Research on Core Technology Based on Computer Information System Security Architecture

With the high development of computer technology and communication technology, computer system is facing a growing number of attacks.So, the security of computer system has become study focus in the world. This paper described the security architecture of the computer systems, mainly:ISO7498-2 security architecture and adaptive network security system model.Then, the requirements of the security technology were described by the information security and physical security.Finally, the core technologies of security system were studied in detail: encryption and firewall technology.
