An intelligence officer is a person employed by an organization to collect, compile and/or analyze information (known as intelligence) which is of use to that organization. The terminology of 'Officer' is a working title, it is not to be confused with rank as in the police where sergeants are also 'Police Officers,' and enlisted Military ranks can be Intelligence Officers as well. Organizations which employ intelligence officers include armed forces, police, civilian intelligence agencies, customs agencies and private corporations.〔Strategic and Competitive Intelligence Professionals, Board of Directors, ()〕 ==Sources of intelligence== Intelligence officers make use of a variety of sources of information, including ; Open source intelligence (OSINT): Derived from publicly available sources such as the Internet, library materials, newspapers, etc. ; Communications intelligence (COMINT): Eavesdropping and interception of communications (e.g., by wiretapping) including signals intelligence (SIGINT) and electronic intelligence (ELINT). ; Imagery intelligence (IMINT): Derived from numerous collection assets, such as reconnaissance satellites or aircraft. ; Human intelligence (HUMINT): Derived from covert human intelligence sources (''agents'' or ''moles'') from a variety of agencies and activities. ; Financial intelligence (FININT): The gathering of information about the financial affairs of entities of interest. ; Measurement and signature intelligence (MASINT): Derived from collection assets that collect and evaluate technical profiles and specific characteristics of certain targeted entities. ; Technical intelligence (TECHINT): Based on scientific and technical characteristics of weapons systems, technological devices and other entities. Please note, the difference between MASINT & TECHINT is that TECHINT involves analysis of weapons systems in the custody of the organization which commissions such tests, while MASINT involves analysis, or remote sensing, of trace evidence left behind by the weapons systems ( unintended emissive byproducts, or "trails"—the spectral, chemical or RF emissions an object leaves behind which serve as distinctive signatures). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Intelligence officer」の詳細全文を読む スポンサード リンク
