自二十世纪90年代以来,计算机技术、互联网技术飞速发展,与之对应的数据也迅猛增长,伴随而来数据的安全问题。海量的数据包括敏感数据和隐私数据。大数据网络安全涉及到了管理、技术以及使用等多个方面。本文正是基于这一背景,以确保大数据环境下的网络安全为目的,首先分析了大数据环境下对网络安全的现状;其次就大数据环境下网络安全的内涵进行了分析;再次就如何确保大数据环境下的网络安全提出了几点浅见;最后对大数据环境下网络安全的发展趋势进行了展望。 Since the 90s of the 20th century, the rapid development of computer technology and Internet technology has led to the rapid growth of the corresponding data and the data security problems. Massive data includes sensitive data and private data. Big data network security involves a number of aspects of management, technology and use. Based on this background, this paper aims to ensure network security in big data environment. Firstly, the status quo of network security in big data environment is analyzed. Secondly, the connotation of network security in big data environment is analyzed. In the big data environment to ensure the safety of the network put forward a few humble opinion; Finally, the development trend of network security in the big data environment is prospected.
