When industry supplies an agency with information technology services and functions from off-site, the agency must accredit the systems the contractor uses to a standard no lower than the minimum applied to its own systems. A review report from an independent third party, prepared under ISAE 3402 (the standard for assurance reporting on controls at a third party service organisation), is one way to meet this.
This control maps to 1 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 1 it maps to, and the evidence behind each claim, over MCP and REST.
