Abstract:

The security mechanism of open source platform is not sophisticated,especially on user authentication and log audit.The potential safety problems of open source platform were analyzed.Based on the open source Hadoop platform,the user authentication based on Giano,and the efficient log audit based on rules were proposed.Combined with the practical application of Baidu,the effectiveness of the technical scheme was expounded.The technical scheme has certain universality,and it can be flexibly used according to the current technological environment of the enterprise.

Key words: big data security, user authentication, log audit, digit security
