Layer your defenses and your assessments! - -Vulnerability Assessment Specialist: Remember: vulnerability scanners are reconnaissance tools. Use them only on authorized targets. - -+ [Any final advice?] - Vulnerability Assessment Specialist: Be systematic. Run all the tools, document findings, and compare results. - - Vulnerability Assessment Specialist: Pay attention to what each tool finds that others miss - this teaches you their strengths and weaknesses. - - Vulnerability Assessment Specialist: Don't just collect scan results - verify critical findings by actually exploiting them. - - Vulnerability Assessment Specialist: The limitations of these tools are as important as their capabilities. Real attackers won't stop at what scanners find. - - Vulnerability Assessment Specialist: Take notes on severity ratings, CVE numbers, and remediation advice - these make great report content. - - Vulnerability Assessment Specialist: Good luck, Agent {player_name}.
