[winterrocks]

Add Security and/or Risk stuff to "Let’s learn the basics of open source" section

Security personnel need to know the specificities of OSS security, e.g. known vulnerabilities, CVSS, is the vulnerability exploitable in the current setup, etc.
Risk personnel on the other hand need to know for example how deprecated or unsupported components increase the risks and what kind of mitigation strategies there are. Another risk factor could be a small number of contributors, the OSS project not having good security practices, etc.

Security and/or Risk personnel roles to be added to Different roles in a company have different responsibilities for open source compliance section too.
