This research explored how cyber security risks are managed across UK Critical National Infrastructure (CNI) sectors following implementation of the 2018 Networks and Information Security (NIS) legislation. Being in its infancy, there has been limited study into the effectiveness of this national framework for cyber risk management. The analysis of data gathered through interviews with key stakeholders against the NIS objectives indicated a collaborative implementation approach to improve cyber-risk management capabilities in CNI sectors. However, more work is required to bridge the gaps in the NIS framework to ensure holistic security across cyber spaces as well as non-cyber elements: cyber-physical security, cross-sector CNI service security measures, outcome-based regulatory assessments and risks due to connected smart technology implementations alongside legacy systems. This paper proposes ten key recommendations to counter the danger of not meeting the NIS key strategic objectives. In particular, it recommends that the approach to NIS implementation needs further alignment with its objectives, such as bringing a step-change in the cyber-security risk management capabilities of the CNI sectors.

The present paper describes some of the results obtained in the Faculty of Computer Systems and Technology at Technical University of Sofia in the implementation of project related to the application of intelligent methods for increasing the security in computer networks. Also is made a survey about existing hybrid methods, which are using several artificial intelligent methods for cyber defense. The paper introduces a model for intrusion detection systems where multi agent systems are the bases and artificial intelligence are applicable by the means simple real-time models constructed in laboratory environment.
