NODE HARDENING V4

Deploying a Zeqron node in a hostile environment requires more than just cryptographically secure software. This guide outlines the mandatory hardening steps for any node participating in the Genesis Lattice.

OS LEVEL HARDENING

1. ::KERNEL_LOCKDOWN: Disable module loading after boot.

   bash_BUFFER

   Capture_Output

   sysctl -w kernel.modules_disabled=1

2. ::SECOMP_PROFILES: Enforce strict syscall filtering for the zeqron-node process.
3. ::FIREWALL: Only ports 26656 (Gossip) and 26657 (RPC) should be reachable.

NETWORK ISOLATION

• ::P2P_ENCRYPTION: All gossip traffic is forced through Noise-Protocol handshakes using ML-KEM-768.
• ::PRIVATE_SENTRY_NODES: Validators must hide behind a layer of sentry nodes to prevent direct DDoS attacks on the signing keys.
