**Tripwire: The Ultimate Anti-Evil Maid Defense**

In today's world of increasing cybersecurity threats, protecting your devices from physical attacks has become a top priority. One such threat is the evil maid attack, where an attacker gains physical access to your device and compromises its security without you even noticing. But fear not, for we have discovered a robust monitoring system called Tripwire that defends against sophisticated adversaries.

**What is Tripwire?**

Tripwire is a tamper-evident monitoring system designed to detect and prevent evil maid attacks. It works by sharing random secrets between the server (running on a Raspberry Pi 5) and the web client on your mobile device. When an attacker compromises both devices, they cannot restore these secrets, making it impossible for them to cover their tracks.

**How Does Tripwire Work?**

The process of setting up Tripwire is straightforward:

1. Set up your Raspberry Pi 5 as a headless computer following official docs. 2. Connect the PIR sensor and camera module to the Raspberry Pi. 3. Share random secrets between the server and web client using encryption. 4. Deploy the instance directory, which contains both server and client configs. 5. Run the shell scripts to set up environment variables for Caddy's config file.

**Key Features of Tripwire**

1. **Tamper-evident monitoring**: Tripwire detects any intrusion or compromise by an attacker. 2. **Real-time alerts**: Receive web push notifications when an attack is detected. 3. **Secure secrets management**: Random secrets are shared between the server and client, making it impossible for attackers to cover their tracks. 4. **Photo verification**: Verify signatures of photos captured during an attack using ed25519 algorithm.

**Testing Tripwire**

Before deploying Tripwire in a production environment, test its intrusion detection with yourself a few times to get familiar with its user interface. You can also use the "Re-acquire Missing Photos" feature to recover lost photos during temporary network outages.

**Tripwire and Defense-in-Depth**

While Tripwire provides robust protection against evil maid attacks, it is essential to implement multiple layers of defense in your overall cybersecurity strategy. Consider combining Tripwire with other security measures like Random Mosaic (storing devices in a pile of beads or beans) and TPM + Secure Boot for an unparalleled level of protection.

**Conclusion**

Tripwire offers a reliable solution to the evil maid attack threat, providing real-time alerts and secure secrets management. By implementing this robust monitoring system, you can protect your devices from sophisticated adversaries and ensure your data remains safe. So why wait? Deploy Tripwire today and safeguard your digital assets against physical attacks!
