The IESG has approved the following document: - 'IODEF-extension for structured cybersecurity information' (draft-ietf-mile-sci-13.txt) as Proposed Standard This document is the product of the Managed Incident Lightweight Exchange Working Group. The IESG contact persons are Sean Turner and Stephen Farrell. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-mile-sci/ Technical Summary The document extends the Incident Object Description Exchange Format (IODEF) defined in RFC 5070 [RFC5070] to exchange enriched cybersecurity information . It provides the capability of embedding structured information, such as identifier- and XML-based information. It defines an IANA registry of external schemas that can be referenced from IODEF documents. Working Group Summary and Document Quality The document received extensive review from the working group, which led to significant changes in the document. Earlier versions of the document had significant potential IPR issues (references to trademarked schema names) as well as reference issues (normative references to non-standards documents); these have all been resolved satisfactorily by moving these references to an IANA registry of SCI specifications, and providing for long-term references to the MTI schema, MMDEF. Personnel Brian Trammell is the doc shepherd. Sean Turner is the responsible AD.
