When dealing with a VIP address of a WAF-protected domain name being blocked due to DDoS attacks, several strategies can be employed:
**1. Implement DDoS Protection Services:
- Utilize advanced DDoS protection services that can detect and mitigate large-scale attacks before they impact your VIP address.
- Example: Tencent Cloud's Anti-DDoS Pro service provides real-time monitoring and automatic mitigation of DDoS attacks, ensuring the availability of your services.
**2. Configure Rate Limiting:
- Set up rate limiting rules to restrict the number of requests from a single IP address or network within a specified time frame.
- This helps prevent excessive traffic from overwhelming the VIP address.
**3. Use a Content Delivery Network (CDN):
- Deploy a CDN to distribute traffic across multiple servers and geographically dispersed locations.
- This not only helps absorb DDoS attacks but also improves the performance of your website.
- Example: Tencent Cloud's Cloud Front CDN service can be integrated with WAF to enhance security and performance.
**4. Modify Firewall Rules:
- Adjust firewall settings to block suspicious traffic patterns and known malicious IP addresses.
- Regularly update these rules to adapt to new threats.
**5. Engage with the Cloud Provider:
- Work closely with your cloud service provider to report the issue and seek assistance.
- They may have additional tools or resources to help mitigate the attack and restore service.
**6. Implement IP Rotation:
- Rotate VIP addresses periodically to distribute the risk and make it harder for attackers to target a single point.
- This can be done manually or through automated scripts.
**7. Monitor and Analyze Traffic:
- Continuously monitor network traffic to identify unusual patterns or spikes that could indicate an attack.
- Use analytics tools to gain insights into traffic sources and types, aiding in proactive defense.
By combining these strategies, you can effectively manage and mitigate the impact of DDoS attacks on your WAF-protected domain's VIP address.
