1.  Problem

   Threat Actors and Intrusion Sets are advancing at an increasing rate
   relative to an organization's ability to defend against and respond
   to cyber attacks.  In addition, it is common that defenders need to
   manually identify and process prevention, mitigation, and remediation
   steps in order to protect their systems, networks, data, and users.
   There is also currently no standard means to easily and dynamically
   share proposed prevention, mitigation, or remediation steps and the
   operational experience gained from these attacks or their associated
   successful responses among a trusted set of organizations.

   Due to the increasing sophistication and amplitude of cyber attacks
   the need for a secure collaborative set of systems providing
   coordinated detection and response across hosts, networks, and
   security infrastructure has raised significantly.  This solution is
   necessary to effectively respond to threats in machine relevant time.
   While some attacks may be well known to certain security experts and
   researchers they are often not documented in a way that would enable
   automated prevention, mitigation, or remediation.

   Key to this coordinated cyber attack response is a coordinated threat
   response including a standard information model; a set of functional
   capabilities, associated interfaces, and protocols.  These key
   requirements would be defined in each of the system components across
   host; network and security infrastructure to ensure that each system
   can work together in a coordinated manner.

2.  Working Group

   To enable efficient collaboration and facilitate the rapid sharing of
   preventative, mitigative, and remediative actions this working group
   will focus on defining the set of technologies (protocols,
   interfaces, functional capabilities, and information model) required
   to detect, prevent, mitigate, and remediate threats.  This solution
   will also define the machine-readable actions to enable an action-
   oriented defensive system.  This effort will focus on providing the
   functionality requirements for each system that would participate in
   a coordinated threat response; the interfaces they should support
   including the transport mechanism used and finally the information
