An Efficient Data Analysis Framework for Online Security Processing

Figure 3

Online data analysis framework: We integrate MapReduce model with query indexes strategy to efficiently support cloud data stream querying. In particular, in our index framework, we build LCN-Index on Mapper and build multiattribute indexes on Reducer. We focus on the highlighted components, local LCN-Index in Mapper and multiattribute indexes matching in Reducer. In Section 3, we will introduce LCN-Index schema. In Section 4, we will introduce the multiattribute index algorithm.
