Cheat Prevention specifications
===============================

Due to technical issues, the prevention level is lowered in multiplayer modes. In order to keep away the suspicion, demos recorded in multiplayer modes should never be accepted in contests intended for individual performance.

- Cvars protection
  Defrag uses its own security schemes over sensitive cvars.

- Demo validation
  Demo data is checked for validity during playback.

- Bsp checksum verification
  Ensures that the bsp file used in a demo matches the local version.

- Timer Encryption
  Ensures the authenticity of a demo.
  
- Authentication
  Ensures that the client module is proper, by the mean of an authentication process.
