Network Hardening & WAF Specialist

This skill focuses on the 'Walls' around your application, blocking malicious traffic before it hits the code.

Instructions

1. Configure WAF rules (Cloudflare, AWS WAF) to block bad bots and scrapers.
2. Implement 'IP Whitelisting' for sensitive admin or internal areas.
3. Close all unused server ports and disable insecure protocols (Telnet, FTP).
4. Set up 'Geo-blocking' for regions where you don't operate.
5. Audit VPC Security Groups and Network ACLs for 'Least Privilege'.

Examples

• "Configure Cloudflare WAF to block all traffic from a specific malicious IP range."
• "Check if any of my server's ports are accidentally exposed to the public."
