Which tool is commonly used to scan systems for software vulnerabilities?

• A. Nessus
• B. Tripwire
• C. Wazuh
• D. Zeek

Answer: (A)

Vulnerability scanning involves automatically checking systems for known weaknesses by comparing installed software versions and configurations against a database of published vulnerabilities. Nessus is the tool commonly used for this purpose. It scans hosts and services with a comprehensive set of plugins to detect missing patches, misconfigurations, default credentials, and other risk factors tied to known CVEs. It can perform both traditional network-based checks and credentialed scans to dive deeper, then produce actionable reports with severity and remediation guidance. The other tools focus on different security tasks: Tripwire monitors file integrity and changes to critical files; Wazuh handles log analysis and SIEM-style detection; Zeek analyzes network traffic for anomalies. So for identifying software vulnerabilities across systems, Nessus is the best-fit choice.
