英语翻译
网络安全是指网络系统的硬件、软件及其系统中的数据受到保护,不因偶然的或者恶意的原因而遭受到破坏、更改、泄露,系统连续可靠正常地运行,网络服务不中断.网络安全从其本质上来讲就是网络上的信息安全.从广义来说,凡是涉及到网络上信息的保密性、完整性、可用性、真实性和可控性的相关技术和理论都是网络安全的研究领域.网络安全是一门涉及计算机科学、网络技术、通信技术、密码技术、信息安全技术、应用数学、数论、信息论等多种学科的综合性学科.
网络安全的具体含义会随着“角度”的变化而变化.比如：从用户（个人、企业等）的角度来说,他们希望涉及个人隐私或商业利益的信息在网络上传输时受到机密性、完整性和真实性的保护,避免其他人或对手利用窃听、冒充、篡改、抵赖等手段侵犯用户的利益和隐私.
