I fairly recently decided to create mind maps and to be honest I like them very much. Last year while preparing to Qualys Certification I created two of them and come across them today. For convenience I put them in PDF and in Mind Map format

Mind map for Vulnerability Management Module:

Mind map for Web Application Scanner Module:
QualysWAS_MindMap.pdf
