Information Systems Security Products and Services Catalogue.

The National Security Agency NSA manages a variety of information systems security programs. These programs had long been divided into two main areas Communications Security CONSEC including TEMPEST, and Computer Security COMPUSEC. COMSEC is protective measures designed to prevent unauthorized access, disclosure, acquisition, manipulation, modification, or loss of information while it is being communicated, regardless 0 the medium used -e.g., telephone, microwave, or satellite. COMPUSEC is protective measures designed to prevent deliberate o inadvertent unauthorized access, disclosure, acquisition, manipulation, modification or loss of information while it is being automatically processed or stored. These two primary disciplines - COMSEC and COMPUSEC - were organizationally joined at NSA in order to most effectively meet the nations need for a total information systems security program. From the previous program divisions and separate disciplines have come lists of information systems security products and services that have either been evaluated against established standards, or been endorsed by NSA as having met the requirements and standards set for these products by the government. These lists now make up tI Information Systems Security Products and Services Catalogue.
