GDPR again!!

Hello,

I have now done online training about GDPR.
I would like to update some policies .

How do you call the policy: GDPR policy ?
data protection policy?
data protection and confidentiality policy ?
confidentiality and privacy policy?
Do you also mention GDPR in safeguarding policy ?

Also I still don't understand what is a DATA AUDIT? what do we need to do about it ( another policy?)
These questions have probably already been answered somewhere but cant find anything .
thanks
