What can universities do to stop students cheating?

Cheating among students has reached unprecedented levels worldwide from academic misconduct among Britain's Russell Group universities from 2014 to 2017; ongoing cheating among student-athletes to enter or to stay at universities in the United States; unauthorized exam assignment sharing in Switzerland; contract cheating in Australia to plagiarism in many Eastern European countries. If universities just declare their integrity but do not practice it, they might not be able to expect it from students.
