AC-4(5) Embedded Data Types
Control enhancement of AC-4 Information Flow Enforcement
Control
Enforce [Assignment: limitations] on embedding data types within other data types.
Discussion
Embedding data types within other data types may result in reduced flow control effectiveness. Data type embedding includes inserting files as objects within other files and using compressed or archived data types that may include multiple embedded data types. Limitations on data type embedding consider the levels of embedding and prohibit levels of data type embedding that are beyond the capability of the inspection tools.
Need AC-4(5) implemented and evidenced?
We assess where you stand against this control, document the gap, and build the remediation plan your auditor and your board will both accept.
