Discussion

Enforcing allowed information flows based on metadata enables simpler and more effective flow control. Metadata is information used to describe the characteristics of data. Metadata can include structural metadata describing data structures (e.g., data format, syntax, and semantics) or descriptive metadata describing data contents (e.g., age, location, telephone number). For cross domain solutions, security attributes are defined as, at a minimum, source and destination address. This requirement also applies to Zero Trust initiatives.
