feat(query): implements "Beta - SQL DB Instance With Remote Access Enabled"

[cx-andre-pereira]

Reason for Proposed Changes

• Currently there is no query to ensure that a "google_sql_database_instance" resource with a "SQLSERVER" based "database_version" has the 'remote access' flag set to "off".

• Quoting CIS_Google_Cloud_Platform_Foundation_Benchmark_v4.0.0 page 256: "The remote access option controls the execution of stored procedures from local or remote servers on which instances of SQL Server are running. This default value for this option is 1. This grants permission to run local stored procedures from remote servers or remote stored procedures from the local server. To prevent local stored procedures from being run from a remote server or remote stored procedures from being run on the local server, this must be disabled. The Remote Access option controls the execution of local stored procedures on remote servers or remote stored procedures on local server. 'Remote access' functionality can be abused to launch a Denial-of-Service (DoS) attack on remote servers by off-loading query processing to a target, hence this should be disabled.

Proposed Changes

• Implemented the missing query.

• The query will flag for 4 separate instances : (all after ensuring "database_version" is SQLSERVER based (possible values list))

  • Missing the "settings" field
  • Missing the "settings.database_flags" field
  • Missing a definition for the "remote access" flag on the "database_flags" field
  • Setting the "remote access" flag to a value that is not "off" (default value is on)
