Integrate Nmap with Google SecOps

This document explains how to integrate Nmap with Google Security Operations.

Integration version: 1.0

Integration parameters

The Nmap integration requires no parameters.

Actions

For more information about actions, see Respond to pending actions from Your Workdesk and Perform a manual action.

Ping

Use the Ping action to test the connectivity to Nmap.

This action doesn't run on Google SecOps entities.

Action inputs

None.

Action outputs

The Ping action provides the following outputs:

Action output type Availability
Case wall attachment Not available
Case wall link Not available
Case wall table Not available
Enrichment table Not available
JSON result Not available
Output messages Available
Script result Available
Output messages

The Ping action can return the following output messages:

Output message Message description

Successfully connected to the Nmap server with the provided connection parameters!

 The action succeeded.
Failed to connect to the Nmap server! Error is ERROR_REASON

The action failed.

Check the connection to the server, input parameters, or credentials.
Script result

The following table lists the value for the script result output when using the Ping action:

Script result name Value
is_success True or False

Scan Entities

Use the Scan Entities action to scan Google SecOps entities using Nmap.

This action runs on the following Google SecOps entities:

  • IP Address
  • Hostname
  • Domain

Action inputs

The Scan Entities action requires the following parameters:

Parameter Description
IP Address

Optional.

The IP addresses to scan.

These IP addresses are processed alongside entities.
Hostname

Optional.

The hostnames to scan.

These hostnames are processed alongside entities.
Options

Required.

Specifies the Nmap scan parameters.

The default value is -sT -sV -p- -T4 -v.

These options initiate a TCP connect scan (-sT), enable version detection (-sV), scan all 65,535 ports (-p-), use an aggressive timing template (-T4), and increase verbosity (-v).

Action outputs

The Scan Entities action provides the following outputs:

Action output type Availability
Case wall attachment Not available
Case wall link Not available
Case wall table Not available
Enrichment table Available
JSON result Available
Output messages Available
Script result Available
Entity enrichment table

The Scan Entities action supports the following entity enrichment:

Enrichment field Source (JSON key) Logic
NMAP_state status_state When available
NMAP_related_addresses_{addrtype} For each addrtype, provide a comma-separated list of {addr} values. When available
NMAP_related_hostnames hostnames.name When available
NMAP_port_{ports.portid}

{ports.state.state} - {ports.service.product}

This entry dynamically creates a field for each detected port, displaying its state (e.g., open, closed) and the service running on it.

 When available
NMAP_os_matches CSV of {os.osmatches.name} When available
NMAP_last_boot {uptime.lastboot} When available
JSON result

The following example shows the JSON result output received when using the Scan Entities action:
