Cloudflare Images | DDOS
We switched from Cloudflare R2 to Cloudflare Images a few days ago, and Cloudflare Documentation says it charges me $1 for each 100,000 successful deliveries. What if I get a DDoS attack? Does Cloudflare have a DDoS mitigation system for images, or should I manually configure Cloudflare somehow?

Cloudflare does have built-in DDoS mitigation systems that are designed to protect your entire website, including any content delivered through Cloudflare Images. These protections are automatically applied, and you don't need to manually configure them specifically for Cloudflare Images.
However, there are a few steps you can take to enhance your security and manage costs in case of a DDoS attack:
1. Rate Limiting:
Implement rate limiting rules in Cloudflare to limit the number of requests from a single IP address. This helps prevent malicious users from overwhelming your resources.
Go to your Cloudflare dashboard > Security > Bots > Rate Limiting and configure rules based on your expected traffic patterns.
2. Bot Management:
Enable Cloudflare's bot management features to distinguish between legitimate and malicious traffic. This can help reduce unwanted traffic to your Cloudflare Images.
Configure bot management under Security > Bots in the Cloudflare dashboard.
3. Firewall Rules:
Set up custom firewall rules to block or challenge requests based on specific patterns that match known attack vectors.
Access this by navigating to Security > WAF > Firewall Rules in your Cloudflare dashboard.
4. Caching:
Ensure that your images are properly cached to reduce the load on your origin server and minimize the number of requests counted against your Cloudflare Images quota.
You can configure this under Caching > Configuration in the Cloudflare dashboard.
5. Alerting and Monitoring:
Set up alerts and monitor traffic patterns so you can quickly detect and respond to abnormal traffic spikes that could indicate a DDoS attack.
You can configure this under Analytics & Logs in the Cloudflare dashboard.
6. Usage Notifications:
To avoid unexpected charges, set up usage notifications to alert you when you approach your usage limits.
By using these tools, you can better protect your site and manage traffic, ensuring that DDoS attacks don't lead to unexpectedly high charges.
