The telecommunications networks are one of our most important critical infrastructure assets. In fact all of the other critical infrastructure domains are dependent upon the telecommunications critical infrastructure for operation for example ICS\SCADA. In this talk we will discuss a quick overview of telecommunication architectures and operations for border gateway protocol (BGP) services with references to the recent BGP prefix hijacking attacks. The discussion will then pivot to how Multi-protocol Label Switch (MPLS) networks may be attacked in telecommunications networks. Could it be that the MPLS networks are being attacked similar to BGP? How would someone go about targeting MPLS networks? The MPLS discussion will provide an overview of MPLS VPN’s and MPLS traffic engineering architectures and operations including packet captures of label traffic for reference. Attack vectors for targeting MPLS networks will be addressed in addition to a couple new ideas for gathering intel from MPLS networks. Recommendations for monitoring and securing BGP and MPLS networks will be discussed as well.
