Security Reality Check

Persistent Storage is Detectable

The Reality: If someone physically examines your Tails USB drive, they can detect that encrypted persistent storage exists. While they can't read the contents without your password, the mere presence of encrypted data may be suspicious.

Mitigation Strategies:

  • Use separate drives: Keep sensitive persistent data on a hidden drive
  • Plausible deniability: Use a decoy Tails with innocent persistent data
  • RAM-only mode: For maximum security, avoid persistent storage entirely

Hardware Fingerprinting Still Possible

The Limitation: Your computer's hardware configuration (CPU, RAM, screen resolution, timezone, MAC address) can create a unique fingerprint. Advanced adversaries can potentially correlate this across sessions.

Protection Methods:

  • MAC spoofing: Tails randomizes your MAC address automatically
  • Use different computers: Rotate between various machines and locations
  • Public networks only: Never use your home internet for sensitive activities

Performance Trade-offs

The Reality: Tails runs entirely from RAM and routes all traffic through Tor, making it significantly slower than normal computing. This is the price of anonymity.

Optimization Tips:

  • More RAM helps: Tails 7.0 requires minimum 3GB, more improves performance
  • Fast USB 3.0: Use high-speed USB drives for better boot and app loading times
  • Minimize multitasking: Close unused applications to free up RAM
