(Feel free to cut this introductory paragraph, however.) Please refer to https://www.ietf.org/iesg/statement/discuss-criteria.html for more information about DISCUSS and COMMENT positions. The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-6lo-plc/ ---------------------------------------------------------------------- DISCUSS: ---------------------------------------------------------------------- ** Section 8. A few additional threats should be mentioned. Note that a robust treatment is not needed here (and likely not possible due to the generality of this document). However, they should be acknowledged. -- This section mentions both availability (DoS) and confidentiality (eavesdropping) concerns. Thank you. Wouldn’t there also be the possibility of significant integrity risks given that possible actuators or sensors being controlled? Note if the referenced link layer security mechanisms would be useful. -- Figures 5 – 7 seems to present architectures which connects operational technology to the Internet via the PANC. However, this section doesn’t acknowledgement of that risk outright or by citation. ** Section 8. Per “Thus link layer security mechanisms are designed in the PLC technologies mentioned in this document”, which specific mechanisms were being cited is not clear. Is their use required or are they use case dependent? ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- Thank you to Robert Sparks for the SECDIR review. ** Section 6. Per “The onboard status of the devices and the topology of the PLC network can be visualized via the gateway”, this is the first the architectural element of a “gateway” is mentioned. What does it mean to “visualize via the gateway”? ** Section 6. Per “The recently-formed iotops WG in IETF is aming to design more features for the management of IOT networks”, I don’t follow the intent of this sentence as IOTOPS is not chartered for new protocol work (only requirements and operational practices). ** Editorial nits -- Section 1.
