  • Illuminating the Higher Layers of Mobile Networks
    Beyond the Radio: Illuminating the Higher Layers of Mobile Networks Narseo Vallina-Rodriguez§, Srikanth Sundaresan§, Christian Kreibich§*, Nicholas Weaver§ⱡ, and Vern Paxson§ⱡ TR-14-003 December 2014 Abstract Cellular network performance is often viewed as primarily dominated by the radio technology. However, reality proves more complex: mobile operators deploy and configure their networks in different ways, and sometimes establish network sharing agreements with other mobile carriers. Moreover, regulators have encouraged newer operational models such as Mobile Virtual Network Operators (MVNOs) to promote competition. In this paper we draw upon data collected by the ICSI Netalyzr app for Android to develop a characterization of how operational decisions, such as network configurations, business models, and relationships between operators introduce diversity in service quality and affect user security and privacy. We delve in detail beyond the radio link and into network configuration and business relationships in six countries. We identify the widespread use of transparent middleboxes such as HTTP and DNS proxies, analyzing how they actively modify user traffic, compromise user privacy, and potentially undermine user security. In addition, we identify network sharing agreements between operators, highlighting the implications of roaming and characterizing the properties of MVNOs, including that a majority are simply rebranded versions of major operators. More broadly, our findings highlight the importance of considering higher-layer relationships

However, the security criteria telecommunication networks. The telecommunications envisioned 30 years ago, when the standard was designed, industry uses a combination of 2G (GSM), 3G (Universal Mobile are no longer sufficient to ensure the security and privacy of Telecommunications Service-UMTS) and 4G (Long Term the users. Furthermore, even with the newest fourth Evolution-LTE) systems to access communication worldwide. generation (4G) cellular technologies starting to be However telecommunications industry keeps a high deployed, these networks could never achieve strong percentage of their deployed infrastructure using GSM security guarantees because the MNOs keep backwards technologies. GSM offers worldwide roaming and compatibility given the huge amount of GSM subscribers. interconnection with any available GSM network. Users are Recent research has shown that mobile devices data can be expected to be aware of the possible security threats. This used as an effective way to track individuals [2]. This work highlights weaknesses and issues in the GSM standard, presents a problem related to users’ privacy, as their and presents an informed approach to help audit GSM location allows the carriers to profile and track their networks for vulnerabilities.
