<\/div>

1. Initial Setup<\/strong><\/h3>\n
    \n
  • Change Default Passwords:<\/strong> Replace all default admin\/root passwords with strong, unique credentials.<\/li>\n
  • Create a Non-Root User:<\/strong> For daily tasks, use a regular user account with sudo privileges instead of root.<\/li>\n
  • Update the System:<\/strong> Apply all available OS and software updates\/patches immediately after deployment.<\/li>\n<\/ul>\n

    2. Network Security<\/strong><\/h3>\n
      \n
    • Configure a Firewall:<\/strong> Use tools like ufw<\/code>, firewalld<\/code>, or iptables<\/code> to restrict open ports to only what\u2019s necessary.<\/li>\n
    • Disable Unused Services and Ports:<\/strong> Shut down all services and close ports that you don\u2019t actively need.<\/li>\n
    • Use SSH Keys:<\/strong> Disable password-based SSH logins; only allow authentication via SSH keys.<\/li>\n
    • Change Default SSH Port:<\/strong> Consider moving SSH from port 22 to a non-standard port to reduce automated attacks.<\/li>\n
    • Enable Fail2ban:<\/strong> Install Fail2ban or similar tools to block IPs after repeated failed login attempts.<\/li>\n<\/ul>\n

      3. Software & System Hardening<\/strong><\/h3>\n
        \n
      • Remove Unnecessary Packages:<\/strong> Uninstall software you don\u2019t use to minimize vulnerabilities.<\/li>\n
      • Install Security Updates Automatically:<\/strong> Set up automatic security updates if possible, or schedule regular manual checks.<\/li>\n
      • Use Secure Protocols:<\/strong> Ensure services like FTP or HTTP are upgraded to SFTP\/FTPS and HTTPS.<\/li>\n
      • Run a Malware Scanner:<\/strong> Deploy tools (like ClamAV, rkhunter, or chkrootkit) for regular scans.<\/li>\n<\/ul>\n

        4. Account and Access Control<\/strong><\/h3>\n
          \n
        • Audit User Accounts:<\/strong> Regularly review user accounts and permissions; disable or remove old\/unused accounts.<\/li>\n
        • Implement Strong Password Policies:<\/strong> Require complex passwords and regular password changes.<\/li>\n
        • Limit sudo Access:<\/strong> Grant administrative privileges only to users who absolutely need them.<\/li>\n<\/ul>\n

          5. Monitoring & Logging<\/strong><\/h3>\n
            \n
          • Enable System Logging:<\/strong> Make sure syslog or journald is active and storing logs.<\/li>\n
          • Monitor Logs:<\/strong> Use tools like Logwatch or set up log monitoring\/alerting for suspicious activity.<\/li>\n
          • Set Up Intrusion Detection:<\/strong> Consider tools like AIDE or OSSEC for file integrity monitoring.<\/li>\n<\/ul>\n

            6. Backups & Disaster Recovery<\/strong><\/h3>\n
              \n
            • Schedule Regular Backups:<\/strong> Back up data and configs regularly, and store copies off-site or in the cloud.<\/li>\n
            • Test Restores:<\/strong> Periodically test your backups to ensure they\u2019re working and restorable.<\/li>\n<\/ul>\n

              7. Physical Security<\/strong><\/h3>\n
                \n
              • Restrict Physical Access:<\/strong> If you manage the server hardware, make sure it\u2019s in a secure, access-controlled environment.<\/li>\n<\/ul>\n

                8. Ongoing Maintenance<\/strong><\/h3>\n
                  \n
                • Review Security Policies:<\/strong> Update your security policies as threats evolve.<\/li>\n
                • Train Staff:<\/strong> Make sure anyone with access understands security best practices.<\/li>\n<\/ul>\n
                  \n

                  Pro tip:<\/strong> Security isn\u2019t a \u201cset it and forget it\u201d deal\u2014it\u2019s an ongoing process. Scheduling regular maintenance and reviews is just as important as the initial setup.<\/p>\n","protected":false},"excerpt":{"rendered":"
