Collaboration between competing mobile network operators to improve CIIP

Abstract

Mobile Network Operators (MNOs) deploy a vital part of today's Critical Information Infrastructures (CII). Protection of these CIIs shall ensure operational continuity despite of the potential loss of system integrity and malware attacks. Sharing information about security related incidents allows MNOs to better react to attacks and anomalies, and to mitigate the impact of the observed phenomena. The fear to risk its reputation may hinder an MNO to share information that could help other MNOs to improve their protection and assure operational continuity. The contributions of this paper are technical solutions for collaboration between competing MNOs, which prevent loss of reputation and thus improve the acceptance to share information. © 2013 Springer-Verlag.
