In this article, we describe a hybrid architecture integrating firewalls, filtering routers, encryption algorithms and the proxy server as well as intrusion detection programs in an interface environment between Internet and Intranet. It is well known that the Cyber Security policy strategy has many advantages currently when it often intervenes in this environment chosen as a field of investigation for the identification of users who are not yet recognized to define a general policy of effective and efficient control. Indeed, the current approaches are based on a cyber security policy focused on a password not on which unfortunately is easily crackable using specialized programs used by hackers or pirates. However, our architecture is not based on architectures and therefore does not suffer from this limitation. On the other hand, it provides several levels of security thanks to the integration policy recommended respectively of filtering routers, proxy server and advanced encryption algorithms ensuring the security at several levels. Thus, this initiative taken, proves that our architecture makes it possible to compensate for the deficiencies of the previous in this article notably INTERNET and INTRANET.
