Important Eccouncil 312-97 Exam Questions

Answer: C

Explanation:

w3af (Web Application Attack and Audit Framework) is a Dynamic Application Security Testing (DAST) tool. It analyzes running web applications by sending crafted requests and observing responses to identify vulnerabilities such as SQL injection, cross-site scripting, and authentication flaws. Unlike SAST tools, w3af does not require access to source code and instead operates externally, simulating real-world attack behavior. SCA focuses on third-party dependencies, and IAST requires runtime instrumentation within the application. Since Debra detected vulnerabilities by actively interacting with the application, w3af clearly represents DAST. DAST tools are especially valuable during the Build and Test stage, as they validate application behavior from an attacker's perspective before deployment.

Answer: D

Explanation:

The secure communication principle focuses on protecting data as it moves between systems, services, and users. This is achieved by establishing and maintaining secure trust relationships, which include strong authentication mechanisms, encryption, certificate management, and trusted communication channels. Preventing breaches and reducing attack surface are broader security objectives, not specific to communication security. Balancing default configuration settings relates to secure defaults rather than communication. Secure trust relationships ensure that only authenticated and authorized entities can exchange data and that information remains confidential and tamper-proof during transmission. Embedding this principle into DevOps culture ensures that secure communication practices are consistently applied across all stages of the DevSecOps pipeline.

Answer: A

Explanation:

A blameless post-mortem is conducted after a security incident to analyze what happened, why it happened, and how similar incidents can be prevented in the future---without assigning individual blame. The key indicators in the scenario are that the team identified the cause, resolved the issue, and documented lessons learned for future reference. Security acceptance tests and smoke tests are pre-release validation activities, while white-box testing focuses on code-level analysis rather than incident review. Blameless post-mortems are a cornerstone of DevSecOps culture, encouraging transparency, continuous learning, and systemic improvement during the Operate and Monitor stage.

Answer: A

Explanation:

The correct installation procedure for the Sqreen PHP microagent involves downloading the installer script and executing it with the organization token and application name. The curl -s option downloads the script silently, while the > redirection operator saves it locally as sqreen-install.sh. The script is then executed using bash, passing the required token and app name as parameters. Options using input redirection (<) are incorrect because they do not save the downloaded script to a file. The -i option includes HTTP headers in the output, which is unnecessary and could corrupt the script. Installing the microagent correctly enables runtime monitoring, attack detection, and automatic blocking, supporting strong runtime security during the Operate and Monitor stage.

Answer: B

Explanation:

If a pre-commit hook script does not explicitly detect sensitive information or return a non-zero exit code, Git will treat the hook execution as successful. In this scenario, although the hook was made executable, Beth still managed to commit sensitive information. This implies that the hook either did not contain logic to detect such data or did not fail the commit upon detection. As a result, the script exited with 0, allowing the commit to proceed. Exit code 0 always signals success to Git, while non-zero exit codes block commits. This highlights the importance of properly implementing security checks within hooks, not just enabling them. Making a hook executable is necessary, but it must also include correct validation logic to enforce security policies during the Code stage.
