Industrial Security Oversight Certification (ISOC) Practice Exam

The main concept tested here is which Executive Order sets the rules for classification and protection of national security information to prevent its unauthorized disclosure. Executive Order 13526 is the current framework that defines how information is classified, what safeguards must be in place, who may access it, and how it is declassified. These provisions cover the protection of national security information from being disclosed to unauthorized individuals or entities. The other orders are older or related but have been superseded or subsumed by 13526, so they aren’t the current governing authority for protecting national security information.
