Question 606 - CISA discussion

The greatest advantage of vulnerability scanning over penetration testing is that the testing process can be automated to cover large groups of assets. Vulnerability scanning is an automated, high-level security test that reports its findings of known vulnerabilities in systems, networks, applications, and devices. Vulnerability scanning can be performed frequently, quickly, and efficiently to scan a large number of assets and identify potential weaknesses that need to be addressed.Vulnerability scanning can also help organizations comply with security standards and regulations, such as PCI DSS1.

The other options are not as advantageous as option D, as they may not reflect the true benefits or limitations of vulnerability scanning compared to penetration testing. The testing produces a lower number of false positive results, but this is not necessarily true, as vulnerability scanning may report vulnerabilities that are not exploitable or relevant in the context of the organization. Network bandwidth is utilized more efficiently, but this may not be a significant advantage, as vulnerability scanning may still consume considerable network resources depending on the scope and frequency of the scans. Custom-developed applications can be tested more accurately, but this is also not true, as vulnerability scanning may not be able to detect complex or unknown vulnerabilities that require manual analysis or exploitation.
