DNS whitelisting in Snowflake is a security feature that allows you to restrict access to your Snowflake account to specific IP addresses or ranges. This can be useful for preventing unauthorized access to your data, or for meeting compliance requirements.
To configure DNS whitelisting in Snowflake, you need to take the following steps:
- Log in to the Snowflake web interface and navigate to the “Account” menu.
- Select “Security” from the submenu.
- In the “Security” page, select the “DNS Whitelisting” tab.
- In the “DNS Whitelisting” tab, click on the “New” button to add a new whitelist entry.
- In the “Add Whitelist Entry” dialog, enter the IP address or IP range that you want to whitelist. You can also enter a CIDR notation.
- You can also specify the scope of the whitelist, this option allows you to specify if the whitelist is applied to all regions or only to specific regions.
- Select the “Apply” button to save the new whitelist entry.
- Repeat the process to add more whitelist entries as needed.
Once you have added the whitelist entries, Snowflake will only allow connections from the specified IP addresses or ranges. Any other connections will be denied.
It’s important to note that whitelisting IP addresses will only affect connections to Snowflake. If you have other services or applications that are dependent on Snowflake, you will also need to whitelist their IP addresses as well. Additionally, it’s a good practice to regularly review and update the whitelisted IP addresses to keep them up to date.
In summary, DNS whitelisting in Snowflake is a security feature that allows you to restrict access to your Snowflake account to specific IP addresses or ranges, it’s an important step to secure your data and meet compliance requirements.
