The Federal Communications Commission’s (FCC or Commission) Public Safety and Homeland Security Bureau is seeking comment on the implementation and effectiveness of the Communications Security, Reliability and Interoperability Council (CSRIC III)’s recommendations for Internet service providers (ISPs) to combat major cybersecurity threats such as botnet attacks, domain name fraud, and Internet route hijacking. CSRIC III’s recommendations included voluntary measures in these those three areas, including: an Anti-Bot Code of Conduct to mitigate the proliferation of distributed denial of service (DDoS) attacks, four steps to better secure the Domain Name System (DNS) through incremental implementation of DNSSEC, and steps to strengthen the security of the Internet’s inter-domain routing infrastructure. CSRIC III also recommended that the FCC encourage ISPs to implement source-address filtering to prevent attackers from spoofing Internet protocol (IP) addresses to launch DDoS attacks. The Bureau seeks public comment on the implementation status and effectiveness of these voluntary recommendations, or alternatives, by ISPs and other members of the Internet community. Comments are due September 26, 2014.
