Answer 1

I would say that, since the OP has so little info, there are no policies in use.  It there were then this question would never be asked the way it is being asked.
I had a client call with a letter from their insurance company; an accountant with malpractice insurance.  THey asked the same question inmuch the same way.  "What computer can you users access?"  The question should be more like
"Do you have a policy that restricts access to computers and do you audit for compliance?"
I have had other clients whose insurance asked the question in that way.  It produces a better view of what should be happening and how to show compliance.
I recommend that companies being asked these questions by their legal departments or insurance companies should contract with a god computer security consultant to assist with answering these very tricky questions.  Of course if it is just you boss's
curiosity  then you may need to discuss his requirements with him in more depth.
¯\_(ツ)_/¯
