Data at rest
All datastores with customer data, in addition to S3 buckets, are encrypted at rest. Sensitive collections and tables also use row-level encryption.
This means the data is encrypted even before it hits the database so that neither physical access, nor logical access to the database, is enough to read the most sensitive information
Data in transit
Bucephalus uses TLS 1.2 or higher everywhere data is transmitted over potentially insecure networks. We also use features such as HSTS (HTTP Strict Transport Security) to maximize the security of our data in transit. Server TLS keys and certificates are managed by AWS and deployed via Application Load Balancers.
Encryption keys are managed via AWS Key Management System (KMS). KMS stores key material in Hardware Security Modules (HSMs), which prevents direct access by any individuals, including employees of Amazon and Bucephalus. The keys stored in HSMs are used for encryption and decryption via Amazon’s KMS APIs.
Application secrets are encrypted and stored securely via AWS Secrets Manager and Parameter Store, and access to these values is strictly limited.
