Bob is having no luck performing a penetration test on Retail Store's network. He is running the test from home and has downloaded every security scanner that he could lay his hands on. Despite knowing the IP range of all the systems, and the exact network configuration, Bob is unable to get any useful results. Why is Bob having these problems?

Incomplete question. The full question read;

Why is Jim having these problems?

Options:

A. Security scanners are not designed to do testing through a firewall.

B. Security scanners cannot perform vulnerability linkage.

C. Security scanners are only as smart as their database and cannot find unpublished vulnerabilities.

D. All of the above.

D. All of the above.

Explanation:

Remember, security scanners are only designed to gather information about a network, but not with the ability to perform firewall testing. Also, these security scanners are pre-programmed with existing vulnerabilities in their database, and so it would impossible to discover vulnerabilities on the Retail store's network.

Hence, since Bob is using the wrong tools, he is unsuccessful in performing a penetration test.
