IEEE 1686 5.2.3: IED main security functions subject to authorization

The IED's main security functions are each placed under the authorization mechanism so that each can be restricted by level or role. The 2013 edition, which Table 1 says is now 5.2.3, lists seven: (a) viewing data; (b) viewing configuration settings; (c) forcing values; (d) changing the configuration; (e) changing firmware; (f) managing IDs and passwords or RBAC; (g) the audit trail. A conformance declaration answers each item separately.
