On reading that the University of Notre Dame's security awareness program won an an Award of Excellence from the Special Interest Group on University and College Computing Services (SIGUCCS), I took a look at their website. I can't access the university-only security awareness materials, of course, but the public materials and the site's design demonstrate its winning ways. Striking graphics and easy navigation, clearly-written guidelines and policies, a decent range of security topics, an FAQ and more.
Well done University of Notre Dame. Nice work.
