# iOS App Transport Security Disabled

## Overview
iOS App Transport Security (ATS) enforces HTTPS and modern TLS for all network connections. Disabling ATS via `NSAppTransportSecurity` plist exceptions allows insecure HTTP connections and weakened TLS, enabling MITM attacks.

## Remediation
- Remove `NSAllowsArbitraryLoads: true`
- Fix server TLS configuration to be ATS-compliant
- Use specific domain exceptions only for legacy systems during migration
