attack and how is it different from DDoS?<\/h2><p>A <strong>denial-of-service (DoS)<\/strong> attack aims to take your service offline by flooding the server with more requests or connections than it can handle. Some attacks need just one machine, like Slowloris, which opens many connections and keeps them hanging until the web server is full.<\/p><p>A <strong>DDoS<\/strong> attack is distributed, coming from thousands of machines at once, often botnets. Attacks are not limited to websites over HTTP; they can target other services such as SSH, FTP and email.<\/p><\/div><div class=\"hy-tldr\"><p><strong>In short:<\/strong> A DoS attack floods the server from one or a few sources, while DDoS comes from thousands of machines.
