Inventory - MAC Address

[Rene2mt]

Constraint Task

Consistent with issue #813, this constraint focuses on ensuring MAC address information is provided when applicable via the "mac-address" prop for inventory item.

Intended Outcome

MAC address is an optional property, but SHOULD be present when the inventory item has a MAC address.

There may be more than one MAC addresses if the inventory item has multiple network interfaces.

Syntax Type

This is optional core OSCAL syntax.

Allowed Values

There are no relevant allowed values.

Metapath(s) to Content

//inventory-item/prop[@name='mac-address']

regex = “^([0-9A-Fa-f]{2}[:-]){5}([0-9A-Fa-f]{2})|([0-9a-fA-F]{4}\\.[0-9a-fA-F]{4}\\.[0-9a-fA-F]{4})$”;

@Rene2mt Since this constraint is using regex to enforce a format, should we consider making this an error instead of a warning? If the MAC address prop itself is optional, I think when it is used it must have the correct format.
