Mike Halsall is Senior Network and Information Security Analyst at MIT, and currently sits on a number of steering committees for various Information Sharing and Analysis Centers. He has 18 years working in both corporate and academic environments, having held positions at IBM, AT&T, Bell Atlantic, Vermont Technical College and Middlebury College. As a fellow for The Center, he will be exploring various frameworks for making ethical decisions in the domain of computer security.
