在当今网络化的世界中,计算机已成为人类社会中不可缺少的一部分,不论是生活,还是工作中对计算机的依赖程度日趋加深。网络很容易受到攻击,计算机信息和资源也很容易受到黑客的攻击,甚至是后果十分严重的攻击,诸如数据被人窃取,服务器不能提供服务等等,因此,计算机安全也越来越为人们重视。由此推动了计算机硬件、防火墙、入侵检测、虚拟专用网、访问控制、面向对象系统的安全等各种网络、信息安全技术的蓬勃发展。本文就新木采油厂计算机硬件维护、Internet信息安全以及防火墙工作原理进行简单论述,以供工作中使用计算机作为理论参考依据。
In today’s networked world, computers have become an indispensable part of human society, both in life and in their work, and their dependence on computers has deepened. The network is vulnerable to attack, computer information and resources are also vulnerable to hackers, and even very serious consequences of attacks such as data being stolen, the server can not provide services, etc. Therefore, computer security is also more and more attention . As a result, various networks such as computer hardware, firewall, intrusion detection, virtual private network, access control, and object-oriented system security have been promoted, and the information security technology has been booming. This paper briefly discusses the computer hardware maintenance, Internet information security and the working principle of the firewall in Xinmu Oil Production Plant, in order to use the computer in the work as the theoretical reference.
