Security is critical for dedicated servers since you are fully responsible. Recommended practices include:

  • Change the default SSH port and disable password logins in favor of SSH keys.

  • Configure firewalls (UFW, CSF, or iptables).

  • Keep software and the kernel updated.

  • Install intrusion detection systems like Fail2Ban or OSSEC.

  • Restrict root access and enforce sudo usage.

  • Enable regular vulnerability scans.

Proactive hardening helps prevent unauthorized access and downtime.
