# OSS Security
|
||
|
|
|
||
|
|
## Encryption of Connection Credentials
|
||
|
|
|
||
|
|
OpenMetadata ensures that sensitive information, such as passwords and connection secrets, is securely stored.
|
||
|
|
|
||
|
|
- **Encryption Algorithm**: OpenMetadata uses **Fernet encryption** to encrypt secrets and passwords before storing them in the database.
|
||
|
|
- **Fernet Encryption Details**:
|
||
|
|
- Uses **AES-128 in CBC mode** with a strong key-based approach.
|
||
|
|
- **Not based on hashing or salting**, but rather an encryption/decryption method with a symmetric key.
|
||
|
|
- **Secrets Manager Support**:
|
||
|
|
- Users can **avoid storing credentials** in OpenMetadata by configuring an external **Secrets Manager**.
|
||
|
|
- More details on setting up a Secrets Manager can be found here:
|
||
|
|
🔗 [Secrets Manager Documentation](https://docs.open-metadata.org/latest/deployment/secrets-manager)
|
||
|
|
|
||
|
|
## Secure Connections to Data Sources
|
||
|
|
|
||
|
|
OpenMetadata supports **encrypted connections** to various databases and services.
|
||
|
|
|
||
|
|
- **SSL/TLS Support**:
|
||
|
|
- OpenMetadata allows users to configure **SSL/TLS encryption** for secure data transmission.
|
||
|
|
- Users can specify **SSL modes** and provide **CA certificates** for SSL validation.
|
||
|
|
- **How to Enable SSL?**
|
||
|
|
- Each connector supports different SSL configurations.
|
||
|
|
- Follow the detailed guide for enabling SSL in OpenMetadata:
|
||
|
|
🔗 [Enable SSL in OpenMetadata](https://docs.open-metadata.org/latest/deployment/security/enable-ssl)
|
||
|
|
|
||
|
|
## **Additional Security Measures**
|
||
|
|
|
||
|
|
- **Role-Based Access Control (RBAC)**: OpenMetadata allows administrators to define user roles and permissions.
|
||
|
|
- **Authentication & Authorization**: OpenMetadata supports integration with OAuth, SAML, and LDAP for secure authentication.
|
||
|
|
- **Data Access Control**: Users can restrict access to metadata based on policies and governance rules.
|
||
|
|
|
||
|
|
{% note %}
|
||
|
|
- **Passwords and secrets are securely encrypted** using **Fernet encryption**.
|
||
|
|
- **Connections to data sources can be encrypted** using **SSL/TLS**.
|
||
|
|
- **Secrets Managers** can be used to manage credentials externally.
