How is a DDoS executed against a website?
A website DDoS is executed by flooding one or more of the site’s web servers with so many requests that it becomes unavailable for normal use. If an innocent user makes normal page requests during a DDoS attack, the requests may fail completely, or the pages may download so slowly as to make the website unusable. DDoS attacks typically take advantage of several computers which simultaneously launch hundreds of thousands of requests at the target website. In order not to be traced, the perpetrators will break into unsecured computers on the internet, hide rogue DDoS programs on them, and then use them as unwitting accomplices to anonymously launch the attack.
