Which tool detects vulnerabilities on networks?

• A. Nessus
• B. L0phtcrack
• C. WinDbg
• D. CapME

Answer: (A)

Detecting vulnerabilities on networks is done with an automated vulnerability scanner that probes hosts and services to find known weaknesses, missing patches, and misconfigurations. Nessus performs this role by scanning ranges of devices, analyzing operating systems, applications, and network services, and cross-referencing findings with databases of known vulnerabilities (like CVEs). It then generates reports that guide remediation, making it the tool designed specifically for identifying weaknesses across a network. L0phtcrack, by contrast, is focused on password security—auditing and cracking password hashes to assess credential strength rather than scanning for network vulnerabilities. WinDbg is a Windows debugger used for analyzing software behavior and debugging, not for vulnerability discovery across networks. CapME isn’t a network vulnerability scanner either; it serves other security tasks outside detecting network weaknesses. So Nessus is the tool that detects vulnerabilities on networks.
