Article Summary

Axonius-provided Axonius Network Discovery adapter, performing standardized network discovery.
The Axonius Network Discovery adapter scans your network and discovers the assets connected to the network. This is an active scan and could be flagged by security systems as a possible penetration. The Axonius Network Discovery adapter runs on every discovery cycle and at any other custom discovery cycle configured. Information fetched by this adapter can include the following parameters, depending on the asset.

  • IP address
  • Host name
  • OS
  • Open ports and their common use
  • MAC address

This adapter fetches the following types of assets:

  • Devices

Parameters for Customer-hosted (on-premise / private cloud)

  1. Use Auto-discover Subnet - Select this option to use the auto-discover IP range for the network discovery. This is a subnet of the Axonius machine (based on the IP address of the Axonius machine).
  2. Additional Network Subnets - Set an IP range to use. When working with customer-hosted machines this is an optional field. The IP range should be input in subnet style for example 10.0.0.0/24. Multiple ranges are supported using a delimiter.
  3. Exclude Network Subnets - Set an IP range to exclude. The IP range should be input in subnet style for example 10.0.0.0/24. Multiple ranges are supported using a delimiter.
  4. Ports to scan - Set the number of ports to scan, either 'Top 100' or 'Top 1000'.
  5. Hosts to exclude from scan - Enter a comma separated list of hosts to exclude from the scan.
  6. Ports to exclude from scan - Enter a comma separated lists of ports to exclude from the scan.
