The National Computer Security Center has established an aggressive program to study and implement computer security technology, and to encourage the wide-spread availability of trusted computer products for use by any organization desiring better protection of their important data. The Trusted Product Evaluation Program, and the open and cooperative business relationship being forged with the computer and telecommunications industries, will result in the fulfillment of our countrys computer security requirement. We are resolved to meet the challenge of identifying trusted computer products suitable for use in protecting information.
