attacker to change access controls, logging, or other sensitive settings. The application should reject unverified updates, log the event, and notify operators where appropriate. Secure update mechanisms should authenticate both the source and the content.<\/span><\/p>\n

          Question 185.<\/b><\/p>\n

          A software team wants to reduce exposure of sensitive data in test environments. Which approach is BEST?<\/b><\/p>\n

            \n
          1. <\/b> Use masked, synthetic, tokenized, or minimized test data whenever practical<\/span><\/li>\n
          2. <\/b> Copy the entire production database into every test environment<\/span><\/li>\n
          3. <\/b> Give all developers unrestricted access to production data<\/span><\/li>\n
          4. <\/b> Disable access controls in testing<\/span><\/li>\n<\/ol>\n

            Correct Answer: 1. Use masked, synthetic, tokenized, or minimized test data whenever practical<\/b><\/p>\n

            Explanation:<\/b><\/p>\n

            Test environments often have broader access and may not receive the same protections as production. Using synthetic, masked, tokenized, or otherwise minimized datasets can preserve testing value while reducing privacy and breach exposure. Real production data should be used only when necessary and should receive controls appropriate to its sensitivity and regulatory requirements.<\/span><\/p>\n

            Question 186.<\/b><\/p>\n

            What is the MAIN security benefit of requiring peer review for changes to authentication code?<\/b><\/p>\n

              \n
            1. <\/b> It guarantees no defects will remain<\/span><\/li>\n
            2. <\/b> It provides independent examination of security-critical logic before release<\/span><\/li>\n
            3. <\/b> It removes the need for testing<\/span><\/li>\n
            4. <\/b> It allows developers to bypass coding standards<\/span><\/li>\n<\/ol>\n

              Correct Answer: 2. It provides independent examination of security-critical logic before release<\/b><\/p>\n

              Explanation:<\/b><\/p>\n

              Authentication code is highly sensitive because mistakes can result in account takeover or complete access-control bypass. Peer review provides a second perspective that may identify logic errors, unsafe assumptions, weak token handling, or other issues missed by the original developer. Review should complement automated testing, static analysis, and security verification rather than replace them.<\/span><\/p>\n

              Question 187.<\/b><\/p>\n

              A security tester finds that a user’s account remains active after the user is deleted from the central identity system. What is the MAIN problem?<\/b><\/p>\n

                \n
              1. <\/b> Excessive password length<\/span><\/li>\n
              2. <\/b> Slow application performance<\/span><\/li>\n
              3. <\/b> Incomplete identity lifecycle and deprovisioning<\/span><\/li>\n
              4. <\/b> Weak data encryption<\/span><\/li>\n<\/ol>\n

                Correct Answer: 3. Incomplete identity lifecycle and deprovisioning<\/b><\/p>\n

                Explanation:<\/b><\/p>\n

                Account removal should propagate to dependent applications so former users do not retain access. If an application maintains an active local account after central deletion, it may create an orphaned identity. Secure lifecycle management should include provisioning, role changes, suspension, and timely deprovisioning. Centralized identity integration and periodic access reviews can help detect these gaps.<\/span><\/p>\n

                Question 188.<\/b><\/p>\n

                A release process allows a developer to both approve and deploy their own security-sensitive change. Which control is MOST appropriate?<\/b><\/p>\n

                  \n
                1. <\/b> Give the developer additional privileges<\/span><\/li>\n
                2. <\/b> Disable deployment logs<\/span><\/li>\n
                3. <\/b> Let the developer approve only emergency changes<\/span><\/li>\n
                4. <\/b> Require independent approval or separation of duties for high-risk releases<\/span><\/li>\n<\/ol>\n

                  Correct Answer: 4. Require independent approval or separation of duties for high-risk releases<\/b><\/p>\n

                  Explanation:<\/b><\/p>\n

                  Separation of duties reduces the risk that one individual can introduce and approve a harmful or unauthorized change without oversight. High-risk releases should generally require independent review or approval, with individual identities and protected logs recording each step. Emergency processes may be expedited but should still preserve accountability and post-change review.<\/span><\/p>\n

