 remotely, then a dataset is specified in 1588-2019 and, with that, datasets clearly become an information model for management. However, this approach of using management messages without any comprehensive system of built-in security can expose PTP clocks to numerous types of attacks from within the network. And so, most of the equipment vendors either do not recommend these management messages or have disabled them. As previously mentioned, they are not supported in many profiles, including the tele- com profiles. However, designing an accurate timing network is not enough if we cannot monitor and manage it; hence, IEEE and IETF have defined other mechanisms that provide detail state and performance statistics of the timing device. 12.4.1 SNMP The history of network operations has shown that SNMP is a good mechanism for fault handling (sending SNMP traps to a centralized collector for fault isolation) and monitoring of the devices (for example, enabling the retrieval of performance data). With the increasing adoption of PTP for timing distribution, clearly an SNMP Management Information Base (MIB) was needed to apply similar management techniques to timing. The IETF proposed a standard, "Precision Time Protocol Version 2 (PTPv2) Management Informa- tion Base," in RFC 8173. To be fair, this proposed standard is dated June 2017 and has not been up- dated since then, and it doesn't apply to PTPv1. From the point of view of the telecom profiles, RFC 8173 only considers the G.8265.1 telecom profile for frequency, and the rest are out of scope. Much like the Yet Another Next Generation (YANG) models, this SNMP MIB focused on man- aging the standard PTP data elements, which has some shortcoming in the 1588-2008 edition. There is also a project at the IEEE to draft an amendment to 1588-2019 to define a MIB to support the new version. See the following section on the YANG developments for more details on both these topics. Note that there is not a currently defined MIB for the ITU-T G.8275.1 profile, which makes SNMP wh
