Elastic Stack Elasticsearch

Hi,

We are using ELK 6.2.4 stack, is there a Overload control mechanism to reduce the impact of DoS attacks?
If yes, can you please let us know what is the mechanism.

Thanks & Regards,
Mahesh

Is the implication here that you are exposing Elasticsearch to the internet, and you want to protect it from DoS attacks via the internet?

Hi,
We are not directly exposing Elasticsearch and kibana to the internet. the ports are behind the firewall.

Then isn't it the job of the firewall to protect against DoS?
