Re: [sacm] 答复: new drafts about network infrastructure device's security baseline:

Dave's recollection regarding "endpoint" in SACM is correct - it's an old
discussion that comes up from time to time, but because network devices are
often addressable by IP, they're considered in the context of their
management an endpoint. The charter could have been clearer, perhaps, and
as we work toward a new charter (chairs will have something to the list
very soon) the working group may choose to be more specific.

Kind regards,

Adam

This view is also reflected in the SACM terminology, which states “To further clarify the [RFC5209 <https://tools.ietf.org/html/rfc5209>] definition, an endpoint is any
