# Cleartext Network Traffic

## Overview
Sending data over HTTP (not HTTPS) exposes it to eavesdropping, especially on:
- Public WiFi networks
- ISP-level interception
- Corporate proxies
- Nation-state adversaries

Sensitive operations that must use HTTPS:
- Login and authentication
- API calls with tokens or session cookies
- Payment and financial transactions
- Personal data transmission

## Detection Strategy
- HTTP URLs hardcoded for API endpoints
- HTTP clients configured without TLS
- Mixed content: HTTPS page loading resources over HTTP

## Remediation
- Use HTTPS for all network communication
- Enable HSTS to prevent downgrade attacks
- Add HTTP→HTTPS redirect at server level
