Securing DOCSIS Cable Networks (2002)

By Annie Phan, Cisco Systems

It is a fact that within all shared networks; there is inherent security risk. Allowing multiple entities access to shared network resources carries with it a number of known vulnerabilities. DOCSIS cable IP networks, because they are based on a shared network architecture are prone to violation of data privacy, theft-of-service attacks, and denial-of-service attacks. However, cable IP networks can be easily protected from these attacks and can supply a level of security roughly equivalent to that of an unshared access medium.

The intended audience for this paper is cable operators who are deploying or wish to deploy data over their networks today.
