Browsing to any of the PHP files in the dmxConnect directory outputs JSON data

I’ve tried to see if this has been discussed before but couldn’t find anything. I’ve just realised that browsing to any of the PHP files in the dmxConnect folder shows JSON output of data. Is this a security risk? Should I be doing something in Server Connect to prevent this or is there a global setting (.htaccess in that folder, perhaps?) to stop this happening. I became aware as I’m working on a CRON job to automate something and so browsed to the script to test it and realised the issue.
