Protocols, Smart Polling, and Arc

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

  • Introduced support for the import for Mitsubishi Electric GXWorks3 (iQ-R series) project / configuration files.
  • Devices using the DICOM protocol can now be accurately identified and classified as assets, improving visibility in medical environments.
  • The graph visualization in alert details has been improved to maintain consistency even in dynamic network environments.
  • Discovery can now be configured from a dedicated menu under Settings. The user can now also select the particular strategies to enable.
  • Introduced a configuration to choose the asset field extraction strategy for the name of an asset. More details are available in the documentation.
  • An improved message is now shown when downloading an Arc Microsoft Software Installer (MSI) bundle, explaining how to perform the installation.
  • The Assets page now displays a richer set of Hardware components details, offering improved visibility and organization.
  • Nozomi Networks Operating System (N2OS) now uses spanning tree protocol (STP) information to improve the grouping of nodes into assets.
  • Improved the robustness of variables extraction for the message queuing telemetry transport (MQTT) protocol.
  • The Data to be Collected dropdown has been removed from the simple network management protocol (SNMP) strategy dialog. With Smart Polling, all available asset details are now collected automatically.
  • The Hardware components tab for Windows machines hosting Arc has been improved with filtering capabilities.
  • Arc functionalities are now available either as a complete package or through two separate licenses:
    • Arc Endpoint: covers all local detections on the endpoint
    • Arc Sensor: includes network sensor features such as Traffic Monitoring, Discovery, and Smart Polling
    Note:
    A separate license is still required for Smart Polling. This license split applies only to standard Arc, not Arc Embedded.
  • Addressed an issue that lead to identifying unicast nodes as broadcast nodes.
  • Smart Polling now allows users to configure custom object identifier (OID)s and map them to specific asset information during SNMP polling, without requiring imported management information base (MIB)s. See the documentation for details.
  • N2OS detects seamless message protocol (SLMP) protocol traffic on ports [4096 - 33170] by default. Users can now configure additional destination ports using the probe protocol slmp ports tcp/<port_number> command.
  • The Berkeley Packet Filter (BPF) filter associated with a node is now correctly updated when the node internet protocol (IP) is updated, in presence of IP renaming due to dynamic networks.
  • In dynamic networks, BPF filters are now properly updated when a node’s IP address is renamed or modified.
  • Inactive nodes with manually edited fields or details from file-imports are now ignored by the garbage collector unless explicitly included by entering the vi gc keep_imported_nodes 0 command in the configuration file.
  • Rockwell programmable logic controller (PLC)s now generate dedicated alerts when the physical key position changes, improving visibility into operational state transitions.
