Big Data LifeCycle: Threats and Security Model

Big data is an emerging term referring to the process of managing huge amount of data from different sources, such as, DBMS, log files, postings of social media. Big data (text, number, images... etc.) could be divided into different forms: structured, semi-structured, and unstructured. Big data could be further described by some attributes like velocity, volume, variety, value, and complexity....

Aggregation of log-linear risks

In this paper we work in the framework of a k-dimensional vector of log-linear risks. Under weak conditions on the marginal tails and the dependence structure of a vector of positive risks we derive the asymptotic tail behaviour of the aggregated risk and present an application concerning log-normal risks with stochastic volatility.
