Set up a security.txt file in Moodle LMS

As part of our strategy to improve visibility of our security processes and resources, I'd like to implement a security.txt file.

This is an emerging standard to provide easy to access information about our policies, how to submit security issues etc. I think the best time to look into this is after we are set up with BugCrowd, as this will boost visibility of the new program/reporting procedures, and we will also have much more comprehensive policy/scope documentation to link to.

More information can be found at the security.txt website.
