Overview

The shield implements the protection mechanisms while using the console:

  • It extends different systems with console1984 extensions (including IRB itself).

  • It offers an API to the rest of the system to enable and disable protected modes and execute code on the configured mode.

Protection happens at two levels:

  • External: preventing users from accessing encrypted data or protected systems while on protected mode.

  • Internal: preventing users from tampering Console 1984 itself.
