TEE

Definition

A Trusted Execution Environment (TEE) is a secure area within a main processor that ensures the integrity and confidentiality of code and data loaded inside it. It provides an isolated execution environment that runs alongside the main operating system, protecting sensitive computations from potentially malicious applications. TEEs are commonly used in mobile devices and other hardware to safeguard cryptographic operations, secure key management, and protect sensitive data from unauthorized access.

Secure Settings Example

# Example configuration for a TEE-enabled application
tee_configuration:
  enable_tee: true
  secure_storage: true
  isolation_level: high
  access_control:
    - allow: trusted_applications
    - deny: untrusted_sources

Insecure Settings Example

# Example of insecure TEE configuration
tee_configuration:
  enable_tee: false  # Disabling TEE negates its security benefits
  secure_storage: false  # Sensitive data is not protected
  isolation_level: low  # Weak isolation increases risk of data leakage
  access_control:
    - allow: all_sources  # Permissive access control undermines security
