The proposed framework involves layers of security and maintenance network segments under control of the administrators. This book describes various techniques for properly analyzing the security model. The analysis permits system administrators to identify and patch up inaccuracy in the configuration of the different part of the framework. The book demonstrates the application of various activities and permissions through certain policies and analyzing collected logs. To improve the joint defense technologies, this book presents a vast research to propose an innovative joint defense technology which is based on novel hybrid architecture, called Micro-firewalls framework. The stimulate of this research seeks collaboration of different entity which, could reach to the capability of distributed points of security policy; The achieved is multi-layer security defense model that by using different proposed algorithm, establish a dynamic security and provide domain security authentication.
