Cybersecurity survey. The information systems organization, ISACA, conducts an annual survey of cybersecurity at firms from around the world. ISACA sends survey questionnaires via email to all professionals that hold ISACA’s Certified Information Security Manager designation. Over 1,500 professionals participated in the 2015 cybersecurity survey, of which 766 responded to a question on whether or not they expect to experience a cyberattack (e.g., a Malware, hacking, or phishing attack) against their firm in the coming year. About 82% of the respondents expect to experience a cyberattack during the year (State of Cybersecurity: Implications for 2015, ISACA and RSA Conference Survey).

But how widespread is hazing, and, in fact, what constitutes hazing anyway? One study tried to get an objective handle on this persistent college phenomenon by carrying out a large survey of college and university students on 53 campuses. The study leaders defined hazing as "any activity expected of someone joining or participating in a group that humiliates, degrades, abuses, or endangers them regardless of a person's willingness to participate."

The table below shows the sample sizes for those responding and the proportions for each activity across a variety of typical campus groups.