                  Question 189.<\/b><\/p>\n

                  Which software design approach BEST supports secure handling of unexpected input?<\/b><\/p>\n

                    \n
                  1. <\/b> Reject invalid input using defined validation rules and handle errors predictably<\/span><\/li>\n
                  2. <\/b> Attempt to process all malformed input<\/span><\/li>\n
                  3. <\/b> Return detailed internal diagnostics to users<\/span><\/li>\n
                  4. <\/b> Disable all input validation<\/span><\/li>\n<\/ol>\n

                    Correct Answer: 1. Reject invalid input using defined validation rules and handle errors predictably<\/b><\/p>\n

                    Explanation:<\/b><\/p>\n

                    Applications should define what valid input looks like and reject values that fall outside expected formats, ranges, or structures. Error handling should be controlled and should not reveal sensitive implementation details. Validation is most effective when combined with safe APIs, output encoding, authorization, and least privilege according to how the input is used.<\/span><\/p>\n

                    Question 190.<\/b><\/p>\n

                    A development team uses external packages from public repositories. Which practice BEST improves software-supply-chain security?<\/b><\/p>\n

                      \n
                    1. <\/b> Download the newest package available without review<\/span><\/li>\n
                    2. <\/b> Use approved repositories, verify provenance and integrity, and monitor vulnerabilities<\/span><\/li>\n
                    3. <\/b> Ignore package versions<\/span><\/li>\n
                    4. <\/b> Disable dependency inventories<\/span><\/li>\n<\/ol>\n

                      Correct Answer: 2. Use approved repositories, verify provenance and integrity, and monitor vulnerabilities<\/b><\/p>\n

                      Explanation:<\/b><\/p>\n

                      Third-party packages can introduce malicious code, compromised dependencies, or newly discovered vulnerabilities. Approved repositories, integrity verification, provenance checks, version control, and continuous vulnerability monitoring help reduce this risk. Teams should also track transitive dependencies and know which components are actually included in production builds.<\/span><\/p>\n

                      Question 191.<\/b><\/p>\n

                      A web application allows users to submit HTML content that will later be displayed to other users. Which control is MOST important?<\/b><\/p>\n

                        \n
                      1. <\/b> Increase session duration<\/span><\/li>\n
                      2. <\/b> Disable input limits<\/span><\/li>\n
                      3. <\/b> Sanitize or safely encode untrusted content according to the rendering context<\/span><\/li>\n
                      4. <\/b> Give users administrator privileges<\/span><\/li>\n<\/ol>\n

                        Correct Answer: 3. Sanitize or safely encode untrusted content according to the rendering context<\/b><\/p>\n

                        Explanation:<\/b><\/p>\n

                        User-supplied HTML can contain scripts, dangerous attributes, or active content that leads to cross-site scripting. The application should either sanitize the content using an appropriate trusted mechanism or apply context-specific output encoding when raw HTML is not required. Additional controls such as content security policies can provide defense in depth.<\/span><\/p>\n

                        Question 192.<\/b><\/p>\n

                        A software team wants to protect a critical encryption key from application administrators. Which approach is BEST?<\/b><\/p>\n

                          \n
                        1. <\/b> Store the key in a shared text file<\/span><\/li>\n
                        2. <\/b> Embed the key in application source code<\/span><\/li>\n
                        3. <\/b> Email the key to administrators<\/span><\/li>\n
                        4. <\/b> Use a dedicated key-management or hardware-backed mechanism with restricted access**<\/span><\/li>\n<\/ol>\n

                          Correct Answer: 4. Use a dedicated key-management or hardware-backed mechanism with restricted access<\/b><\/p>\n

                          Explanation:<\/b><\/p>\n

                          Highly sensitive cryptographic keys should be protected separately from ordinary application administration. Dedicated key-management services or hardware-backed mechanisms can restrict access, enforce lifecycle controls, and provide auditing. Embedding keys in code or storing them in shared files greatly increases exposure and makes rotation difficult.<\/span><\/p>\n

