计算机在运行的过程中存在各种各样的安全威胁,而我国计算机网络发展起步比较晚,在安全防护方面仍然做的不够好。比如系统自身存在的安全威胁、用户操作存在的威胁、恶意攻击以及垃圾邮件的影响,其次还有计算机病毒方面的威胁等这些因素均是造成企业计算机网络安全的主要因素。在平时的工作中必须充分处理这些威胁因素,提高计算机信息完全防护措施,最大限度的减少计算机威胁给用户带来的危害。 There are various kinds of security threats in the process of computer operation, while the development of computer network in our country started relatively late, and the security protection is still not good enough. Such as the system’s own security threats, user operations threats, malicious attacks and spam impact, followed by computer viruses and other threats are the main factors that cause the computer network security. In normal work, we must fully deal with these threats, improve the complete protection of computer information and minimize the harm caused by computer threats to users.
