An Approach for Alert Raising in Real-Time Data Warehouses
نویسندگان
چکیده
This work proposes an approach for alert raising within a real-time data warehouse environment. It is based on the calculation of confidence intervals for measures from historical facts. As new facts arrive to the data warehouse on a real-time basis, they are systematically compared with their appropriate confidence intervals and alerts are raised when anomalies are detected. The interest of this approach is illustrated using the particular real world use case of technical analysis of stock data.

Real-Time intrusion detection alert correlation and attack scenario extraction based on the prerequisite consequence approach
Alert correlation systems attempt to discover the relations among alerts produced by one or more intrusion detection systems to determine the attack scenarios and their main motivations. In this paper a new IDS alert correlation method is proposed that can be used to detect attack scenarios in real-time. The proposed method is based on a causal approach due to the strength of causal methods in ...
متن کاملA Reliability Approach on Redesigning the Warehouses in Supply Chain with Uncertain Parameters via Integrated Monte Carlo Simulation and Tuned Artificial Neural Network
In this paper, a reliability approach on reconfiguration decisions in a supply chain network is studied based on coupling the simulation concepts and artificial neural network. In other words, due to the limited budget for warehouse relocation in a supply chain, the failure probability is assessed for determining the robust decision for future supply chain configuration. Traditional solving ...
متن کاملReconfiguration of Supply Chain: A Two Stage Stochastic Programming
In this paper, we propose an extended relocation model for warehouses configuration in a supply chain network, in which uncertainty is associated to operational costs, production capacity and demands whereas, existing researches in this area are often restricted to deterministic environments. In real cases, we usually deal with stochastic parameters and this point justifies why the relocation m...
متن کاملA Three-Echelon Multi-Objective Multi-Period Multi-Product Supply Chain Network Design Problem: A Goal Programming Approach
In this paper, a multi-objective multi-period multi-product supply chain network design problem is introduced. This problem is modeled using a multi-objective mixed integer mathematical programming. The objectives are maximizing the total profit of logistics, maximizing service level, and minimizing inconsistency of operations. Several sets of constraints are considered to handle the real situa...
متن کاملSecuring Data Warehouses from Web-Based Intrusions
Decision support for 24/7 enterprises requires 24/7 available Data Warehouses (DWs). In this context, web-based connections to DWs are used by business management applications demanding continuous availability. Given that DWs store highly sensitive business data, a web-based connection provides a door for outside attackers and thus, creates a main security issue. Database Intrusion Detection Sy...
