* global layer: formed by the highest-level nodes, e.g., root and other directory nodes logically close to the root. The directory tables in these nodes are rarely changed.
* administrational layer: formed by the directory nodes managed within single organization. The nodes in this layer are relatively stable although less stable than those in global layers.
* managerial layer: formed by the nodes that may change regularly, e.g., nodes representing hosts in the LAN. The nodes in this layer are also maintained by end users of a DS.
In distributed systems, securityis the combination of availability, integrity, and confidentiality. A dependable distributed system is thus fault tolerant and secure.8. Security
