网络安全风险管理维护
摘要：
众所周知，随着全球互联网的发展与运用，各种网络信息风险日益加剧，不仅是个人，企业以至国家都会受到网络信息泄露的威胁，因此需要做出各种各样的防范措施来抵御和预防这些普遍的、表面的、潜在的网络信息安全威胁。
目前，很多涉及到国计民生的重要信息系统，如金融，电信，电力，交通，金融，医疗卫生，国防，企业等信息系统，都是基于庞大的网络互联来运作的。而社会各种信息化和网络化带来便利的同时也受到各种不同的安全威胁，例如计算机病毒，特洛伊木马，网络蠕虫，口令破解，协议攻击，漏洞扫描攻击，网络入侵攻击，逻辑炸弹等，由于信息都是存储在名为服务器的联网的计算机中，各种潜在安全威胁都难以防范，因此需要以专业的眼光来进行专业的网络安全防范措施，抵御措施，应急措施等。如何专业的防范，就需要先找出问题所在。

Abstract： As we all know, with the global development and use of the Internet, a variety of network information security risks growing, not only individuals, corporates and the country will be threatened by network information, you need to make a variety of preventive measures to combat and prevent these common, surface and potential information security threats.
At present, many important information systems related to people's livelihood, such as finance, telecommunications, power, transportation, finance, health, defense, enterprise information systems, is based on a vast network of interconnected to operate. Social Informationization and networking brought convenience but also by a variety of security threats, such as computer viruses, Trojan horses, worms, password cracking, attacks, vulnerability scanning attacks, network intrusions, such as logic bombs, because the information is stored on networked computers called servers, A variety of potential security threats are difficult to prevent, therefore need to look professional for professional network security precautions against the measures, emergency measures, and so on. Prevention of professional, you need to first find out where the problem lies.
