FB Security of FB Members

What sort of measures are in place in the very unlikely event (let’s hope) FB got hacked? How is everyone in the FB Family protected regarding their personal data, credit cards, etc? I had an incident with one of my work clients today and it got me thinking about my personal data with FB and many other internet venues.

I’m sure FB is on top of it, but it’s a necessary question in these uncertain times.

Thank You!
