We're considering turning guest access on for some of our sites, but we're concerned about security. We're a fairly large university and we have pretty sensitive data (student information, salaries, financial, advancement, medical, HR, etc).
Has anyone implemented guest access and embedded views? Have you experienced security issues? Should we shut it off completely and tell our users that we've decided not to implement it?
I'd appreciate any advice or suggestions. I'm particularly looking for real-life experiences.
