D3-AMED Access Mediation

Access mediation is the process of granting or denying specific requests to: 1) obtain and use information and related information processing services; and 2) enter specific physical facilities (e.g., Federal buildings, military establishments, border crossing entrances). Access mediation decisions should enforce least privilege by granting access for scoped durations to prevent privilege creep and, where applicable, implement just-in-time (JIT) access. Denial decisions may prevent initial access or terminate access that has already been granted, ensuring continuous enforcement of security policies.
