随着智能手机、平板计算机等移动载体的流行,社交媒介、云计算、移动互联网的兴起,传统的网络安全防御边界已越来越模糊,网络开始进入无边界时代。随之而来的,是现代混合安全威胁的泛滥,特别是自去年以来国内外金融机构客户信息及机密数据泄漏的信息频出,传达出对传统的标准安全产品和安全技术的质疑。如今我们需要更新一代的内容安全产品和技术,不仅要保障网络周边和终端安全,而且还要识别、分类和理解各种类型的内容,并作出放行、拦截或隔离的准确判断。更重要的是,这些技术和安全产品必须达到时下潮流的移动办公的内容安全标准,在传统防御边界逐渐模糊的情况下提高各硬件设备、软件平台之间的协同效应,使整个内容 With the popularization of mobile carriers such as smart phones and tablet computers, the rise of social media, cloud computing and mobile internet, the traditional network security defense boundaries have become increasingly blurred and the network has entered an era of borderless. What followed was the proliferation of modern hybrid security threats, especially the frequent leaks of customer and confidential data from domestic and foreign financial institutions since last year, sending out questions about the traditional standard security products and security technologies. Now we need a new generation of content security products and technologies that not only ensure network perimeter and endpoint security, but also identify, classify and understand all types of content and make accurate judgments about release, interception or isolation. More importantly, these technologies and security products must meet the trend of the content security standards of the mobile office in the current, gradually diminishing the traditional defensive boundary conditions to improve the synergies between various hardware devices, software platforms so that the entire content
