Query: CSAI: Open-Source Cellular Radio Access Network Security Analysis
  Instrument   This paper presents our methodology and toolbox that allows analyzing the
radio access network security of laboratory and commercial 4G and future 5G
cellular networks. We leverage a free open-source software suite that
implements the LTE UE and eNB enabling real-time signaling using software radio
peripherals. We modify the UE software processing stack to act as an LTE packet
collection and examination tool. This is possible because of the openness of
the 3GPP specifications. Hence, we are able to receive and decode LTE downlink
messages for the purpose of analyzing potential security problems of the
standard. This paper shows how to rapidly prototype LTE tools and build a
software-defined radio access network (RAN) analysis instrument for research
and education. Using CSAI, the Cellular RAN Security Analysis Instrument, a
researcher can analyze broadcast and paging messages of cellular networks. CSAI
is also able to test networks to aid in the identification of vulnerabilities
and verify functionality post-remediation. Additionally, we found that it can
crash an eNB which motivates equivalent analyses of commercial network
equipment and its robustness against denial of service attacks.
