By Matt Tooley, NCTA, Matt Carothers, Cox Communications, Michael Glenn, CableLabs, Michael O’Reirdan, Comcast, Chris Roosenraad, Time-Warner Cable, and Bill Sweeney, Comcast

The challenges of protecting networks from cyber threats have evolved from computer viruses and spam plaguing desktop computers to advanced persistent threats and cloud-based multi-gigabit distributed denial of service attacks. This paper examines the evolution of the attack vectors to the DOCSIS™ networks and their associated attack surfaces. It then surveys the tools that are in the DOCSIS standards today that can be used to mitigate the threat vectors. Further it examines the evolution of cable networks technologies such as software defined networking and big data. Finally it then proposes methods to integrate software-defined networks and big data to improve the overall robustness and security of the cable networks.
