macOS App Sandbox vs. Windows Integrity Levels: Securing Local Storage in Presenter Privacy Tools
Architectural study of operating system sandboxing primitives. How Chameleon isolates local state using macOS App Sandbox and Windows Low Integrity levels.
A privacy application must adhere to rigorous cybersecurity standards. Implementing strict sandbox isolation guarantees that private notes, API keys, and interview logs remain impervious to unauthorized extraction.
The Security Mandate: Protecting User Credentials on Shared Machines
Engineers often use work or shared hardware. If an application stores sensitive session tokens in unprotected ~/.config directories, other processes or IT scripts can inspect them.
macOS App Sandbox & Container Entitlements
On macOS, Chameleon runs under App Sandbox rules, restricting filesystem reads to isolated container paths and strictly guarding outbound networking.
Windows Mandatory Integrity Control (MIC) & AppContainer
On Windows, Chameleon leverages Mandatory Integrity Control (MIC) to execute child web rendering threads at Low Integrity levels, preventing write access to sensitive registry hives and system directories.
Secure In-Memory Keychain Storage for AI Tokens
Authentication credentials are encrypted using AES-256 GCM backed by OS hardware security modules (Apple Secure Enclave and Windows TPM).
