| 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, files) within the network element 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. The term security label is often used to associate a set of security attributes with a specific information object as part of the data structure for that object (e.g., user access privileges, nationality, affiliation as contractor). A security label is defined as: the means used to associate a set of security attributes with a specific information object as part of the data structure for that object. Examples of a security label of a packet could be traffic flow (source, destination, protocol combination), traffic classification based on QoS markings for preferred treatment, VLAN identification, etc.
Reconfiguring security attributes is not a function of DNS. |
