Creating Private and Public CTF Competitions - Admin

This KB article will cover how to enable or disable public registration in Cloud CTF. This article is intended for CTF Admins (Cyber Range Instructors). If you do not yet have an account with the Virginia Cyber Range, please see Getting an Instructor Account and Creating Your First Course.

Cloud CTF allows for both private and public CTF competitions by providing a public registration feature in the admin settings of a Cloud CTF environment.

  • Private CTF competitions are the default in Cloud CTF and only allow students enrolled in Virginia Cyber Range courses to access the environment. To learn more about making a Cloud CTF competition private, please see How to Setup a Private CTF Competition below.

  • Public CTF competitions must be enabled in the admin settings of a Cloud CTF environment and allow users from outside of the Virginia Cyber Range to participate in Cloud CTF competitions. To learn more about making a Cloud CTF competition public, please see How to Setup a Public CTF Competition below.


How to Setup a Private CTF Competition

1. To create a private Cloud CTF environment for users enrolled in Cyber Range courses, please get started by first creating a new Cloud CTF environment. Please follow the guide outlined in our KB article, Creating a Cloud CTF Environment.

2. Once you have successfully created your Cloud CTF Environment, please launch the environment.

3. Next, you will need to navigate to the Admin settings of your environment. Please click on Admins, as shown in the image below.

The Admins panel can be found at the top of the screen, as the rightmost of the four choices.

4. You will now need to make sure that public registration is disabled. If the Allow Public Registration box is checked, please uncheck the box and then click on Confirm to save the settings.

The Allow Public Registration box can be found just below the Date and Time section, as the first box.

5. Virginia Cyber Range students that are enrolled in active courses will be able to access the Cloud CTF environment from within the exercise area. Students can be provided with the Getting Started in Cloud CTF player article for more information on accessing the environment.

Once a user navigates to the link, they will be able to register for the CTF competition by using their Facebook, Google, or Microsoft Azure account.

Users from outside of the Virginia Cyber Range can be provided with the Getting Started in Cloud CTF player article for more information on registering for a public CTF competition.
