Discussion

If the router does not dynamically reconfigure the data security attributes as data is created and combined, there is the possibility the security attributes will not correctly reflect the data with which they are associated. Security attributes are abstractions representing the basic properties or characteristics of an entity (e.g., subjects and objects) with respect to safeguarding information. These attributes are typically associated with internal data structures (e.g., data records, buffers, and files) within the application and are used to enable the implementation of access control and flow control policies, reflect special dissemination, handling or distribution instructions, or support other aspects of the information security policy. Organizations define the security attributes of their data (e.g., classified and CUI). Security labels for packets may include traffic flow information (e.g., source, destination, protocol combination); traffic classification based on QoS markings for preferred treatment; and VLAN identification. When data is created and/or combined, data security attributes defined by organizational policy must be dynamically created and/or updated to reflect the potential change in data sensitivity and characteristics. Dynamic association of security attributes is appropriate whenever the security characteristics of information changes over time. Security attributes may change due to information aggregation issues (i.e., the security characteristics of individual information elements are different from the combined elements); changes in individual access authorizations (i.e., privileges); or changes in the security category of information. This requirement also applies to Zero Trust initiatives.

Verify the router is configured to dynamically associate security attributes with organization-defined objects in accordance with organization-defined security policies as information is created and combined.

If the router does not dynamically associate security attributes with organization-defined objects in accordance with organization-defined security policies as information is created and combined, this is a finding.
