Snort是一套免费的轻量级入侵检测系统,当今的很多入侵检测系统都以其为参照。虽然Snort软件体积非常小巧,但是其部署有一定的难度。为了以更直观的方式监测系统的运行状况,通常部署Snort系统时除了要安装Snort软件本身外,还需要大量的相关软件支持。文章介绍了在Ubuntu平台上架设snort系统的具体过程。系统以MysQL数据库存储入侵检测信息,用BASE工具显示检测结果。 相似文献

As the information society enters the Internet of things era, all devices need to develop applications and drivers for comput-
er systems to identify and use. This paper introduces the process of developing the underlying device driver under the Ubuntu 16.04
system kernel. Based on the Ubuntu system kernel, source tree construction, the driver module compiling, loading and unloading are
completed. It analyzes the design method of character device driver in Ubuntu system. Finally, the character device driver designing
is successful verified through Ubuntu system. 相似文献

In information security and network management, attacks based on vulnerabilities have grown in importance. Malicious attackers break into hosts using a variety of techniques. The most common method is to exploit known vulnerabilities. Although patches have long been available for vulnerabilities, system administrators have generally been reluctant to patch their hosts immediately because they perceive the patches to be annoying and complex. To solve these problems, we propose a security vulnerability evaluation and patch framework called PKG‐VUL, which evaluates the software installed on hosts to decide whether the hosts are vulnerable and then applies patches to vulnerable hosts. All these operations are accomplished by the widely used simple network management protocol (SNMP). Therefore, system administrators can easily manage their vulnerable hosts through PKG‐VUL included in the SNMP‐based network management systems as a module. The evaluation results demonstrate the applicability of PKG‐VUL and its performance in terms of devised criteria. 相似文献
