whitelist do i need with sly uk for just a few friends in group

hi all
do i need to protect my sly uk sd only card with a whitelist if i only have a few family members connected,i am using oscam with mgcamd for my friends
thanks Baz

thanks for the reply m8, is it best to have 1 though to stop killer emus or can that only happen if you do not know all of your peers?
as i said its just a handfull of family/friends connecting and i set up their boxes with mgcamd 138
