Was handed a project to get the QA team involved with security testing

I am a manager of a couple teams one of which is QA, however the vast majority of my own technical background is in backend development work. Still getting up-to-speed on QA itself to this day but largely started to reach comfort with that team.

But yesterday at the last second I was given the task of creating a proposal for getting QA involved with security testing in 2 days. Primary goal is regular vulnerability scanning I assume to keep security responsible since someone will at least lightly be checking their work.

So my main question would be if anyone here has any experience or resources they'd be willing to share with getting involved in security testing from a QA perspective. Pretty much all suggestions are welcome and appreciated.
