Signaling-Oriented DoS Attacks in UMTS Networks

چکیده
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.

DoS attacks exploiting signaling in UMTS and IMS
The Universal Mobile Telecommunication Standard (UMTS) is continuously evolving to meet the growing demand of modern mobile and Internet applications for high capacity and advanced features in security and quality of service. Although admittedly enhanced in terms of security when compared to 2G systems, UMTS still has weaknesses that can lead to security incidents. In this paper we investigate ...
متن کاملOn the detection of signaling DoS attacks on 3G/WiMax wireless networks
Third Generation (3G) wireless networks based on the CDMA2000 and UMTS standards are now increasingly being deployed throughout the world. Because of their complex signaling and relatively limited bandwidth, these 3G networks are generally more vulnerable than their wireline counterparts, thus making them fertile ground for new attacks. In this paper, we identify and study a novel Denial of Ser...
متن کاملToward Actively Defending from Dos Attacks in Umts- Wlan
A wireless network is more vulnerable to denial of service (DoS) attacks than a wired one. In this paper we propose a new DoS defense scheme toward actively resisting DoS attacks. A mobile terminal generates an authorized anonymous ID (AAI) using its true ID, and assigns its true ID with the produced AAI. Using an AAI, a legitimate mobile terminal will be authenticated by the wireless network, ...
متن کاملA Mechanism for Detecting and Identifying DoS attack in VANET
VANET (Vehicular Ad-hoc Network) which is a hy- brid network (combination of infrastructure and infra- structure-less networks) is an emergent technology with promising future as well as great challenges especially in security. By the other hand this type of network is very sensible to safety problem. This paper focuses on a new mechanism for DoS (denial of service) attacks on the physical and ...
