计算机网络安全问题和对策研究

Security Problems and Countermeasure Research of Computer Network

计算机网络给人们工作生活带来极大便利的同时,也给广大用户带来潜在的隐患和巨大的伤害。如何防范和处理计算机网络的安全问题已成为当前的重要课题。从计算机网络的安全问题入手,初步探讨计算机网络的安全对策。分析了常见的病毒攻击、系统漏洞攻击、欺骗类攻击、黑客攻击等网络攻击方法,探讨访问控制策略、信息加密策略、病毒攻击的应对策略、系统漏洞攻击的应对策略、黑客攻击的应对策略等,并对常规密码算法和公钥密码算法进行了分析。

The computer network not only brings great conveniences of life, but also to the vast number of potential users of the dangers and enormous harm. How to prevent and deal with the security of computer networks has become an important issue at present. From the computer network security problems, to explore the initial response of computer network security. Analysis of the common viruses,system vulnerability attack, deception attack, hacker attack, such as network attack methods of access control policy, information encryption strategy, virus attacks, reply strategies, the system exploits the reply strategies, hacker attack reply strategies to deal with issues, conventional cryptographie algorithm and public key cryptography algorithm are analyzed.
