It's a dangerous world out there, with IT shops hard pressed to protect their institutions and users. "Campus Technology" looks at the 4 biggest security worries--and how IT can fight back. In 2012, 61 educational institutions reported data breaches, involving more than 2 million records, according to the nonprofit Identity Theft Resource Center. When speaking to university IT professionals, one resounding message about security is heard: The battle never ends. Schools are in a constant arms race to stay ahead of hackers who have become increasingly sophisticated in their efforts to breach the battlements of university networks, where vast amounts of personal and financial data are stored. The challenge facing schools is to find ways to foil these attacks without resorting to the kind of total lockdown that makes it impossible for universities to conduct research, innovate, and collaborate freely. As Jesse Davis, director of research and development at DataDirect, points out, the original internet protocols were meant to share information, not restrict it.
