?What is Nessus Vulnerability Scanner, and how does it work

Nessus is a widely-used vulnerability scanner that helps identify security flaws in networks, systems, and applications. It works by performing scans on systems, checking for known vulnerabilities, misconfigurations, and potential weaknesses. Nessus uses a database of plugins to detect these vulnerabilities and provides detailed reports, which help security professionals mitigate risks.

?How do you interpret the results from a Nessus vulnerability scan

Nessus scan results categorize vulnerabilities based on severity levels (critical, high, medium, and low) and provide detailed descriptions. To interpret the results, focus on critical and high-severity vulnerabilities first, assess their potential impact, and prioritize remediation efforts. Nessus also offers recommendations for patching and securing systems based on the identified vulnerabilities.
