2. Classification Levels. NATO security regulations prescribe four levels of security classification, COSMIC TOP SECRET (CTS), NATO SECRET (NS), NATO CONFIDENTIAL (NC), and NATO RESTRICTED (NR). The terms COSMIC and NATO indicate that the material is the property of NATO. Another marking, "ATOMAL," is applied to U.S. RESTRICTED DATA or FORMERLY RESTRICTED DATA and United Kingdom Atomic Information that have been released to NATO. ATOMAL information is marked COSMIC TOP SECRET ATOMAL(CTSA), NATO SECRET ATOMAL (NSA), or NATO CONFIDENTIAL ATOMAL (NCA).
