1. Introduction
The Internet Architecture Board (IAB) holds occasional workshops
designed to consider long-term issues and strategies for the
Internet, and to suggest future directions for the Internet
architecture. This long-term planning function of the IAB is
complementary to the ongoing engineering efforts performed by working
groups of the Internet Engineering Task Force (IETF), under the
leadership of the Internet Engineering Steering Group (IESG) and area
directorates.
The Internet Architecture Board (IAB) and the Internet Society (ISOC)
hosted a day-long Coordinating Attack Response at Internet Scale
(CARIS) workshop on 18 June 2015 in coordination with the Forum for
Incident Response and Security Teams (FIRST) Conference in Berlin.
The workshop included members of the FIRST community, attack response
working group representatives, network and security operators,
Regional Internet Registry (RIR) representatives, researchers,
vendors, and representatives from standardization communities. The
key goals of the workshop were to improve mutual awareness,
understanding, and coordination among the diverse participating
