面向容忍入侵的自治愈应用服务器设计与实现

摘要

针对现有容忍入侵应用服务器在自治愈方面的不足,提出了一种面向容忍入侵的自治愈应用服务器的构建方法.在容忍入侵应用服务器的基础上,设计了自治愈功能组件,包括检测部件、管理部件和执行部件,将自治愈功能透明地加入到容忍入侵应用服务器中,解决了容忍入侵应用服务器中存在的隐性入侵、软件老化以及容侵前提条件易遭破坏的问题,进一步提高了容忍入侵应用服务器的可靠性和生存性.最后在项目组研发的容忍入侵应用服务器平台--JANTM中实现了对自治愈功能的支持.%Aiming at the current intrusion-tolerant application server' s limitation for self-healing, a method to design an intrusiontolerant oriented self-healing application server is proposed.By the way of establishing a self-healing functional components, including the detection components, management components and implementation components, we add self-healing capabilities into the intrusiontolerant application server.It solves some problems in the intrusion-tolerant application servers, for example the hidden intrusion,software aging, and the vulnerable prerequisite of intrusion tolerance, and further enhances the reliability and survivability of the intrusiontolerant application server.Finally, an intrusion-tolerant oriented self-healing application server is realized, JANTM is built (J2EE based adaptive intrusion tolerant middleware) which is developed by our project team.
