🧠 What is OPSEC?

OPSEC is the process of identifying, assessing, and protecting critical information from exploitation. It’s not just tools—it’s mindset, discipline, and lifestyle.

📌 Core OPSEC Principles

• Don't overshare (online or offline)
• Segregate identities: use alias, burner emails, and different devices
• Only connect to trusted networks; avoid public Wi-Fi or use secure VPNs
• Be invisible digitally—turn off location, permissions, and telemetry

🛠️ Tools to Support Your OPSEC

• GrapheneOS – Hardened OS for Pixel phones
• RethinkDNS – App firewall & DNS-based blocking
• Kuketz Blog – Deep dives into mobile privacy
• Proton Mail & VPN – Secure Swiss-based services
• Tor Browser – For anonymous browsing

📦 Compartmentalization Techniques

• One SIM = One Purpose = One Account
• Isolated logins, VPN tunnels, and browser containers
• Use offline tools (KeePass, Aegis, etc.) for credentials and codes
