电脑带来的坏处英语作文
计算机网络面临的安全威胁大体可分为两种:一是对网络本身的威胁,二是对网络中信息的威胁。对网络本身的威胁包括对网络设备和网络软件系统平台的威胁;对网络中信息的威胁除了包括对网络中数据的威胁外,还包括对处理这些数据的信息系统应用软件的威胁。
影响计算机网络安全的因素很多,对网络安全的威胁主要来自人为的无意失误、人为的恶意攻击和网络软件系统的漏洞和“后门”三个方面的因素。
人为的无意失误是造成网络不安全的重要原因。网络管理员在这方面不但肩负重任,还面临越来越大的压力。稍有考虑不周,安全配置不当,就会造成安全漏洞。另外,用户安全意识不强,不按照安全规定操作,如口令选择不慎,将自己的账户随意转借他人或与别人共享,都会对网络安全带来威胁。
人为的恶意攻击是目前计算机网络所面临的最大威胁。人为攻击又可以分为两类:一类是主动攻击,它以各种方式有选择地破坏系统和数据的有效性和完整性;另一类是被动攻击,它是在不影响网络和应用系统正常运行的情况下,进行截获、窃取、破译以获得重要机密信息。这两种攻击均可对计算机网络造成极大的危害,导致网络瘫痪或机密泄漏。
网络软件系统不可能百分之百无缺陷和无漏洞。另外,许多软件都存在设计编程人员为了方便而设置的“后门”。这些漏洞和“后门”恰恰是黑客进行攻击的首选目标。
