A data breach isn’t always the work of a high-tech malware hack. Sometimes it can stem from unintentional or malicious act of an employee, especially if that employee believes corporate data belongs to them.

It’s not a far-fetched scenario, according to “Insider Data Breach,” a survey of 4,000 U.S.- and U.K.-based employees commissioned by Egress Software Technologies and conducted by Opinion Matters. The survey found that 29 percent of respondents believed they owned company data.
