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 a
transport protocol for RID based upon the passing of RID messages
over HTTP/TLS (Transport Layer Security).

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 network providers
(NPs). The defined document format provides an easy way for CSIRTs
to exchange data in a way that can be easily parsed.
IODEF defines a message format, not a transport 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) [RFC6045] does require a specification of
a transport 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
transported over Transport Layer Security (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.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].
3. Transmission of RID Messages over HTTP/TLS
This section specifies the details of the transport of RID messages
over HTTP/TLS. In this arrangement, each RID server is both an HTTP/
TLS server and an HTTP/TLS client. When a RID message must be sent,
the sending RID system connects to the receiving RID system and sends
Moriarty & Trammell Informational [Page 2]RFC 6046 RID Transport November 2010
the message, optionally receiving a message in reply. All RID
systems MUST be prepared to accept HTTP/TLS connections from any RID
peer with which it communicates, in order to support callback for
delayed replies (see below).
BCP 56 [RFC3205] contains a number of important considerations when
using HTTP for application protocols. These include the size of the
