Enrichment (EN)

Disambiguation: CONFIDENTIAL is a U.S. government classification marking (legal instrument), NOT generic corporate confidentiality. May appear in archive as marking, marking abbreviation '(C)', or as a subject of procedural documents governing access to classified materials.

CONFIDENTIAL is the lowest classification level in the United States government classification system, governed by Executive Order 13526 and DoD regulations. Applied to information whose unauthorized disclosure reasonably could be expected to cause damage to national security, it ranks below Secret and Top Secret. Documents marked CONFIDENTIAL require specific handling, storage, marking, and access controls; authorized personnel with appropriate security clearances and legitimate need-to-know may access such materials. In UAP archives, the marking indicates the document's classification status and restricts distribution accordingly.

Desambiguação: CONFIDENTIAL is a U.S. government classification marking (legal instrument), NOT generic corporate confidentiality. May appear in archive as marking, marking abbreviation '(C)', or as a subject of procedural documents governing access to classified materials.

CONFIDENTIAL é o nível mais baixo de classificação do sistema de classificação do governo dos Estados Unidos, regido pela Ordem Executiva 13526 e regulações do DoD. Aplicado a informações cuja divulgação não autorizada razoavelmente poderia causar dano à segurança nacional, ele está abaixo de Secret (Secreto) e Top Secret (Ultrassecreto). Documentos marcados CONFIDENTIAL requerem controles específicos de manuseio, armazenamento, marcação e acesso; pessoal autorizado com credenciais de segurança apropriadas e necessidade legítima de saber podem acessar tais materiais. Em arquivos de UAP, a marcação indica o status de classificação do documento e restringe a distribuição adequadamente.
