How do you detect, prevent, and manage DDoS attacks and application-level attacks?
To prevent Distributed Denial of Service attacks, I use remote website protection http://v-sys.org/services/ddos_protection/remote_site_protection . It`s really effective!
There are special tools and software to prevent DDoS attacks, one can find them easily in the web. As for me, I use http://stop-ddos.net/en/prices.html , very reliable guys, never let me down. I run some business which has powerful online support, so that services like that are just irreplaceable for my succesful work.
Preemptive protection against DDoS attacks is difficult, because we have no way of knowing when, where, or what type to expect. Also, please note that AppNexus does not manage nor monitor the customer’s applications (even their OS). That said, in the event of an attack the use of Cisco ACLs allows us to apply deny statements for the source of the attack without affecting performance of the rest of the network. Also, we highly recommend that our customers utilize the F5 server load balancing technology for front-ending their web applications, as the F5s provide built-in DDoS protection when it performs full-proxy session offload.
