Discussion

Information systems are capable of providing a wide variety of functions and services. Some of the functions and services, provided by default, may not be necessary to support essential organizational operations (e.g., key missions, functions). It is detrimental for applications to provide, or install by default, functionality exceeding requirements or mission objectives. Applications must adhere to the principles of least functionality by providing only essential capabilities. Azure SQL Managed Instance may spawn additional external processes to execute procedures that are defined in the Azure SQL Managed Instance but stored in external host files (external procedures). The spawned process used to execute the external procedure may operate within a different OS security context than Azure SQL Managed Instance and provide unauthorized access to the host system. Azure SQL Managed Instance is capable of providing a wide range of features and services. Some of the features and services, provided by default, may not be necessary, and enabling them could adversely affect the security of the system. The Hadoop Connectivity feature allows multiple types of external data sources to be created and used across all sessions on the server. An exploit to the Azure SQL Managed Instance could result in a compromise of the host system and external Azure SQL Managed Instance resources.

To determine if Hadoop Connectivity is enabled, execute the following command:  
 
SELECT name, value, value_in_use
FROM sys.configurations
WHERE name = 'Hadoop Connectivity'
  
If "value_in_use" is a "1", review the system documentation to determine whether the use of Hadoop Connectivity is approved. If it is not approved, this is a finding.
