When compromise of aggregated agency data would have a significant impact on the agency, agencies must encrypt that data with an approved algorithm and protocol whenever it crosses networks that are insecure or unprotected, for example the Internet, public infrastructure or networks outside agency control.
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.
