​ASIS International (ASIS), the world's leading society for security professionals, originally founded in 1955 as the American Society for Industrial Security, acquired Protection of Assets in December 2003. The acquisition of this work underscores the Society's leadership role in professional education. It is the sincere desire of ASIS and its editorial staff to continue to enhance the value of this important reference.

Protection of Assets, which has been in existence since 1974, is recognized as the premiere reference for security professionals and the publisher wishes to acknowledge the two founding authors and subsequent editors.
