IODEF-extension to support structured cybersecurity information
draft-ietf-mile-sci-06.txt
Abstract
This document extends the Incident Object Description Exchange Format
(IODEF) defined in RFC 5070 [RFC5070] to exchange enriched
cybersecurity information among cybersecurity entities and facilitate
their operations. It provides the capability of embedding structured
information, such as identifier- and XML-based information.
