SECURITY PROTOCOL & ADVISORY

Security & Scam Awareness

Running infrastructure connected to peer-to-peer networks requires uncompromising operational security. Follow these guidelines to safeguard your nodes, server credentials, and validator keys.

The Cardinal Security Rules of Node Operation

Never disclose your 12/24-word recovery seed phrase or validator private keys to anyone, including node support groups, Discord bots, or website administrators.
NodeDrops.xyz never requires wallet connections for reading guides, evaluating hardware, or running commands. Any website pretending to be NodeDrops and prompting for a wallet approval is an imposter.
Never pipe remote scripts directly into bash (curl https://example.com/install.sh | bash) without downloading and reading the shell code first.
Never expose RPC ports (8545, 8551, 26657, 9090) to public 0.0.0.0 without authenticated reverse proxies or VPN isolation. Unprotected RPC endpoints can allow external attackers to drain funds or cause denial of service.

Server Hardening Standards

1. Ed25519 Key-Only SSH

Disable password authentication in /etc/ssh/sshd_config. Set PasswordAuthentication no and reload sshd.

2. Strict Firewall (UFW)

Block all incoming ports by default. Explicitly allow only your custom SSH port and verified P2P ports (e.g. 30303 for Geth).

3. Fail2ban Protection

Deploy Fail2ban to automatically blacklist IP addresses scanning for open SSH or port exploits.

4. Isolated Service Accounts

Run node client software under unprivileged dedicated system users with locked login shells (/usr/sbin/nologin).
