COVERT Protocol Action #7: Harden your Devices

Harden your Devices: strengthen the security and privacy of your phones, tablets, laptops, and desktop computers by reducing their attack surface, protecting stored data, and blocking common threats. This includes encrypting data at rest, securing network traffic, tightening web browsing, and using malware protection. Hardened devices are much safer if lost, stolen, or actively targeted.

Steps to Harden Your Devices:

1. Enable full disk encryption (FDE): Turn on encryption for your device’s storage so that data is

unreadable without your passcode, even if the device is lost or stolen. Most modern OSes allow

this (e.g., BitLocker on Windows, FileVault on macOS).

2. Use a VPN connection: Install and configure a reputable Virtual Private Network (VPN) on each

device. This encrypts your network traffic when you are on untrusted Wi-Fi or public networks,

making it harder for attackers to intercept your communications.

3. Harden your browser: Choose a browser that respects privacy, or harden Firefox yourself. Enforce HTTPS for secure connections.Install privacy/security extensions (e.g., script blockers, ad blockers) to reduce tracking and malicious content. Regularly clear cookies and site data. This reduces exposure to trackers and exploitation.

4. Harden you device: Keep software updated. Install antivirus/anti-malware software. Remove unnecessary software. Use least-privilege accounts. Review privacy/security settings. Back up your data
