Tenable Security Center

The Tenable Security Center integration tells you which hosts on your enterprise network are either undefended by Tenable or unknown to Asset Manager. By comparing Asset Manager's comprehensive index of all your network devices against that subset of network devices managed by Tenable, you can generate a list of network hosts that are not managed in by Tenable and then push that information to an asset group on Tenable. What's pulled from Tenable to Asset Manager is only what you request, and not an exhaustive collection of all the device details and attributes that Tenable manages. This enables Asset Manager to scan the network device attributes of value to you, and not all the rest.

Configure the Tenable Feed

Configure the integration as follows:

  1. In Asset Manager, go to Settings > Integrations > Tenable Security Center, and then click Configure. 
  2. Turn on the Enabled toggle to activate the integration.
  3. Enter a Polling Interval (by Hour)to indicate the time that should elapse between fetching the latest feed data. Input 24 to poll daily, input 12 to poll twice a day, and so on.
  4. Enter the DNS name or IP address of your Tenable server in the Server Name field.

  5. Select the Authentication type, either API Key or Username/Password and then input the needed credentials.

  6. Select the Pull checkbox for the Zones you want to bring data from Tenable into Asset Manager.
  7. Click Test to confirm that the feed is configured correctly.
  8. Click Save.  

In the Tenable Security Center

To confirm that Asset Manager discovered data has been pushed to Tenable Security Center:

  1. Log in to the Tenable server using the same credentials you used to configure the integration in Asset Manager. 
  2. In the rSecurity Center menu, click Assets.
  3. This is the Asset Manager Asset List within Tenable Security Center.
  4. To manually edit the static list of IPs that came from Asset Manager, click the Asset Manager Asset List group.

  1. Log in to the Tenable Security Center as a user who has system settings access.
  2. Navigate to Systems, Configuration, and then to Security.  The Authentication Settings will be listed.
  3. Scroll down to Allow Session Management.
  4. Clear the Allow Session Management option, and click Submit.
