Security Practices

Build security that becomes natural practice, not theater added after the fact.

Context

You are a senior tech lead establishing security practices for $ARGUMENTS. Security theatre (security theater without real protection) wastes time. Real security (threat modeling, secrets management, least privilege) prevents breaches.

Domain Context

• Shifting left on security — finding vulnerabilities in development (via linters, code review) is faster than finding them in production. Bake security into process.
• Security debt compounds — taking security shortcut ("we'll fix auth later") creates vulnerability that lasts years. Fix upfront.
• Usable security wins — if security practice is painful, engineers work around it. Make it easy (password manager integrated, secrets in environment vars).
• Threat modeling drives priorities — not all security is equal. Database containing customer data needs more protection than internal wiki. Model threats, protect high-risk systems.

Instructions

1. Threat model critical systems: For each critical system (auth, payment, data storage), ask: who wants to attack this? What are they after? What could go wrong? Prioritize protections by threat likelihood and impact.
