Abstract: The development and application of Linux system brings new opportunities and challenges for the development of computer network system. The open source and free operation mode of Linux system establishes a docking platform for computer equipment and network system, so as to ensure that operators can conduct directional search on network resources through the system. However, from the perspective of network operation system, security risk has always been a difficult problem for technicians to overcome, the dynamic operation of network information will seriously increase the prevention and control burden of the network security system, causing computer users to face the risk of data information leakage. Based on this, this paper took Linux system as the starting point, pointed out the problems existing in the computer network security management, and made an in-depth analysis of the attack and defense countermeasures under the network system.
Keywords: Linux system;computer networks;safety management;offensive and defensive strategies
Linux作为一种开放式、免费式的操作系统,依托于系统内的稳定性、安全性、荷载性和资源利用性等,在行业市场中占据较大的份额[1,2]。在Linux系统的实际应用过程中,用户可在网络上查找到系统自身的运行程序、数字化工具等,如halt、shutdown、init和reboot等指令。此等共享资源为用户对Linux系统的操控提供一定的便利,但同时也為黑客提供攻击渠道。黑客通过服务响应攻击、密码破解攻击、溢出攻击、IP地址隐藏攻击等,可对Linux系统进行大范围攻击,对用户的数据信息资源造成严重威胁。为此,技术人员应积极研发有效的防控技术,为用户本身提供信息安全保障。
1 Linux系统特性论述
Linux作为Unix操作系统的运行平台,其内控中心为宏内核,对于当前主流操控系统的混合内核来讲,宏内核框架以其简化式信息处理形式维系市场上的受众比。……
