communications security (COMSEC)
Definition: the protection resulting from the application of cryptosecurity, transmission security, and emission security measures to telecommunications and from the application of physical security measure to communications security information. These measures are taken to deny unauthorized persons information of value which might be derived from the possession and study of such telecommunications. COMSEC include: 1. cryptosecurity; 2. transmission security; 3. emission security; and 4. physical security of communications security materials and information. (a) Cryptosecurity: the component of communications security which results from the provision of technically sound cryptosystems and their proper use. (b) Transmission security: the component of communications security which results from all measures designed to protect transmissions from interception and exploitation by means other than cryptanalysis. (3) Emission security: the component of communications security which results from all measures taken to deny unauthorized persons information of value which might be derived from intercept and analysis of compromising emanations from cryptoequipment and telecommunications systems. (d) Physical security: the component of communications security which results from all physical measures necessary to safe guard classified equipment, material, and documents from access thereto or observation thereof by unauthorized persons. |
