Snowflake is one of the most popular cloud-based data warehousing platforms currently available. Offered in a Software-as-a-Service or SaaS model, Snowflake takes advantage of unique architecture and full support for ANSI SQL to provide unmatched features and functionality for companies seeking a versatile data platform. Migrating to Snowflake can bring many benefits to businesses of all sizes, provided you understand the security features integrated into Snowflake and follow the security best practices.
Security is a crucial aspect of any cloud-based data solution. Snowflake comes with a full suite of security features that can help you eliminate potential risks and issues. Let us take a look at some of the most important Snowflake security best practices you need to follow.
Snowflake makes use of multiple techniques to secure user data. This security is divided into three concentric layers: network security, identity & access management, and data encryption. To understand and follow Snowflake security best practices, you need to understand all three of these aspects and find out the best practices for each layer applicable to your unique use case. Within each layer, there are several things you can do to enhance overall security.
With network security features, you can successfully isolate your instance of Snowflake from outside attacks and unauthorized access. These features can also be used to set up secure access for cloud storage and client applications with Snowflake.
Here are some things to do:
Creating and authorizing the right users is a crucial part of securely accessing Snowflake. You can use different security features to manage users, sessions, and authentication. Here are some pointers:
OAuth is the most preferred method of authentication if you want heightened security. Snowflake supports both Snowflake OAuth and external OAuth.
Data encryption is an integral part of data security. Snowflake encrypts all stored data using transparent encryption and a key hierarchy. Individual data pieces are encrypted using different keys, and the keys are automatically rotated every 30 days. Users can also opt for encryption through a customer-managed key. Here are some points to remember:

Once you have all these Snowflake security best practices in place, you need to set up proper monitoring to understand if your measures are working correctly. Monitoring can be crucial for the compliance and audit requirements of your organization.
To facilitate this, one thing that can come in handy is Snowflake's built-in shared account usage database, which can give you access to a year's worth of audit logs. The login history logs all connections made with Snowflake and a query history that logs every Snowflake query. You can also retain audit data for more than a year by moving this data into a custom database. You can use the user account usage view to get user-specific access information or access the grants account usage views to see where each user has access.
Row-level security in Snowflake is a feature that enables organizations to control access to specific rows within a database table based on a user's role or other attributes. This enhances data security by preventing unauthorized access to sensitive information, and it enables organizations to enforce compliance with data privacy regulations such as GDPR and HIPAA. By limiting access to only the data that a user needs to perform their job, row-level security also helps to prevent accidental data breaches or other security incidents.
The importance of row-level security in Snowflake is due to the increasing need for organizations to secure their data and ensure that it is not misused. With the rise of big data and the Internet of Things (IoT), organizations are collecting and storing massive amounts of data, much of which is sensitive. This data needs to be protected from unauthorized access, theft, or accidental misuse, which can result in data breaches, loss of reputation, and potential financial penalties.
Snowflake provides a flexible and scalable security architecture that allows organizations to define and enforce security policies at the row level. This allows organizations to control access to data based on a user's role, department, or other attributes, which helps to ensure that only authorized users can access sensitive information.
To implement row-level security in Snowflake, you need to follow these steps:
In conclusion, row-level security in Snowflake is a critical tool for organizations that need to secure their data and ensure compliance with data privacy regulations. It enables organizations to control access to specific rows within a database table based on a user's role or other attributes, which helps to prevent unauthorized access to sensitive information. By following the steps outlined above, organizations can implement row-level security in Snowflake and take a crucial step towards securing their data and protecting their reputation.

Snowflake provides several ways to ensure that users only have access to the data they're authorized to see, including role-based access control, row-level security, and data masking. With role-based access control, you can assign specific roles to users and limit the data they can access based on those roles. Row-level security allows you to restrict access to specific rows in a database table based on a user's role or other attributes. Data masking enables you to mask sensitive data so that it is not viewable by unauthorized users.
Snowflake supports a variety of authentication methods, including single sign-on (SSO) using SAML, Snowflake internal user authentication, and Snowflake external OAuth authentication. You can also authenticate using Snowflake authentication methods such as username/password or Snowflake access keys.
Yes, Snowflake provides built-in encryption for sensitive data at rest, which includes all data stored within Snowflake databases. By default, Snowflake uses Advanced Encryption Standard (AES) 256-bit encryption to secure all data stored within Snowflake. This encryption is applied automatically, ensuring that sensitive data is protected even if a database or table is inadvertently left unsecured. Additionally, Snowflake allows you to configure your own encryption keys, providing even greater security for your sensitive data.
Remaining secure is crucial to meet compliance requirements and to keep the reputation of your business intact. While following these Snowflake security best practices might be enough to secure your data currently, it is important to remember that security threats evolve. Therefore, your strategies should evolve accordingly. Stay updated about the latest security trends and come up with proactive solutions.
