![]() ![]() This administrator role can be used to create more PostgreSQL roles.įor example, below we can create an example role called demouser, postgres=> create role demouser with password 'password123' While you're creating the Azure Database for PostgreSQL server, you provide credentials for an administrator role. You can see these roles by running the command: SELECT rolname FROM pg_roles The Azure Database for PostgreSQL server is created with the 3 default roles defined. Roles are used to enforce a least privilege model for accessing database objects. You can then assign the appropriate roles to each user. As a good security practice, it can be recommended that you create roles with specific sets of permissions based on minimum application and access requirements. PostgreSQL lets you grant permissions directly to the database users. It is also possible to grant membership in a role to another role, thus allowing the member role to use privileges assigned to another role. Roles can own the database objects and assign privileges on those objects to other roles to control who has access to which objects. A role can be either a database user or a group of database users. For more information, see the overview of firewall rules.īest way to manage PostgreSQL database access permissions at scale is using the concept of roles. IP firewall rules grant access to servers based on the originating IP address of each request. Access to it is secured through a firewall that blocks all connections by default. The public endpoint is a publicly resolvable DNS address. Public access: The server can be accessed through a public endpoint. For more information, see the overview of network security groups. Security rules in network security groups enable you to filter the type of network traffic that can flow in and out of virtual network subnets and network interfaces. For more information, see the networking overview for Azure Database for PostgreSQL - Flexible Server. ![]() ![]() Resources in a virtual network can communicate through private IP addresses. Azure virtual networks help provide private and secure network communication. Private access: You can deploy your server into an Azure virtual network. When you're running Azure Database for PostgreSQL - Flexible Server, you have two main networking options: Storage encryption is always on and can't be disabled. This is similar to other at-rest encryption technologies, like transparent data encryption in SQL Server or Oracle databases. The service uses the AES 256-bit cipher included in Azure storage encryption, and the keys are system managed. Data is encrypted on disk, including backups and the temporary files created while queries are running. You can also set TLS version by setting ssl_min_protocol_version and ssl_max_protocol_version server parameters.ĭata at rest: For storage encryption, Azure Database for PostgreSQL uses the FIPS 140-2 validated cryptographic module. For better security, you may choose to enable SCRAM authentication.Īlthough it's not recommended, if needed, you have an option to disable TLS\SSL for connections to Azure Database for PostgreSQL - Flexible Server by updating the require_secure_transport server parameter to OFF. Information protection and encryptionĪzure Database for PostgreSQL encrypts data in two ways:ĭata in transit: Azure Database for PostgreSQL encrypts in-transit data with Secure Sockets Layer and Transport Layer Security (SSL/TLS). This article outlines those security options. Multiple layers of security are available to help protect the data on your Azure Database for PostgreSQL server.
