Protocols, Smart Polling, and Arc

A list of the improvements for Protocols, Smart Polling and Arc that have been introduced in this release.

The Arc Deployment page now supports One-shot mode enabling single-execution endpoint and network analysis and returning target endpoint machines to their original state afterwards.
Improved support of Yokogawa Vnet/ip traffic by adding asset serial number extraction.
Extended the support for Yokogawa project files. More information is now collected, including serial number and multiple internet protocol (IP) allocations.
Yokogawa imported information extracted by project files is now correctly tagged with source import.
Users can now access an Arc's Status page and configure Arc in bulk from the user interface (UI) of an on-premise sensor.
Nozomi Networks Operating System (N2OS) now supports tagging and function code extraction for the Hitachi Rails Genisys protocol.
The Yokogawa Vnet/IP protocol now supports extraction of variables requested by name.
A package file (.pkg) file is now available from the Sensors page for installing Arc under macOS. The existing ZIP archives for macOS are still available, allowing for One-shot and Offline executions.
The nodes_count field of the sp_executions query source is now deprecated. In a future version of N2OS it will be removed.
Addressed an issue that incorrectly confirmed invalid media access control (MAC) addresses coming from forged offline traffic.
Added support for extracting asset information from GRE ERSPAN Type 3 encapsulated traffic.
Broadcast IP addresses no longer generate assets.
Improved sorting to show properties and hardware components in the asset view.
Introduced the new field source Discovery for information obtained using the new feature.
Smart Polling and Discovery can now be enabled or disabled independently from the Arc deployment settings.
Improve the resiliency of the intrusion detection system (IDS) against unknown EtherTypes.
