- Use
firewalld<\/code> for Dynamic Management<\/strong>: On CentOS, use sudo firewall-cmd --add-port=8080\/tcp --permanent<\/code> for flexible configurations.<\/li>\n\n\n\n- Monitor Traffic<\/strong>: Enable logging in
ufw<\/code> or iptables<\/code> to track suspicious activity: sudo ufw logging on<\/code>.<\/li>\n\n\n\n- Automate Security<\/strong>: Install
fail2ban<\/code> to block brute-force attacks on open ports: sudo apt-get install fail2ban<\/code>.<\/li>\n\n\n\n- Audit Ports Regularly<\/strong>: Use
sudo nmap -sS yourserverip<\/code> to scan for unintended open ports.<\/li>\n\n\n\n- Secure SSH<\/strong>: Change the default SSH port (22) to a custom port (e.g., 2222) and use key-based authentication:
sudo nano \/etc\/ssh\/sshd_config<\/code>.<\/li>\n\n\n\n- Backup Rules<\/strong>: Save firewall configurations with
sudo ufw status > firewall_backup.txt<\/code> to restore settings if needed.<\/li>\n<\/ul>\n\n\n\nXenax Cloud\u2019s infrastructure ensures these practices are secure and efficient.<\/p>\n\n\n\n
