We have been under a hack attempt, like 60 in the last 48 hours. Is there a way to stop it and find out who it is?

Hi, looking for answers. I am running windows 7 and Norton 360 and we have been under hack attempts, like 60 in the last 48 hours. Some seconds after each other. Seems to be trying to get though Norton as they are the most listed. Norton has stopped them but is there a way to find out who it is and stop it completely? Thank you everyone for your help. A Rice
