Efficient abnormality diagnosis scheme on network security

Abstract

Network security rely mainly on the hardware, software security and the safety of the coordination to fulfill. Network security level is not fixed, users are not the same, the network security levels are also different, such as ordinary users need to moderate level of security will be, but for business users in the higher levels of security needs. But the network security is a discipline by many with high comprehensive application technology type, and network environment is very typical of the variety and complexity, which lead to the network security vulnerability. At present, the network security situation facing more complex and severe, if only depend upon the traditional firewall technology, the password techniques, and access control technology, hard to provide effective security barrier network. Therefore need to cooperate to use different from passive safety measures to protect the intrusion detection technology to carry out the network security exception diagnosis, for the new situation of the network security with more powerful guarantee. © 2013 Springer Science+Business Media.
