Which vulnerability scanner is derived from SATAN and is considered the original vulnerability scanner?

• A. Nessus
• B. Saint
• C. OpenVAS
• D. Qualys

Answer: (B)

The idea being tested is the historical lineage of early vulnerability scanners and which one directly traces back to SATAN. Saint is the correct pick because it was developed as a direct descendant of SATAN, built to extend and refine the same concept of network vulnerability analysis that SATAN introduced. It’s widely recognized as the original vulnerability scanner in the SATAN lineage.

Nessus came after as a prominent scanner but did not originate from the SATAN codebase in the same direct way Saint did. OpenVAS grew from Nessus rather than from SATAN, and Qualys is a commercial product with a separate development path.
