Server Security Checklist — Essential Hardening Guide

Securing your servers isn’t optional — it’s your first line of defense against data breaches, ransomware, insider threats, and lateral movement. Use this checklist as a baseline for Linux, Windows, cloud, hybrid, or on-prem servers.

⸻

🔧 1. System & OS Hardening
• Keep OS & packages updated (apply security patches frequently).
• Remove / disable unused services & software.
• Enforce secure boot + BIOS/UEFI passwords.
• Disable auto-login and guest accounts.
• Use minimal OS images only (reduce attack surface).

⸻

🔐 2. Access Control
• Enforce strong passwords & MFA everywhere.
• Use RBAC & least privilege access.
• Disable root/Administrator login over SSH/RDP.
• Rotate credentials & keys regularly.
• Implement just-in-time access for privileged users.

⸻

🌐 3. Network Security
• Restrict inbound/outbound traffic via firewalls.
• Segment critical servers from general LANs/VLANs.
• Disable unused ports & protocols.
• Enable DoS/DDoS protection.
• Apply zero-trust network principles.

⸻

🔑 4. Secure Remote Access
• Use SSH key-based authentication (disable password login).
• Enforce VPN for admin access.
• Log & monitor all remote access sessions.
• Disable legacy protocols (Telnet, FTP, SMBv1).
• Require bastion/jump host for critical access.

⸻

📊 5. Logging & Monitoring
• Enable centralized logging (syslog / SIEM).
• Track failed login attempts & anomalies.
• Configure alerts for privilege escalation or config changes.
• Monitor log tampering.
• Retain logs securely for audits & forensics.

⸻

🔒 6. Data Protection
• Encrypt data at rest (LUKS, BitLocker, etc.).
• Encrypt data in transit (TLS 1.2+).
• Strict database access policies.
• Regular, offline, immutable backups.
• Test restore procedures (don’t assume backups work).

⸻

🔁 7. Application & Patch Management
• Keep middleware, frameworks, and apps patched.
• Delete default credentials & sample files.
• Enable code signing for software packages.
• Use secure coding practices (OWASP Top 10).
• Implement dependency scanning (Snyk, Trivy, etc.).

⸻

🛡️ 8. Malware & Intrusion Defense
• Deploy EDR/AV on endpoints.
• Enable IDS/IPS at network edge.
• Automatic vulnerability scans (schedule weekly/monthly).
• Monitor persistence techniques (cron, startup scripts).
• Block known malicious IP ranges & TLDs.

⸻

🏢 9. Physical & Cloud Security
• Restrict physical access to server racks/rooms.
• Enable provider security tools (AWS Security Groups, Azure NSG, IAM).
• Harden cloud images (CIS benchmarks).
• Review cloud logging & audit trails regularly.
• Disable unused cloud API keys / roles.

⸻

📜 10. Policy & Compliance
• Use CIS / NIST / ISO-27001 benchmarks.
• Track & document every access change.
• Force annual access reviews & key rotation.
• Perform regular security training for admins.
• Maintain disaster recovery & incident plans.

⸻

➕ Additional 5 Critical Controls (Advanced Hardening)

🧠 11. Privileged Access Management (PAM)
• Use jump hosts & session recording.
• Just-In-Time access for admins.
• Store keys in secure vaults (HashiCorp Vault, CyberArk).

🚨 12. Real-Time Threat Detection
• Use behavioral analytics → UEBA/XDR.
• AI-based anomaly detection recommended.
• Block suspicious IPs automatically.

🧪 13. Red Team & Pentesting
• Run regular internal pentests.
• Validate configuration weaknesses.
• Simulate phishing + lateral movement scenarios.

🧱 14. Container / VM Isolation
• Use AppArmor, SELinux, Seccomp profiles.
• Limit Docker socket access & root containers.
• Scan images before deployment.

📦 15. Automated Configuration Management
• Use IaC (Terraform, Ansible, Puppet) for repeatable and secure builds.
• Detect drift using compliance scanning.
• Version control all infrastructure.

⸻

🧠 Core Reminder

A server is only as secure as the team who maintains it.
Hardening isn’t one task — it’s an ongoing

🛑 When your crosswalk starts quoting Elon Musk, something’s gone very wrong.

Over the weekend, hackers hijacked audio-enabled crosswalk buttons across Silicon Valley — replacing accessibility messages with AI-generated voices of Elon Musk and Mark Zuckerberg.

Pedestrians in Menlo Park and Palo Alto were met with bizarre, deepfake-style soundbites like:

“There’s absolutely nothing you can do to stop it.”
“I guess money can’t buy happiness… but it can buy a Cybertruck.”

🎯 The punchline? This wasn’t a high-level exploit.
Reports suggest the attackers likely used default credentials that had never been changed.

Let that sink in: public infrastructure, intended to serve the visually impaired, turned into an AI-powered street performance — all because of basic security negligence.

This is bigger than a viral moment:
– Public systems are routinely left exposed
– AI + deepfake tools are trivial to access
– And human oversight remains the weakest link

At @Efani, we believe that real security begins with the basics.
If you haven’t changed your device defaults — you’ve already been compromised.

In a penetration test, automated tools find known vulnerabilities—but they don’t think like an attacker...
 
You can absolutely automate the 'vulnerability assessment' phase and information discovery.

It’s possible to automate some exploitation too, if you’re brave and don’t care about the stability of the customer’s network.
 
However, humans perform penetration testing.

Here's a story that illustrates why: https://www.pentestpartners.com/security-blog/a-tale-of-enumeration-and-why-pen-testing-cant-be-automated/
