      Attacks and Counter Measures in 2.5G and 3G Cellular IP Networks
    ------------------------------------------------------------------------

    SUMMARY

    Linked below is a white paper discussing security risks to the 2.5G and
    3.0G cellular networks. The paper focus is weaknesses in GTP (GPRS
    Tunneling Protocol), and an assessment of the solution provided by Check
    Point FireWall-1 GX.

    DETAILS

    Abstract:
    2.5G and 3.0G cellular technologies are here to stay. This white paper
    assesses the issues still facing the industry since the "
    <http://www.atstake.com/research/reports/acrobat/atstake_gprs_security.pdf> GPRS Wireless Security: Not Ready for Primetime" paper was published in June 2002. GTP (GPRS Tunneling Protocol) is now widely deployed in a majority of 2.5G and 3.0G cellular networks, and this paper reviews some of the potential attacks against the GTP protocol and the possible effects this will have on cellular providers. It also reviews some of the architectural alternatives that providers can consider. This paper also presents the results of the @stake assessment of the Check Point FireWall-1 GX solution.
