So lets get started.
Is your website behind cloudflare?
If your website is behind cloudflare then skip this step, If its not behind the cloudflare then register your website with cloudflare.
Create a Cloudflare account
- Visit https://dash.cloudflare.com/sign-up.
- Enter your Email address and Password.
- Click Create Account.
- The Cloudflare will asks you to add a site to Cloudflare.
Enter your website’s root domain and then click Add Site. For example, if your website is www.example.com, type example.com.
5. Cloudflare attempts to automatically identify your DNS records. This process takes approximately 60 seconds to complete.
6. Click Confirm in the Confirm Plan window that appears.
7. Review whether all DNS records were identified in the DNS query results window.
To finish domain setup and activate your domain on Cloudflare, change your domain nameservers to Cloudflare.
Replace your current name servers to the cloudflare provided nameservers with your domain
Okay cool, we done setting up nameservers and cloudflare is active. Now lets start Mitigation.
Step 1 : Turn On Under Attack Mode
this is the first step you can use, It will block all the small attacks by adding JS challenge to your website, Its great for blocking layer 3 attacks, all visitors on your website will be show js challenge before entering to your website. This is helpful is most cases.
Step 2 : Checking the IP address from where the ddos attack is coming and blocking them.
On the cloudflare menu, go to firewall Tab and click on Overview.
