ZScaler Cloud NSS Feed

Configure ZScaler NSS Cloud HTTPS log forwarding to Radiant Security.

Overview

In this guide, you will create custom log formats for ZScaler NSS Cloud log configuration. This is required in order to send ZScaler logs to Radiant Security through HTTPS.

To do this, you’ll need to complete the following steps:

• Add the data connector in Radiant Security
• Set up NSS Cloud Integration with the Radiant Security Connector

Add the data connector in Radiant Security

1.   Log in to Radiant Security.
2.   From the navigation menu, click Settings > Data Connectors and click + Add Connector.
3.   Search for and select the Zscaler NSS (webhook) option and then click Data Feeds.
4.   Select the ZScaler NSS Cloud data feed and then click Credentials.
5.   Under Credential Name, give the credential an identifiable name (e.g. ZScaler NSS - Token ). If you already have a credential in place, select it from the drop-down menu. Click Add Connector.
6.   In the Connector tag field, enter a random value. This value will act as the salt to randomize the Token you’ll download in the next step. 7.   Click Add Connector.
8.   Copy and save the Token and Webhook URL values. Click Download File to download the SSL Certificate and Custom Template as you will need these files when configuring the HTTPS source.     9.   Click Done to save your changes.
