Starting from the security, this paper puts forward some measures for constructing the network security defense system and solving the network security problems by adopting the firewall technology, NAT technology, VPN technology, network encryption technology, identity authentication technology, invasion detection technology, multi-level virus defense system.
Based on them, an open and common security defense interaction model-OCIM(Open and Common Interaction Model) model is put forward, which includes IAEP (InterAction Exchange Protocol) and IAMEF (InterAction Message Exchange Format).
在此基础上，提出了一种开放式通用安全防护联动模型——OCIM模型(Open and Common Interaction Model)，其中包括联动交换协议IAEP(InterAction Exchange Protocol)和联动消息数据交换格式IAMEF(InterAction Message Exchange Format)。
In security defense measures, the author advances a dynamic defense system, the core of which is Intrusion Detection System, namely the linkage with Intrusion Detection System, Vulnerability Scanners System and Firewalls System.
The experiment results show that this model is a good solution to the network security defense.
Thus the potential intruder is faced with an ever changing security defense system.
Each of these developments presents food safety regulatory and food security/defense challenges for FDA.
Any run-time security defense will impose performance costs, due to additional run-time checks that it is performing.
This paper firstly describes the background and definition of information security countermeasure, then discusses their research topic and present development. At the same time, a series of valuable quesions and directions are presented in the fields of cryptography, intrusion detection, response process, security defense.
With the development of the information service,loog-distance education and electronic commerce,the security problems is more important.This paper puts forward solutions for the internet's security defense,Practial safe defense and enterprises special net.
The "U.S.-Japanese Joint Security & Defense Declaration" was followed by great changes in the relation of U.S.-Japa-nese military alliance. To some extent, U.S.-Japanese military alliance means NATO of Asia-Pacific region.
