Visitors should not see other Lists and Libraries

Rahul14Think about you problem in comparison to a house. Now when you have give access to someone you have given access to the house and now they can access all the rooms which are open to them. If you want them to access only a single room which you have given access to them then you have to lock other rooms as well.

So now coming out of analogy you have to set the permission in a way where all the other list and libraries are restricted for the user (remove permission for the user) and only allow the user where he needs. But be careful there are some lists like Style Library ans Site assets you should have the user access otherwise use might not get in.
