Managed Incident Lightweight Exchange (mile)

Charter for Working Group

The Managed Incident Lightweight Exchange (MILE) working group will
develop standards and extensions for the purpose of improving incident
information sharing and handling capabilities based on the work
developed in the IETF Extended INCident Handling (INCH) working group.
The Incident Object Description Exchange Format (IODEF) in RFC5070 and
Real-time Inter-network Defense (RID) in RFC6045 were developed in the
INCH working group by international Computer Security Incident Response
Teams (CSIRTs) and industry to meet the needs of a global community
interested in sharing, handling, and exchanging incident information.
The extensions and guidance created by the MILE working group assists
with the daily operations of CSIRTs at an organization, service
provider, law enforcement, and at the country level. The application of
IODEF and RID to interdomain incident information cooperative exchange
and sharing has recently expanded and the need for extensions has become
more important. Efforts continue to deploy IODEF and RID, as well as to
extend them to support specific use cases covering reporting and
mitigation of current threats such as anti-phishing extensions.

An incident could be a benign configuration issue, IT incident, an
infraction to a service level agreement (SLA), a system compromise,
socially engineered phishing attack, or a denial-of-service (DoS)
attack, etc. When an incident is detected, the response may include
simply filing a report, notification to the source of the incident, a
request to a third party for resolution/mitigation, or a request to
locate the source. IODEF defines a data representation that provides a
standard format for sharing information commonly exchanged about
computer security incidents. RID enables the secure exchange of
incident related information in an IODEF format providing options for
security, privacy, and policy setting.

MILE leverages collaboration and sharing experiences with the work
developed in the INCH working group which includes the data model
detailed in the IODEF, existing extensions to the IODEF for
Anti-phishing (RFC5901), and RID (RFC6045, RFC6046) for the secure
exchange of information. MILE will also leverage the experience gained
in using IODEF and RID in operational contexts. Related work, drafted
outside of INCH will also be reviewed and includes RFC5941, Sharing
Transaction Fraud Data.

The MILE working group provides coordination for these various extension
efforts to improve the capabilities for exchanging incident information.
MILE has several objectives with the first being a description a
subset of IODEF focused on ease of deployment and applicability to
current information security data sharing use cases. MILE also
describes a generalization of RID for secure exchange of other
security-relevant XML formats. MILE produces additional guidance needed
for the successful exchange of incident information for new use cases
according to policy, security, and privacy requirements. Finally, MILE
produces a document template with guidance for defining IODEF extensions
to be followed when producing extensions to IODEF as appropriate, for:

* labeling incident reports with data protection, data retention, and
other policies, regulations, and
laws restricting the handling of those reports
* referencing structured security information from within incident
reports
* reporting forensic data generated during an incident investigation
(computer or accounting)

The WG will produce the following:

* An informational document on IODEF Guidance.
* A Standards Track document specifying the Real-time Inter-network
Defense (RID).
* A Standards Track document specifying the transport for RID.
* An informational template for extensions to IODEF.
* A Standards Track document for IODEF Extensions in IANA XML Registry.
* A Standards Track document for IODEF Extension to support
structured cybersecurity information.
* A Standards Track document for Labeling for data protection,
retention, policies, and regulations.
* A Standards Track document for GRC Report Exchange.
* A Standards Track document for IODEF Extension to support forensics.
