摘要: Interorganization computer networks support person-to-person communication via electronic mail; exchange of cad/cam data, software modules, or documents file transfer; input to an order-entry accounting system a database query and update protocol; use shared computational resources asynchronous message protocol remote login. In most such interorganization arrangements, the set that organization wants make accessible outsiders is significantly smaller than it remain strictly-internal (i.e., employees only). addition, because potential user person (or machine) outside boundaries organization, damage associated with undesired can be high. Because these characteristics, Networks (ION's) have unique usage-control requirements.
