Abstract

Objective : The numerous protocols and products in the existing network architecture not just complicates the network, but also require that the administrators master the intricacies of configuring the hardware and software, setting the rules, and monitoring and creating reports. In this paper, we present a component that can control the communication between devices from a single point. Methods: In this paper, we present a component developed using Python and OpenFlow protocol over POX controller. This is a layer 3-layer 4 component that converts all the switches in a software defined network to filtering devices thus functioning as a communication blocker or packet filter between machines in the network. Findings: Our test results show that this component is distributive and topology independent and functions without degrading the performance of the controller. Improvement: To the best of our knowledge, our component is one of the first for POX controller since it is topology independent, restrictive, and functions on the basis of IP addresses and not by blocking of MAC addresses.

Abstract

Background/Objectives: The Aim of this research work to demonstrate that the security enhancement of data warehousing, the methods face major challenges in integrity management and have the responsibility to restrict the unauthorized user. Methods/Statistical Analysis: There are many access control methods discussed earlier for the problem of integrity management, and some of them have been discussed using the user profiles. Still they suffer from the problem of efficiency in integrity management. Findings: To overcome such issues, in this paper a multi-user profile orient access depths measure based integrity management is proposed. The method maintains a set of Meta data which keep track of data objects in a hierarchical manner according to their importance and sensitivity of the data. The method first identifies a set of objects being specified from the input query and the sensitive tree; the method computes the access depthness measure. The access depthness is computed based on the level of objects being called and the access level the user has been given and the number of objects the user has access. Application/Improvement: Based on computed access depths measure user query is being processed, and the method improves the performance of integrity management.
