      "Id": "DBforPostgreSQL110",
      "ControlSeverity": "High",
      "Automated": "No",

      "Rationale": "Granting minimum access ensures that users are granted just enough permissions to perform their tasks. This minimizes exposure of the resources in case of user/service account compromise.",

      "ControlSeverity": "High",
      "Automated": "Yes",
      "MethodName": "CheckPostgreSQLSSLConnection",
      "Rationale": "Enforcing SSL connections between your database server and your client applications helps protect against 'man-in-the-middle' attacks by encrypting the data stream between the server and your application.",

      "Rationale": "The 'Allow access to Azure services' setting configures a very broad range of IP addresses from Azure as permitted to access the PostgreSQL Server. Please make sure your scenario really requires this setting before enabling it. Turning it ON exposes your PostgreSQL Server to risk of attacks from resources (IPs) owned by others in the Azure region.",

      "Rationale": "Azure Database for PostgreSQL offers backup/disaster recovery up to 35 days. It also provides the flexibility to choose between locally redundant or geo-redundant backup storage. When processing critical workloads, a team must have adequate backups of the data.",
