Tenable API

This repository contains sample commands for interacting with the Tenable (Nessus) api documented on https://cloud.tenable.com/api#/overview.

Prerequisites

Set your user credentials in creds.json

{
  "username":"[email protected]",
  "password":""
}

Common Commands

Login to get a session token

First login to get a session cookie then include it as X-Cookie for subsequent requests.

Note that Tenable now supports API keys so the X-Cookie is not required. See https://cloud.tenable.com/api#/authorization for more information.

#!/usr/bin/env python2.7

import requests
import json

with open('creds.json') as df:
  data = json.load(df)

session = requests.post('https://cloud.tenable.com/session', data = data)

headers = { 'X-Cookie': 'token=' + session.json()['token']}

requests.get('https://cloud.tenable.com/scanners', headers=headers)
