  1. Best Practices for Server Hardening Here’s how to improve your privacy online. Install only the necessary software to minimize the system's attack surface. Use Secure and Minimal Installations 01 Turn off unneeded services (e.g., FTP, Telnet) and close unused ports. Disable Unnecessary Services and Ports 02 Enforce MFA and use strong encryption (SSL/TLS) for all sensitive data. Use Strong Authentication and Encryption 03 Automate patch management with tools like WSUS or SolarWinds. Apply Security Patches and Updates Regularly 04 Implement least privilege access by assigning permissions based on roles. Set up Role- Based Access Control (RBAC) 05 Restrict access to admins via VPN and enforce strong password policies. Secure Administrative Access 06 Set up a host-based firewall and configure IPS/IDS for traffic inspection. Configure Firewall and Network Security 07 Enable system and security logging; integrate with SIEM for real-time alerts. 08 Monitor Logs and Set Alerts Use tools like Tripwire or AIDE to monitor critical system files for unauthorized changes. Implement File Integrity Monitoring 09 Use vulnerability management tools to scan for and remediate risks proactively. Conduct Regular Vulnerability Scanning 10 Encrypt disks and backups to protect data even if the server is physically compromised. Enforce Full Disk Encryption (FDE) 11 Configure secure boot to prevent unauthorized firmware or OS changes. 12 Implement Secure Boot and BIOS Passwords Set up automated backups of system configurations for easy recovery after a misconfiguration. Backup Configurations Regularly 13 Follow best security practices for VMware, Hyper-V, or other virtualized infrastructures. Secure Virtualization Environments 14 Test Server Hardening with Penetration Testing Regularly conduct pen tests to identify weaknesses and validate hardening efforts. 15 www.centextech.com Centex Technologies 13355 Noel Road, Suite #1100 Dallas, TX 75240 Phone: (972) 375 - 9654 1201 Peachtree ST NE, 400 Colony Square #200 Atlanta, GA 30361 Phone: (404) 994 - 5074 Capital Factory, 701 BrazosStreet, Suite 500 Austin, TX 78701 501 N. 4th Street, Killeen, TX 76541 Phone: (512) 956 - 5454 Phone: (254) 213 - 4740
