Research On Security Model For Financial Information System

Fittting for the security of financial information system , a access control mode , a system mode and a netwok security mode are established.The requirement of the access control is described in this article.The base mode with the tree-struct and the mode with constrains are proposed.The security properties of base mode and more security of the mode with constrain are analysed.To manage roles and workflows ,A authorization from role to role is established .With those modes,the system have very good characteristic.Suiting the access control mode,a system mode is proposed.Security property description parameter is used in this mode.The access control based in nucleus workflow with this parameter.With Agent and Corba,nucleus workflow can be re-used ,roles and workflows can be re-defined.The re-using of system are improved.The crierion of if workflow struct reasonable is gaven.The arthritic of Agents is given too.After analysyed of PKL SSL IPSec, the network security mode is esblished based on IPSec .We improve on the phase 1 of IKE,the key exchange can be more security.
