远程监控Agent的体系结构及其环境安全态势 评估模型

为满足对抗性环境中建立远程监控系统的需求,提出一种面向任务的可重构Agent体系结构AGORA。AGORA具有反射型和思考型Agent体系结构的特点,由感知单元、控制单元和执行单元组成,并可根据Agent的具体任务,动态替换其执行单元中的任务执行模块。在深入分析Agent体系结构的工作原理、生命期规划、工作状态转移、环境感知和行为决策等的基础上,提出了Agent的环境安全态势评估模型,并在Windows环境下选择主机防病毒、主机防火墙、网络监视和系统进程管理等软件作为Agent的环境安全威胁因素,进而根据相应的软件进程状态确定各自的威胁级别,以验证Agent环境安全态势评估模型。所建立的Agent体系结构及其环境安全态势评估模型,对于开发对抗性环境中基于Agent的远程控制系统具有重要指导价值。

The Architecture and Safety Situation Evaluation Model of Agent for Remote Supervision

To meet the need of constructing a remote surveillance system within the oppositional environment,the Architecture of Goal-Oriented Rebuild-able Agent(AGORA),which combines the characteristics of reactive and deliberative architecture of agent,was proposed.It consists of environment perception unit,self control unit and acting unit,and its acting module can be replaced under the given situation.Through the detailed analyses of working procedure,lifecycle planning,working state transformation, environment perception and action-decision-making of the agent,a model was presented for the agent to evaluate its safety situation for its survival from the threats.Under the Windows operating system,the software of anti-virus,host-based firewall,network monitor and process manager were selected as the threats to the agent,and the degree of its influence was judged depending on each process's status to verify the model.The architecture of the agent and its safty situation evaluation model to evaluate its safety situation have great values for the development of agent-based remote control system under the counteracting environment.
