We are pleased to post the first in a series of articles by Michael J. Skroch of Sandia Labs on the modeling and simulation of red teaming. Michael is a founding member of the red teaming community and is well known within the community as a proponent of better red teaming methods and practices. He has written this article specifically for Red Team Journal and its readers. We believe the article is likely to become a standard reference in the field. You may download it as a PDF here.
