IEC 62351 - Power Systems Communication Security 90-2:5: Part 90-2, clauses 4 to 6: monitoring and auditing requirements and the encrypted channels of IEC 62351 (utility and vendor use cases, the recorded-encrypted-call analogy, parts 3, 4 and 6)

The need for inspection is drawn from utility and vendor monitoring and auditing use cases (with the recording of encrypted voice calls as an analogous problem) and set against the encrypted or authenticated channels the series creates under part 3 (TLS), part 4 (MMS) and part 6 (IEC 61850).
