Which of the following is a program that can be used to probe a host for vulnerabilities ?
C
Correct answer
Explanation
SATAN (Security Administrator Tool for Analyzing Networks) is a well-known vulnerability scanning tool that probes hosts for security weaknesses. It systematically checks for known vulnerabilities, misconfigurations, and potential security issues across network services. Trojans are malicious programs hiding within legitimate software, demons are background processes in Unix, and Unix is an operating system - none of which are vulnerability scanners. Note: SATAN was developed in the 1990s and modern equivalents include Nessus or OpenVAS.