                          Question 193.<\/b><\/p>\n

                          Which practice BEST supports secure software retirement?<\/b><\/p>\n

                            \n
                          1. <\/b> Revoke credentials, remove integrations, address retained data, and communicate end-of-support<\/span><\/li>\n
                          2. <\/b> Leave service accounts active in case the product returns<\/span><\/li>\n
                          3. <\/b> Keep unused APIs publicly accessible<\/span><\/li>\n
                          4. <\/b> Disable monitoring before decommissioning<\/span><\/li>\n<\/ol>\n

                            Correct Answer: 1. Revoke credentials, remove integrations, address retained data, and communicate end-of-support<\/b><\/p>\n

                            Explanation:<\/b><\/p>\n

                            Retiring software securely requires more than shutting down servers. Service accounts, API keys, certificates, firewall rules, integrations, data stores, and backups should all be reviewed. Unneeded credentials and access paths should be revoked or removed, while retained data should follow legal and policy requirements. Customers and internal teams should also understand the end-of-support timeline.<\/span><\/p>\n

                            Question 194.<\/b><\/p>\n

                            A development team wants to ensure that a high-value API request has not been altered in transit. Which control BEST provides this assurance?<\/b><\/p>\n

                              \n
                            1. <\/b> Data compression<\/span><\/li>\n
                            2. <\/b> Cryptographic integrity protection such as a valid digital signature or message authentication code<\/span><\/li>\n
                            3. <\/b> Increasing API timeout values<\/span><\/li>\n
                            4. <\/b> Renaming request fields<\/span><\/li>\n<\/ol>\n

                              Correct Answer: 2. Cryptographic integrity protection such as a valid digital signature or message authentication code<\/b><\/p>\n

                              Explanation:<\/b><\/p>\n

                              Cryptographic integrity mechanisms can detect unauthorized modification of request data. Digital signatures can also provide origin authentication when keys are managed correctly, while message authentication codes provide integrity and authenticity between parties sharing a secret. The mechanism must cover all security-sensitive fields and should be combined with freshness controls when replay attacks are a concern.<\/span><\/p>\n

                              Question 195.<\/b><\/p>\n

                              A secure code review finds that an application dynamically builds SQL statements by concatenating user input. What is the BEST remediation?<\/b><\/p>\n

                                \n
                              1. <\/b> Increase database privileges<\/span><\/li>\n
                              2. <\/b> Encode the SQL statement using Base64<\/span><\/li>\n
                              3. <\/b> Replace string concatenation with parameterized queries or prepared statements<\/span><\/li>\n
                              4. <\/b> Disable database logging<\/span><\/li>\n<\/ol>\n

                                Correct Answer: 3. Replace string concatenation with parameterized queries or prepared statements<\/b><\/p>\n

                                Explanation:<\/b><\/p>\n

                                Parameterized queries separate SQL code from user-supplied data so malicious input is not interpreted as part of the command structure. This is one of the primary defenses against SQL injection. Input validation and least-privilege database accounts provide additional layers, but they should not replace safe query construction.<\/span><\/p>\n

                                Question 196.<\/b><\/p>\n

                                A product depends on an external authentication service. What should the software design define before release?<\/b><\/p>\n

                                  \n
                                1. <\/b> Only the service’s branding<\/span><\/li>\n
                                2. <\/b> The number of users supported by the product<\/span><\/li>\n
                                3. <\/b> A manual password shared by all customers<\/span><\/li>\n
                                4. <\/b> Failure behavior, timeouts, monitoring, and secure fallback or fail-secure handling**<\/span><\/li>\n<\/ol>\n

                                  Correct Answer: 4. Failure behavior, timeouts, monitoring, and secure fallback or fail-secure handling<\/b><\/p>\n

                                  Explanation:<\/b><\/p>\n

                                  External authentication creates both a security and availability dependency. The application should define what happens when the service is slow, unavailable, or returns invalid responses. Timeouts, retry behavior, monitoring, and fail-secure logic should be designed intentionally. Sensitive operations should not become accessible merely because an external dependency fails.<\/span><\/p>\n

                                  Question 197.<\/b><\/p>\n

                                  What is the MAIN purpose of maintaining a secure development metric for recurring vulnerability types?<\/b><\/p>\n

