You'll configure, break, fix, harden, and verify-until your server is production-tough.What you'll master (with copy-paste labs)Interfaces, IP & DNS: ip, nmcli, netplan, resolvectl, default routes that actually route.Traffic & services: ss, systemctl, journalctl, tcpdump, iperf3 for real diagnostics.Firewalls: modern nftables (plus ufw/firewalld), default-deny rules, logging, and sets.SSH hardening: keys-only auth, no-root login, Fail2Ban bans that stick.VPNs: fast WireGuard (and when to pick OpenVPN or StrongSwan/IPsec).Zero Trust basics: identity-aware access with practical starter tools.System hardening: SELinux/AppArmor in enforcing mode-labels, booleans, profiles.Auditing & compliance: Lynis, OpenSCAP, CIS Benchmarks-what to fix first.IDS/IPS: Suricata alerts that actually catch brute-force and port scans.Patch automation: unattended-upgrades, dnf-automatic, and live-patch options.Inside the bookPractice Labs 1-7: short, focused labs that build real muscle memory.Capstone Project: deploy a multi-service secure server (Web + SSH + WireGuard) with nftables, SELinux/AppArmor, Suricata, and automated updates-then attack it and verify your defenses.Cheat Sheets & Templates: quick-reference for ip, ss, nmcli, nftables, journalctl, plus ready-to-use WireGuard/OpenVPN/StrongSwan configs.Troubleshooting Guide: fix the errors everyone hits-handshakes, DNS, routes, SELinux denials, firewall drops.Hardening & Audit Reference: map findings to CIS and track progress with Lynis scores.Who this is forBeginners and career-switchers who want a practical path into Linux networking & security.Homelab builders who want private, safe remote access.Cloud & on-prem admins/DevOps who need a clear, modern baseline they can trust.Why this bookPurely practical: every concept lands in a terminal.Modern & up to date: nftables, WireGuard, systemd-resolved, SELinux/AppArmor, Suricata-the current toolchain.End-to-end coherence: networking, security, hardening, monitoring, and patching working as one system.If you can type commands, you can build a hardened Linux server.Open the book, run the labs, ship a secure system-today.", "item_img_path" : "https://covers3.booksamillion.com/covers/bam/9/79/826/604/9798266041950_b.jpg", "price_data" : { "retail_price" : "24.99", "online_price" : "24.99", "our_price" : "24.99", "club_price" : "24.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
