CloudFlare protects millions of websites from online threats. One of the oldest and most pervasive attacks launched against websites is the Distributed Denial of Service (DDoS) attack. In a typical DDoS attack, an attacker causes a large number of computers to send data to a server, overwhelming its capacity and preventing legitimate users from accessing it.
In this blog post, we’ll go over how attackers have been using malicious sites, server hijacking, and man-in-the-middle attacks to launch DDoS attacks. We’ll also describe how to protect your site from being used in these attacks by using HTTPS and an upcoming web technology called Subresource Integrity (SRI).
