Coordination of security levels for Internet architectures

Abstract

Internet systems provide a variety of ways for exchanging information, contain a large amount and variety of data, and have become quite complex, making them vulnerable to attacks from determined hackers. There are many products currently being used to stop these attacks but they suffer from a lack of completeness, only applying to one type of attack. Several mechanisms are needed for a comprehensive defense but this incurs the problem of their lack of coordination, which can be exploited for attacks. We propose a way to coordinate different mechanisms based on a unified object-oriented modeling approach and a hierarchical architecture whose layers define the scope of each security mechanism.
