What action allows Cortex XSOAR to access Docker in an air-gapped environment?

The correct action that enables Cortex XSOAR to access Docker in an air-gapped environment is to create a "docker" group and add the "Cortex XSOAR" user to this group. This is essential because, in order for software applications like Cortex XSOAR to interact with Docker, the user account under which the application runs must have the appropriate permissions to access Docker's capabilities. By adding the Cortex XSOAR user to the "docker" group, you grant it the necessary privileges to communicate with and manage Docker containers, which is vital for the application's functionality, especially in environments where security and access are tightly controlled, such as air-gapped setups.

This approach ensures that the application can operate effectively while maintaining the security protocols required in such isolated networks.
