Cable Already Active on Traffic Routing Security, FCC Told

The cable industry has been aggressive in Resource Public Key Infrastructure (RPKI) deployments, and internet traffic routing is more secure, due to industry and international standards and security practices by major ISPs, cable representatives told FCC Public Safety and Homeland Security Bureau Chief Debra Jordan and aide to Commissioner Brendan Carr in separate ex partes, per docket 22-90 Friday. NCTA, Comcast, Charter and Cox said that when measuring the volume of residential broadband traffic on RPKI-valid routes, nearly 60% of U.S. internet traffic terminated at RPKI-protected IP addresses. That's due to ISPs completing RPKI deployments that account for a large percentage of residential broadband internet traffic, and most of this traffic is destined to large content and cloud providers that have also completed RPKI deployments, they said. As well as RPKI for both signing and validating routes, major cable ISPs have taken such routing security steps as prefix filtering, source address validation and use of anti-distributed denial of service attack, they said.
