Network Security Performance Analysis Based on Netflow

Abstract

With the continuous development of network technology, the size and complexity of network data are increasing, network security has become a topic of constant concern, so the network environment for real-time detection and control, to ensure that the network security performance continues to improve to become an urgent problem to be solved. Therefore, new methods must be used to improve the performance of network security. Netflow, as a new technology, provides a new path for the improvement of network security performance. Therefore, on the basis of Netflow technology, this paper proposes a network security test method for Netflow network data analysis. It is to take source IP as the main research object, from the perspective of a network attack, to study the manifestation of Netflow network data in network security issues. By analyzing the abnormal behavior of IP access, the corresponding network security problem is simulated through practice. And its feature vector analysis and detection, and then use the algorithm of invalid links, network behavior scanning, network DOS attack, such as abnormal access behavior related IP analysis. So you can get an accurate network security problem.
