Vulnerability Management - Is vulnerability really fixed ?

You might be providing vulnerability scan reports to platform teams on adhoc basis. Just be careful while sending scan based reports. Why ? .. Because sometimes scanner is able to detect host(s) as live but due to firewall blocking the traffic, it is not able to gather any information. Hence, you will find only few QID/Plugin ID(s) in scan based report but this does not mean that all other vulnerabilities are fixed. 


If you are fetching scan based report for a single host you will be able to easily observe that quickly (firewall hindering network traffic) but for multiple systems, it becomes difficult to spot without proper analysis.


Hence, best is to use host based report but if in case of urgency, you can use scan based report.


You can refer my blog https://tejas1to4.blogspot.com/2022/10/vulnerability-management-scan-vs-host.html for differences between scan and host based findings.  

Bottom-line is, if you do not find a particular vulnerability in a scan based report, first ensure whether the scan happened properly or not before reaching to any conclusion regarding the vulnerability (don't assume the vulnerability got fixed because you are not seeing it in the scan based report).


Happy Learning !!
