Department of Defense Directive 8570 has been replaced by the DoD as Department of Defense Directive 8140. DoD 8570 is now a part of a larger initiative that falls under the guidelines of DoD 8140. DoD 8140 provides guidance and procedures for the training, certification, and management of all government employees who conduct Information Assurance functions in assigned duty positions. These individuals are required to carry an approved certification for their particular job classification. GIAC certifications are among those required for Technical, Management, CSSP, and IASAE classifications.
