If you have a CDN, does it mean you don't have to worry about DDoS attacks or will hackers still succeed in carrying out DDoS attacks?
I'm a VAR/System Integrator and I don't see any problem once you have Cloudflare.
ISRAEL DIAZ DOMINGUEZCDN is not going to help you to avoid DDoS. The main function of a CDN is to deliver content faster. To mitigate the risk of a DDoS you need a Web Application Firewall (WAF). Todays WAF come with CDN capabilities.
Etienne WEHRLELayer 3 or 4 DDoS are absorbed by the CDN as design (IP, TCP ,UDP), the high volume doesn't reach your origin server so you are automatically protected.
But in case of layer 7 DDoS, all application attacks (SQL injections, XSS, Remote file inclusion), you need a Web Application Firewall (WAF) to protect against this kind of threat, the CDN will not "see" and of course not block these attacks (and it's not his role)
