This feature combines Snowflake-managed keys with customer-managed keys to create a composite master key, offering enhanced control over data encryption.
In standard Snowflake encryption, data is protected using AES-256 encryption with keys managed entirely by Snowflake through a hierarchical key model. Tri-Secret Secure extends this by incorporating a customer-managed key (CMK) stored in a cloud provider's key management service, such as AWS KMS, Azure Key Vault, or Google Cloud KMS.
The composite master key is created by combining the Snowflake-managed key with the customer-managed key. Both keys are required to decrypt data, meaning neither Snowflake nor the customer can access the data independently. This dual-key approach ensures that customers maintain ultimate control over their encrypted data.
Key benefits of Tri-Secret Secure include enhanced data sovereignty, regulatory compliance support, and the ability to revoke access to data by disabling the customer-managed key. If an organization needs to terminate access to their Snowflake data, they can simply disable their CMK, rendering all data inaccessible.
To implement Tri-Secret Secure, organizations must work with Snowflake to configure the integration between their cloud provider's key management service and their Snowflake account. This requires Business Critical Edition or higher.
The encryption hierarchy in Tri-Secret Secure follows Snowflake's standard model: file keys encrypt individual data files, table keys wrap file keys, account keys wrap table keys, and the composite master key protects the entire hierarchy.
Tri-Secret Secure is particularly valuable for industries handling sensitive data, including healthcare, financial services, and government sectors, where maintaining exclusive control over encryption keys is a regulatory or organizational requirement.
Complete Guide to Tri-Secret Secure Encryption in Snowflake
What is Tri-Secret Secure?
Tri-Secret Secure is Snowflake's most advanced encryption key management feature that combines three separate keys to create a composite master key for encrypting your data. This feature provides customers with the highest level of control over their encrypted data in Snowflake.
The Three Keys in Tri-Secret Secure:
1. Snowflake-maintained key - A key that Snowflake automatically manages and maintains 2. Customer-managed key (CMK) - A key stored in your own cloud provider's key management service (AWS KMS, Azure Key Vault, or Google Cloud KMS) 3. Snowflake account master key - Generated within Snowflake's hardware security module (HSM)
These three keys are combined to create a composite master key that encrypts and decrypts your data.
Why is Tri-Secret Secure Important?
1. Enhanced Security Control - You maintain control over one of the encryption keys, meaning Snowflake cannot access your data alone
2. Regulatory Compliance - Helps meet strict compliance requirements for industries like healthcare, finance, and government
3. Data Sovereignty - Provides an additional layer of protection ensuring only authorized parties can access data
4. Kill Switch Capability - If you disable or delete your customer-managed key, Snowflake loses the ability to decrypt your data, giving you ultimate control
How Tri-Secret Secure Works:
1. You create and manage a key in your cloud provider's key management service 2. You configure Snowflake to use this key alongside its own keys 3. When data is encrypted or decrypted, all three keys must be available 4. If any key is unavailable, the data remains inaccessible
Key Requirements:
- Available only on Business Critical Edition and higher - Requires setup with your cloud provider's key management service - The customer-managed key must remain accessible for Snowflake to function
Exam Tips: Answering Questions on Tri-Secret Secure
Tip 1: Remember that Tri-Secret Secure requires Business Critical Edition or higher. If a question mentions Standard or Enterprise Edition, Tri-Secret Secure is not available.
Tip 2: Know the three components: Snowflake-maintained key, customer-managed key, and Snowflake account master key. Questions may test your knowledge of what comprises the composite key.
Tip 3: Understand the customer control aspect - the main benefit is that customers can revoke Snowflake's access to their data by disabling their customer-managed key.
Tip 4: Be aware that Tri-Secret Secure uses your cloud provider's native key management service (AWS KMS, Azure Key Vault, GCP Cloud KMS) - not a third-party solution.
Tip 5: Remember that this feature is about encryption key management, not about encrypting data in transit or network security.
Tip 6: Questions may present scenarios about compliance requirements - Tri-Secret Secure is often the answer when maximum security and customer key control are required.
Tip 7: Do not confuse Tri-Secret Secure with standard Snowflake encryption. All Snowflake editions include automatic encryption, but Tri-Secret Secure adds the customer-managed key component.
Common Exam Question Patterns:
- Which edition supports Tri-Secret Secure? (Answer: Business Critical or higher) - What happens if the customer disables their managed key? (Answer: Data becomes inaccessible) - How many keys comprise the Tri-Secret Secure composite key? (Answer: Three) - Where is the customer-managed key stored? (Answer: Cloud provider's key management service)
