About the Authors

Joseph Steinberg has been involved with computer networking and security since 1989. He has worked in technical positions at Citibank and AT&T and served in senior-management capacities at several product vendors and consulting firms. He has spent more than four years with Whale Communications, one of the pioneers of SSL VPN technology.

Mr. Steinberg’s May 2003 article, SSL VPN Security, introduced an awareness of critical security issues created by SSL VPN technology; since its publication, nearly every SSL VPN vendor has acted upon the concerns and recommendations made in the article.

Mr. Steinberg earned an M.S. in Computer Science from NYU, and holds a CISSP (Certified Information Systems Security Professional) credential as well as advanced certifications in IT security management (ISSMP) and architecture (ISSAP). He has lectured on several topics related to IT security and management and has authored numerous articles that have appeared in various journals, magazines, and other publications. A recognized expert on IT security, he is also interviewed on a regular basis by media personalities and is a member of several panels discussing IT-security related matters.

Mr. Steinberg lives in the suburbs of New York City with his wife and two daughters.

To Shira, Penina Leora, and Miriam, with all my love.
