The IETF’s NEA Working Group is (among other things) standardizing a set of “PA-TNC attributes” for use during NAC health checks. These standard attributes will be implemented in many network endpoints (laptops, desktops, printers, etc.) so that a NAC server can query an endpoint and obtain information about its health in a standard way. The tricky part is deciding which attributes are important enough to be in the first standard and which attributes can be left to future standards or vendor extensions.
I bet you have some ideas on this topic. Review the current draft list of attributes (below) and post your comments. I’ll bring them back to the NEA WG. Thanks!
A standard set of components are defined and then a standard set of attributes that describe aspects of those components. This avoids the need to define separate attributes for “OS Version”, “AV Version”, etc. Of course, some devices won’t implement all these components and attributes. No Anti-Virus on my printer (yet!).
Attributes: Product Information (vendor, name), Numeric Version, String Version, Operational Status (operational?, problems detected?, last time run), Port Filter List (for Host Firewall), Installed Packages (name, version)
