Barry Schrager


Barry Schrager, who has a M.S. in applied mathematics from Northwestern University, is a seminal figure in the design and development of early computer security software products. From 1968 to 1978 he served as assistant director of the University of Illinois-Chicago Computer Center, where activity of student hackers on the center's time-shared system led him to investigate methods and tools to achieve greater security. In the early 1970s he became involved with IBM SHARE, and led a committee of emerging computer security experts--SHARE's Data Security and Management Group (see e-book below). Schrager and his group's 1974 SHARE white paper defined access control requirements to achieve security, which led to IBM's 1976 computer security software product, Resource Access Control Facility (RACF). Initially this product fell short of the requirements outlined in the white paper and Schrager and a colleague at the University of Illinois--Chicago Computer Center, Eberhard Klemens, developed Access Control Facility (ACF). In 1978, these two teamed up with Scott Krueger to found SKK Corporation and refine this computer security software product as ACF2. Its first customer was London Life Insurance (Ontario, Canada).(1) Soon thereafter SKK sold this product to General Motors and many other major corporations/organizations.(2) Subsequently, ACF2 captured approximately 60 percent of the U.S. market for access control software products, proving to be a more robust product than IBM's own RACF. Over time, ACF2 in its different versions has generated more than $1 billion in revenue (it is now owned and maintained by Computer Associates).(3)(4)
