      Transport of Real-time Inter-network Defense (RID) Messages
                             over HTTP/TLS

Abstract

   The Incident Object Description Exchange Format (IODEF) defines a
   common XML format for document exchange, and Real-time Inter-network
   Defense (RID) defines extensions to IODEF intended for the
   cooperative handling of security incidents within consortia of
   network operators and enterprises.  This document specifies an
   application-layer protocol for RID based upon the passing of RID
   messages over HTTP/TLS.

1.  Introduction

   The Incident Object Description Exchange Format (IODEF) [RFC5070]
   describes an XML document format for the purpose of exchanging data
   between Computer Security Incident Response Teams (CSIRTs) or those
   responsible for security incident handling for service providers
   (SPs).  The defined document format provides a simple way for CSIRTs
   to exchange data in a way which can be easily parsed.

   IODEF defines a message format, not a protocol, as the sharing of
   messages is assumed to be out of scope in order to allow CSIRTs to
   exchange and store messages in a way most suited to their established
   incident-handling processes.  However, Real-time Inter-network
   Defense (RID) [RFC6545] does require a specification of a protocol to
   ensure interoperability among members in a RID consortium.  This
   document specifies the transport of RID messages within HTTP
   [RFC2616] Request and Response messages over TLS [RFC5246] (herein,
   HTTP/TLS).  Note that any IODEF message may also be transported using
   this mechanism, by sending it as a RID Report message.

1.1.  Changes from RFC 6046

   This document contains the following changes with respect to its
   predecessor [RFC6046]:

   o  The status of the document is Standards Track.

   o  The document is updated to refer to the updated RID specification,
      [RFC6545], where appropriate.

   o  Language regarding the use of HTTP/1.1 and TCP ports for RID
      transport is clarified.

   o  The RID-Callback-Token entity header field is added to allow
      matching of RID replies during callback, independent of the
      content of the underlying RID message.

   o  The minimum required version of TLS is upgraded to 1.1, and the
      minimum recommended version to 1.2.

   o  Language regarding PKI for RID over HTTPS is clarified, and
      updated to refer to [RFC6125].

   This document obsoletes [RFC6046] and moves it to Historic status.
