@kamilsec7: SSH is encrypted… and your server can still get hacked. 🔓 Bots hammer every exposed port 22 all day, guessing passwords. Here are the 5 sshd_config settings that shut them out: 1️⃣ Keys, not passwords 2️⃣ No root login 3️⃣ MFA for admins 4️⃣ Limit who & where (AllowGroups + VPN/bastion) 5️⃣ Idle timeouts + strong, FIPS-approved ciphers Plus the NIST 800-53 controls behind it (IA-2, IA-5, AC-2) and the audit finding nobody talks about: SSH key sprawl 🗝 Save this for your next server build, STIG review, or interview. Part 2 of the SSH series. #KamilSec #SSH #Linux #SysAdmin #CyberSecurity For the pinned comment: “Which setting does your org still skip? 1) keys only 2) no root 3) MFA 4) AllowGroups/VPN 5) timeouts 👇 (Bonus: which NIST IR covers SSH key management?)”
