nodes

A list of nodes, where a node is an L2 or L3 or other entity able to speak some protocol.

appliance_host The hostname of the sensor where this entity has been observed
label Name of the node
id Primary key of this query source
ip internet protocol (IP) address of the node. It can be either IPv4, IPv6 or empty (in case of L2 node)
mac_address media access control (MAC) address of the node. It can be missing in some situations (serial nodes)
mac_address:info This is a metadata field about the mac_address field.
  • protocol_source - is the cause of the latest mac_address:info change
  • likelihood - a value between 0.1 and 1.0 where 1.0 represents the maximum likelihood that the MAC address is the native one from the node.
  • likelihood_level - level of confidence regarding whether the MAC address is the native one from the node, or it is one routed/substituted by the network. Values:
    • unconfirmed (no information is available)
    • likely (some information indicates it can be native)
    • confirmed (it is definitely native)
  • source - indicates where the information comes from:
    • manual: information that is manually added from the configuration
    • import: imported information
    • passive: information from Deep Packet Inspection
    • asset-kb: information from Asset Intelligence
    • smart-polling: information from Smart Polling
  • granularity - is the level of detail of the information. Values:
    • manual-or-import: information manually added or imported
    • complete: detailed information has been extracted.
    • partial: detailed, but still not complete.
    • generic: a family/generic value has been found, but is not detailed.
    • unknown
  • confidence - measures the confidence that the information is the one published. Values:
    • manual-or-import: information manually added or imported, therefore the highest confidence
    • high
    • good
    • low
    • unknown
mac_vendor MAC address vendor. Is not empty when the MAC address is present and the corresponding Vendor name is known.
subnet The subnet to which this node belongs, if any.
vlan_id The virtual local area network (VLAN) identifier (ID) of the node. It can be absent if the traffic to/from the node is not VLAN-tagged.
vlan_id:info This is a metadata field about the vlan_id field.
zone The zone name to which this node belongs to
level The purdue-model level of the node
type The type of the node
type:info This is a metadata field about the type field.
os Operating System of the node, if available. This field is not present when the firmware_version is available.
vendor Vendor of the node
vendor:info This is a metadata field about the vendor field.
product_name The product name of the node
product_name:info This is a metadata field about the product_name field.
firmware_version The firmware version of the node. The field is not present when the os field is available.
firmware_version:info This is a metadata field about the firmware_version field.
serial_number The serial number of the node
serial_number:info This is a metadata field about the serial_number field.
is_broadcast True if this is not a real node but a broadcast or multicast entry
is_public True if this not a local node but an outside, public IP address.
reputation This can be good or bad depending on information coming from STIX indicators
is_confirmed This is true for nodes that are confirmed to exist. Non-existing targets of port scans for instance are not confirmed
is_compromised This is true for nodes that have been recognised as compromised according to threat indicators
is_learned This is true for nodes that were observed during the learning phase
is_fully_learned This is true for nodes that were observed also during the learning phase and which properties are not changed since then
is_disabled This is true for nodes that are hidden from graphs because too noisy
roles The set of application-level roles of the node. Differently from the type, these are behaviors.
links The set of links to which this node is related
links_count The total number of links from and to this node
protocols The unique protocols used from and to this node
created_at Timestamp in epoch milliseconds when this node was first observed
first_activity_time Timestamp in epoch milliseconds when this node send a packet for the first time
last_activity_time Timestamp in epoch milliseconds when this node send a packet for the last time
