Cyberspace levels will always have a set of 4 challenges for you to complete. The challenges are:
-Reaching the goal
-Achieving S rank (time based)
-Reaching the goal with a minimum required number of rings
-Finding all red star rings
As the very first level in the game is a cyberspace level (1-1), you can unlock this achievement as soon as you finish the challenges, this might even be the very first achievement you unlock in this game. 1-1 is a very easy level, almost all of them at cyberspace are, really.
Don't worry, you don't have to finish all the challenges in one run of the level, you can do them individually.
Furthermore, you can always repeat any cyberspace level by pressing the
button during the endgame screen.
I'll attach a guide of all cyberspace levels and their challenges here. All credit goes to OmegaX.
