Adaptive Approach to Network Security
The security of information exchange between the parts in the teleinformatic infrastructure is one of the crucial topics. During the protecting the infrastructure of the organization, one can use a lot of mechanisms which are often based on the cryptographic primitives. Traditionally, the security officers model the protection system to be as strong as it is possible. However, the level of protection of information is often much higher than it is necessary to meet potential threats. Since the level of security strongly affects the performance of the whole system, the excessive protection decreases its reliability and availability and, as a result, its global security. The appropriate security level can be estimated by means of different quality of protection models. In this paper we are going to present the approach how to introduce the adaptability to the network. We are basing on the adaptable security model for dynamic environment which calculates the protection level by means of the risk management processes. The analysis is assisted by the security management tool (SPOT) which visualizes and optimizes the adaptable model mentioned above. Finally, we present the case study introducing the network adaptability of the cryptographic protocol.
