The world is increasingly built on data. An estimated 120 zettabytes will be created, captured, copied, and consumed this year alone. Yet businesses looking to harness that data for improved decision making traditionally had a problem. Legacy data warehouses required the purchase of expensive hardware which had to be run on-premises in the customer’s datacenter. Costly, complex and inflexible, these solutions held organizations back from achieving their potential.
Snowflake is the best-known of a new breed of SaaS-based offerings designed to offer scale, simplicity and high performance, without breaking the bank. But given the sensitivity of data used in the tool, it’s important to understand the range of powerful security features Snowflake provides and where native controls can be enhanced by third-party solutions – such as data encryption.
In this blog, we'll explore why everyone uses Snowflake and some Snowflake security best practices that can help safeguard your organization’s data in the cloud.
Snowflake is designed to take the pain out of data warehousing. Its multi-cluster, three-layered architecture separates database, compute and cloud services capabilities to deliver a set of advantages over legacy offerings. These include:
An organization’s most important assets are its data. So new Snowflake customers should leverage the platform’s security capabilities as a priority, whilst understanding where these can be enhanced where necessary.
One area where they may benefit from investing in third-party solutions is data encryption – a critical control for mitigating cyber risk on Snowflake. While Snowflake offers Dynamic Data Masking to keep sensitive data hidden from unauthorized users, data must be loaded in plain text into the platform, and a database and schema must exist before a masking policy can be applied to a column. What does this mean? That the data remains unprotected at the database level and when it is used in external applications – meaning there’s a high risk of misconfiguration and data exposure.
Snowflake customers can mitigate these risks with solutions like comforte’s Data Security Platform, which is designed to integrate easily with the data warehousing platform. We offer:
By limiting connections to only known clients, you can ensure that your data is only accessed from trusted sources. Use Snowflake's network policies to block and whitelist IP addresses and address ranges.
Multi-factor authentication (MFA) in Snowflake allows you to add an extra layer of security to your user authentication process. This Snowflake security feature requires users to input a second “factor” such as a one-time code sent to their app, in order to mitigate the risk of password theft.
Leveraging Snowflake’s role-based access control (RBAC) allows you to effectively manage and control user access privileges of a large number of users within your Snowflake account. RBAC enables you to assign users to specific roles based on their job functions, and then provide or restrict access to data based on those rolesThis ensures only authorized users can view or modify data, reducing the risk of data breaches or unauthorized access.
Snowflake’s built-in auditing and logging features allow you to track and monitor all user system activity within your Snowflake account. This includes tracking user activity, monitoring user access to sensitive data and identifying potential security threats so any potential breach can be quickly remediated and contained. Organizations can also configure alerts to notify of any such activity. Monitoring will also enable you to ensure your Snowflake security measures are working once your best practices are in place.
By implementing these best practices, you can improve the security of your Snowflake environment and reduce the risk of data breaches and other security incidents. To learn more about how you can enhance the tool’s native controls, contact the experts at comforte today.
