The field of cybersecurity has evolved far past its original roots as a discipline focused exclusively on protecting computer systems.

The work at Purdue University’s Center for Education and Research in Information Assurance and Security (CERIAS) is a true example of the scale and breadth of security research in 2020, says managing director Joel Rasmus.
