                 Real-time Inter-network Defense (RID)

Abstract

   Network security incidents, such as system compromises, worms,
   viruses, phishing incidents, and denial of service, typically result
   in the loss of service, data, and resources both human and system.
   Network providers and Computer Security Incident Response Teams need
   to be equipped and ready to assist in communicating and tracing
   security incidents with tools and procedures in place before the
   occurrence of an attack.  Real-time Inter-network Defense (RID)
   outlines a proactive inter-network communication method to facilitate
   sharing incident handling data while integrating existing detection,
   tracing, source identification, and mitigation mechanisms for a
   complete incident handling solution.  Combining these capabilities in
   a communication system provides a way to achieve higher security
   levels on networks.  Policy guidelines for handling incidents are
   recommended and can be agreed upon by a consortium using the security
   recommendations and considerations.

   RID has found use within the international research communities, but
   has not been widely adopted in other sectors.  This publication
   provides the specification to those communities that have adopted it,
   and communities currently considering solutions for real-time inter-
   network defense.  The specification may also accelerate development
   of solutions where different transports or message formats are
   required by leveraging the data elements and structures specified
   here.
