The United States federal government maintains a long list of protocols for how it goes about buying equipment and supplies for its various agencies and projects. These rules are laid out in the Federal Acquisition Regulations (FAR). The Defense Federal Acquisition Regulations Supplement, or DFARS, is the subset of FAR that deals with procurement for the Department of Defense (DoD). Included in DFARS are several sections delineating the obligations of DoD contractors on safeguarding digital information. Since the initial release of rules on data security came out some five years ago, DoD has regularly updated and modified requirements on storing, transmitting, and otherwise processing “controlled information”, i.e. sensitive information with military applications.
