Best Validation for Successful Active Scan

B.

The correct answer is D. The scan results identify the hostname and IP address.

Explanation: Network vulnerability scanning is an important tool used by security professionals to identify vulnerabilities in a network or system. The success of a vulnerability scan can be measured by several factors, including the accuracy of the scan results, the comprehensiveness of the scan, and the ability to identify active vulnerabilities.

Option A, "The scan job is scheduled to run during off-peak hours," is not an indicator of a successful, active scan. Scheduling a scan during off-peak hours may be a best practice to minimize network impact, but it does not necessarily indicate that the scan was successful.

Option B, "The scan output lists SQL injection attack vectors," is an indicator of potential vulnerabilities, but it does not necessarily indicate a successful, active scan. The scan may have identified potential vulnerabilities, but it does not necessarily mean that those vulnerabilities are active and exploitable.

Option C, "The scan data identifies the use of privileged-user credentials," is also an indicator of potential vulnerabilities, but it does not necessarily indicate a successful, active scan. The scan may have identified potential vulnerabilities related to privileged-user credentials, but it does not necessarily mean that those vulnerabilities are active and exploitable.

Option D, "The scan results identify the hostname and IP address," is the best indicator of a successful, active scan. Identifying the hostname and IP address indicates that the scan was able to successfully detect and communicate with the target system. This information is essential for further analysis and remediation of any identified vulnerabilities.

In summary, option D is the best indicator of a successful, active scan as it confirms that the scan was able to detect and communicate with the target system.
