Transport of Real-time Inter-network Defense (RID) Messages
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.

RFC 6546 RID Transport April 2012
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
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.
