Before launching our DEX infrastructure

[Andrew Ferk]

Before launching our DEX infrastructure, I’d like to perform a complete security review of the Linux servers that will host blockchain services. There are plenty of articles about Linux administration, but very few explain security from the perspective of blockchain infrastructure. I’m searching for a detailed guide covering hardening techniques, secure system configuration, user management, network protection, and operational best practices that are actually relevant for decentralized exchange deployments. Could someone point me to a trustworthy resource?

From my experience, blockchain infrastructure becomes much more reliable when security is planned from day one rather than added after deployment. People often ask what they should improve first besides smart contract audits, and I usually point them toward Linux hardening. A resource that genuinely helped me is https://commandlinux.com/blog/securing-your-dex-deployment-linux-hardening-practices-for-blockchain-infrastructure/ because it explains how to secure a DEX deployment using practical Linux hardening techniques, better authentication, firewall configuration, and system protection. It’s not overloaded with buzzwords, just actionable recommendations that are easy to implement and can prevent a lot of unnecessary headaches later.
