Cyber Resilience: Hardening Home Networks Against Disruption

Most 'cyber' preparedness is mundane. The goal is not to defeat advanced threats — it is to keep working when upstream services degrade.

Local-first basics

• Keep offline copies of critical documents (IDs, insurance, medical, deeds) on an encrypted USB stored separately.
• Maintain a printed contact list; phone batteries die.
• Download offline maps for your region on at least one device.
• Keep a small amount of cash on hand — card networks depend on connectivity.

Network hardening

• Change default router credentials and disable remote admin.
• Segment IoT devices onto a guest network.
• Keep firmware current; unpatched routers are the most common entry point.

Resilience is layered. No single step is decisive; together they compound.
