Before you begin

Tenable Attack Surface Management requires the following permissions to add Cloudflare sources:

• Zone Read — Grants read access to zone management.

• DNS Read — Grants read access to DNS.

To add sources from Cloudflare:

1. In Tenable Attack Surface Management, in the upper-right corner, click the button.

2. In the drop-down list, click Add from Cloudflare.

   The Cloudflare keys window appears with the list of configured API keys.

3. Do one of the following:

   • Click an API key to view the list of available zones or domains the API key has access.

   • (Optional) If you do not have any configured API keys, add a new API key:

     1. Click Add.

        Tenable Attack Surface Management displays the Add Cloudflare key box.

     2. In the Cloudflare account name box, type a name for the Cloudflare account.

     3. In the API key box, copy and paste the API key for your Cloudflare account.

     4. Click Add.

        Tenable Attack Surface Management adds the API key and displays the Available zones window with the list of Cloudflare zones (domain names) the API key has access.

        Note: Tenable Attack Surface Management supports these types of DNS records: A, AAAA, CNAME, MX, NS, TXT, PTR, and SOA.

4. To add a domain to your inventory, click the Add to inventory link next to the domain name you want to add.

   Note: To add all zones to your inventory, click Add all.

Tenable Attack Surface Management adds the Cloudflare assets to your inventory and redirects you to the Inventory page showing the newly added sources. The source from Cloudflare has an orange cloud icon under its name.

If there are assets from outside the zone or domain, Tenable Attack Surface Management automatically adds them as elastic assets. Tenable Attack Surface Management extracts data from these elastic assets using the hostname rather than their IP addresses. The IP column in the Inventory table shows Elastic Asset instead of an IP address for these elastic assets.

To delete a Cloudflare API key:

1. In the Cloudflare keys window, click next to the Cloudflare API key to delete.

   Tenable Attack Surface Management deletes the Cloudflare API key. The sources added using this key still show up in the inventory but Tenable Attack Surface Management eventually deletes them across all inventories.
