Dedicated Server Security Hardening

Dedicated servers eliminate neighbor noise from virtualization but place full kernel and hardware attack surface in your hands. Nexelya and Nexelya secure datacenter physical access, network edge DDoS mitigation policies where applicable, and platform APIs—you secure everything from the bootloader up.

Treat IPMI as a highly privileged channel. Separate management VLANs, firewall rules, and logging on BMC access reduce lateral movement if application credentials leak.

Disable unused BMC features (LLDP discovery, default HTTP if HTTPS is available) per vendor guidance.

Apply CIS benchmarks or your internal golden image. Minimize installed packages, enable SELinux or AppArmor where compatible, and configure auditd for authentication events.

For public services, place reverse proxies on the host or separate edge VPS to absorb TLS and WAF duties—dedicated hardware can focus on application throughput.

• Full-disk encryption for laptops is unrelated; for servers, encrypt data volumes if threat model requires at-rest protection and key escrow exists.
• Separate application users—no services as root.
• Centralize logs to immutable storage.

Request additional IPs or VLANs when isolating database tiers from DMZ web fronts. Use host firewalls even behind perimeter firewalls—defense in depth catches misconfigurations.

Document all listening ports with ss -tulpn monthly and alert on drift.

PCI, HIPAA, and SOC workloads on dedicated metal still require vulnerability scanning, access reviews, and backup encryption. Nexelya audit logs supplement but do not replace guest-level compliance evidence.

Engage Nexelya for managed security operations if internal staffing cannot maintain continuous monitoring—see nexelya.com.

Bare metal does not imply automatic compliance; HIPAA and SOC still require process and logging evidence on the OS.

Disk encryption with TPM or LUKS protects at-rest data if drives are removed, but key escrow must exist for legitimate recovery.

Air-gapped backups are ideal for ransomware resilience; at minimum, immutable S3 Object Lock buckets help.
