1计算机网络面临的主要威胁就目前而言,计算机网络安全隐患的主要来源有三个,一是计算机系统本身的问题,如安全漏洞、后门程序等,给病毒的入侵和黑客的攻击提供了便利,影响了计算机网络信息的安全性,如比较常见的缓冲区溢出攻击等;二是网络通信系统中存在的问题,现阶段,计算机网络中应用最为广泛的TCP/IP协议本身存着一定的缺陷和问题,没有充分考虑网络信息传输对于安全性的要求,同样给不法分子的入侵攻击提供了可能;三是网络配置不
1 Main threats facing computer networks Currently, there are three main sources of potential computer network security risks. First, the problems of computer systems, such as security breaches and backdoors, provide convenience for virus intrusion and hacker attacks. Affecting the security of computer network information, such as the more common buffer overflow attacks; the second is the network communication system problems, at this stage, the most widely used computer network TCP / IP protocol itself has some defects and Problem, did not give full consideration to the network security requirements for information transmission, the same to the criminals to provide the possibility of invasion and invasion; Third, the network configuration is not
