Note: This method of mitigating attacks can be challenging as you’ll need to identify malicious signatures or accurately distinguish malicious IP addresses. Scale up HA proxy servers and increase S3 storage capacity to increase data logging. The basic premise of any DDoS attack is to generate so much “junk” network traffic for a particular system that it causes the target – such as a corporate website or network – to crash or halt operations. This rearranges certain services and immediately stops the flow of traffic to those IP addresses. In a message sent out to clients, for example, it simply noted, “Our DDoS mitigations are absorbing the vast majority of this traffic, but they are also flagging some legitimate customer queries at this time.” You can set up rules proactively to automatically block bad traffic, or respond to incidents as they occur.
