随着计算机技术和互联网技术的发展,敏感数据、隐私数据等这种海量的数据正以指数速度迅速膨胀,使网络安全问题日益凸显。大数据网络安全涉及技术、管理、使用等方方面面因此是一个综合性的课题。本文从目前国内外大数据的发展现状分析了包括物理安全、数据内容安全、数据传播安全、数据管理安全等多角度的大数据的网络安全;提出了一些包括访问控制、数据加密、网络隔离、入侵检测、病毒防治、安全审计、数据备份、增强安全意识等大数据网络安全的防护措施,根据以上的研究预言了大数据网络安全在新环境下的发展前景。
With the development of computer technology and Internet technology, such massive data such as sensitive data and private data are rapidly expanding at an exponential rate, which makes the issue of network security increasingly prominent. Big data network security involves all aspects of technology, management, use and so is a comprehensive issue. This paper analyzes the network security of big data including many aspects such as physical security, data content security, data dissemination security and data management security from the current development of big data both at home and abroad. Some solutions including access control, data encryption, network isolation, Based on the above research, we predict the development prospect of big data network security in the new environment.
