Formerly working with the military, Peter responded to network attacks, and worked with both defensive and offensive red teams. Currently, Peter is a Senior Security Engineer with IBM as well as a principal instructor for the SANS Institute. People lead technology, not the other way around. Peter works daily to bring actionable intelligence out of disparate security devices for customers, making systems interoperable. Peter expounds, "Putting together networks only to tear them apart, is just plain fun, and allows students to take the information learned from books and this hands-on experience back to their particular work place."
