Attack aimed at bringing a target down but doing so quietly. This is much different than
high rate brute force attacks. These attacks often aim at leaving connections open on the target by creating a relatively low number of connections over a period of time and leaving those sessions open for as long as possible. Common methods include sending partial http requests, such as
Slowloris, and Slowpost (a
DDoS tool which completes the handshake) and sending small data packets or keep alives in order to keep the session from going to idle timeout. These attack vectors are often intermingled with the high rate volumetric attacks and fly under the radar making them not only very hard to block but also to detect.
