Final answer:
To increase the number of vulnerabilities discovered during a scan, it is essential to ensure thorough and comprehensive scanning using an advanced vulnerability scanner and appropriate configuration for deep scanning.
Step-by-step explanation:
The question pertains to methods for increasing the number of vulnerabilities discovered during a security scan. The most effective strategy to achieve this is option b) Ensure thorough and comprehensive scanning. This entails using a robust vulnerability scanner that can identify a wide range of security weaknesses across various systems and applications. It may also involve configuring the scanner with the appropriate settings to perform a deep scan, ensuring that it examines all potentially vulnerable points. A thorough scan may include penetration testing, as well as static and dynamic code analysis to uncover vulnerabilities that are not obvious on the surface. Such a comprehensive approach increases the likelihood that the scanner will detect both known vulnerabilities and previously undiscovered security issues.
Options a), c), and d) do not contribute to discovering more vulnerabilities. Instead, improving network security (a) would presumably reduce the number of vulnerabilities, while playing video games (c) and pretending vulnerabilities don't exist (d) are irrelevant activities that would neither enhance nor contribute to a security scan's effectiveness.
