Abstract

The Universal Mobile Telecommunication Standard (UMTS) is the Third Generation (3G) mobile technology with the widest public acceptance. Although, enhanced in matters of security, comparing to its predecessor i.e., the GSM, it still has vulnerabilities that can lead to security breach. In this paper we investigate the vulnerabilities of the UMTS architecture that can be exploited by a malicious entity to launch Denial of Service (DoS) attacks. We examine the methodologies that an attacker would possibly follow, as well as the possible outcome of such class of attacks. We also give some suggestions that would provide greater tolerance to the system against DoS attacks.
