If you enter anything into the Require password field, the student must enter that password to access the quiz.

With Require network address, you can restrict access to the quiz to particular IP address/addresses. For example, you can restrict the quiz's access to the following
IP addresses:

• 146.203.59.235: This is a single IP address. It will permit a single computer to access the quiz. If this computer is acting as a proxy server, the other computers behind it can also access the quiz.
• 146.203: This is a range of IP addresses. It will permit any IP address starting with those numbers. If those numbers belong to your company, you effectively limit access to the quiz to your company's campus.
• 146.203.59.235/20: This is a subnet. It will permit the computers on that subnet to access the quiz.

The Enforced delay settings prevent students from attempting the quiz without waiting between attempts. If you show the students the correct answers after they submit the quiz, you might want to set a delay between attempts. This prevents students from attempting the quiz, seeing the correct answers, and then immediately trying the quiz again while those answers are fresh in their memory.

If Browser security is set to Full-screen popup..., it launches the quiz in a new browser window. It uses JavaScript to disable copying, saving, and printing. This security is not foolproof.
