| Dynamic association of security attributes is appropriate whenever the security characteristics of information change over time. Security attributes may change because of 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), and changes in the security category of information.
Security attribute assignments are representations of the properties or characteristics of an entity. Thus, if a security policy is changed or data is created or changed, the system will dynamically reconfigure and apply security attributes in accordance with the security policy.
Reconfiguration of security attributes is not a function of the firewall. |
