【Abstract】 It is the basis for security of information systems to establish an information system security model.For information systems the security models in existence have showed insufficiency obviously.To adapt the properties of highly opened and distributed network based information systems today,through the definition of security domains,the new model gives study on unique domain system,simple system and complex system respectively.A model adaptable for the security of information systems is presented.Thus a basis for the security of information systems is found theoretically.更多还原
