TENTATIVE STUDY OF HOST-NETWORK SECURITY

Host-network security is r is ing marginal technology in the field of computer security. It tries to implement the tiny granularity control of network access on the basis of consideration of the network attributes and resource attributes in the operation system. This pa per begins with introduction to the emphasis and common methods of, and problems with host security and network security, it tries to give a simple definition o f host-network security and describes the architecture of the host-network sec urity system. In the end, it makes a brief analysis of technological difficultie s and of the proposed solutions.