                                    \n
                                  1. <\/b> Identify patterns that can guide improvements in training, standards, and tooling<\/span><\/li>\n
                                  2. <\/b> Guarantee that all future vulnerabilities are eliminated<\/span><\/li>\n
                                  3. <\/b> Replace code review<\/span><\/li>\n
                                  4. <\/b> Reduce the number of functional tests<\/span><\/li>\n<\/ol>\n

                                    Correct Answer: 1. Identify patterns that can guide improvements in training, standards, and tooling<\/b><\/p>\n

                                    Explanation:<\/b><\/p>\n

                                    Recurring vulnerability patterns can indicate weaknesses in coding standards, developer knowledge, architecture, or automated controls. Tracking these trends helps organizations target improvements where they will have the greatest impact. Metrics should support learning and risk reduction rather than simply count defects. They are most valuable when tied to concrete improvement actions.<\/span><\/p>\n

                                    Question 198.<\/b><\/p>\n

                                    A team is designing authentication for an application that handles highly sensitive transactions. Which control is MOST appropriate for high-risk actions?<\/b><\/p>\n

                                      \n
                                    1. <\/b> Anonymous access<\/span><\/li>\n
                                    2. <\/b> Step-up authentication or additional verification before the sensitive action<\/span><\/li>\n
                                    3. <\/b> Permanent sessions with no reauthentication<\/span><\/li>\n
                                    4. <\/b> Shared user accounts<\/span><\/li>\n<\/ol>\n

                                      Correct Answer: 2. Step-up authentication or additional verification before the sensitive action<\/b><\/p>\n

                                      Explanation:<\/b><\/p>\n

                                      A user may be sufficiently authenticated for ordinary activity but require stronger assurance before performing a high-risk transaction. Step-up authentication, transaction confirmation, or additional approval can reduce the impact of stolen sessions or credentials. The strength of the additional control should reflect the sensitivity and business impact of the action.<\/span><\/p>\n

                                      Question 199.<\/b><\/p>\n

                                      A vulnerability is discovered in an unsupported software version still used by some customers. What should the organization do?<\/b><\/p>\n

                                        \n
                                      1. <\/b> Ignore the issue completely<\/span><\/li>\n
                                      2. <\/b> Remove the version from documentation and take no further action<\/span><\/li>\n
                                      3. <\/b> Follow the published support policy while communicating risk and available upgrade or mitigation options<\/span><\/li>\n
                                      4. <\/b> Restore full support automatically without evaluation<\/span><\/li>\n<\/ol>\n

                                        Correct Answer: 3. Follow the published support policy while communicating risk and available upgrade or mitigation options<\/b><\/p>\n

                                        Explanation:<\/b><\/p>\n

                                        End-of-support policies should clearly define the organization’s obligations. Even when a version is no longer supported, responsible communication may include notifying customers of risk, recommending upgrades, and providing available mitigations where appropriate. The organization should act consistently with contractual, legal, and published support commitments rather than making ad hoc decisions.<\/span><\/p>\n

                                        Question 200.<\/b><\/p>\n

                                        Which practice BEST reflects a mature CSSLP secure software program?<\/b><\/p>\n

                                          \n
                                        1. <\/b> Perform security only before initial release<\/span><\/li>\n
                                        2. <\/b> Depend on scanning tools without governance<\/span><\/li>\n
                                        3. <\/b> Leave security decisions entirely to individual developers<\/span><\/li>\n
                                        4. <\/b> Continuously integrate security requirements, design, coding, testing, release, maintenance, metrics, and improvement**<\/span><\/li>\n<\/ol>\n

                                          Correct Answer: 4. Continuously integrate security requirements, design, coding, testing, release, maintenance, metrics, and improvement<\/b><\/p>\n

                                          Explanation:<\/b><\/p>\n

                                          A mature secure software program integrates security throughout the full lifecycle. Requirements define objectives, architecture manages systemic risk, coding practices reduce implementation defects, testing provides evidence, controlled release protects production, and maintenance addresses new vulnerabilities. Metrics and lessons learned should feed continuous improvement. Governance ensures these activities are repeatable, accountable, and aligned with business risk.<\/span><\/p>\n
