Final answer:
The most accurate detail during a vulnerability scan is provided by an Authenticated scan, as it has the advantage of accessing the system with proper credentials, revealing vulnerabilities that unauthenticated scans cannot detect.
Step-by-step explanation:
The method that provides the most accurate detail during a vulnerability scan is the Authenticated scan. Authenticated scans involve providing the scanner with some level of access to the system, such as login credentials. By doing so, the scanner can more thoroughly evaluate the system as it gains a deeper view similar to that of an authorized user, allowing it to detect vulnerabilities that an unauthenticated scan might miss. This method can check for vulnerabilities like misconfigurations, missing patches, and other security weaknesses that are only visible with authenticated access. The level of detail, in this case, surpasses what an attacker might see during an external scan.
In contrast, Black Box, Internal, and External view scans provide important perspectives but may have limitations. A Black Box scan is performed without any inside knowledge of the systems, mimicking an outside attacker. An Internal scan is conducted from within the organization's network, giving it visibility to threats from inside the network. Lastly, an External view scan looks at the network from the outside, identifying vulnerabilities an external attacker could exploit. However, neither of these methods gets as detailed or comprehensive a look into system vulnerabilities as an Authenticated scan would.
