Last Call Review of draft-ietf-eman-requirements-10
review-ietf-eman-requirements-10-secdir-lc-nystrom-2013-01-25-00

I have reviewed this document as part of the security directorate's
ongoing effort to review all IETF documents being processed by the
IESG.  These comments were written primarily for the benefit of the
security area directors. Document editors and WG chairs should treat
these comments just like any other last call comments.

This standards-track document describes requirements on standards for managing
power entities over networks.

 As stated in the Security Considerations section, controlling power state and
 power supply of networked energy entities are highly sensitive actions and
 thus authorization, privacy etc. may be required. Similarly, the date provided
 by those entities will often require integrity and sometimes authenticity. The
 document may gain by also making clear the potential need for the energy
 entities to identify, authenticate and authorize the entities requesting
 access to power data. I would suggest to add some text around this - because I
 assume some requirements on standards will be present for that.
