【摘要】 人类从自然界获得解决科学难题的灵感,借鉴自然界自身的规律,解决人类面临的科学问题已经成为现代科学研究中的一个非常新的研究思路。本文在认识生物免疫系统运行机理的基础上,通过参考国内外计算机免疫系统的研究成果提出基于系统调用的计算机免疫系统模型的。在该模型中借鉴了生物免疫系统的一些特点来完成识别“自我”与“非我”,进而消除“非我”,为进行自身反应强度的调节提供了一个完善的框架基础。并在此基础上,构建一个自治、自适应的信息安全防护系统,使它能通过动态分析机制实时监测进程的异常情况,及时发出警报,有效弥补了其他静态防御工具的不足。本文介绍了检查点机制,以及检查点一致性问题,提出了检查点一致性算法,运用检查点技术保存和恢复进程上下文及部分系统上下文,以及一些和进程运行相关的东西,例如打开文件的状态,以及其他一些与主机状态相关的进程运行环境,实现进程的回滚、备份、恢复,并提出了几种提高检查点效率的方法,提出了在Linux系统下检查点机制的用户级实现。更多还原

【Abstract】 It becomes a very new method in research field that people get inspiration from the natural to solve the science problem, research the rules of the natural and in the end solve the problem that people faced. After studying the mechanism of the biologic immune system and referring the returns of computer immune system at home and abroad, the computer immune system model based on system call is put forward. In this model, some traits of the biologic immune system are utilizing to distinguish non-self from self, eliminate non-self and provide a frame for adjusting the intensity of self-response. And based on this, an autonomic and self-adapting information safety system is constructed. It can monitor the processes real-time by dynamic analytic mechanism and give the alarm in good time, which effectively compensates the shortage of the other static tools. This paper recommends checkpointing mechanism and expounds chekpointing accordance algorithms. This paper applies checkpointing to achieve the rollback backup and restarting of the process by reserving and restarting the process context ,the system context and something relevant with the process running, for example the states of the opening papers and the environment relevant with the mainframe states.And the paper expounds some kinds of ways to improve the efficiency of the checkpointing and the realization of the checkpointing under user level in the Linux.更多还原
