Big thanks to Akamai and Incapsula for providing the community with a DDoS trends report detailing the specific types of DDoS attacks. The key takeaway is the attacks are getting more sophisticated where attackers launch multi vector attacks to mask certain types of attacks. Multi vector attack simply means two or more types of attacks happening concurrently or one after the other.
The sophisticated DDoS attacks can be classified as advanced persistent threats (APT), since they happen for weeks at a time, and where the attacker shifts the type of attack when one type of attack fails. Akamai and Incapsula provide the number of attacks, types of attacks, and the changing methods attackers use over time on their networks. For Akamai, volumetric DDoS attacks remain the most prevalent, and are used to sometimes cloak smaller but more lethal application layer attacks. Ultimately, the attacker is a highly skilled tactician that enjoys playing minds games, and the Akamai and Incapsula network are his chess board. For the unprepared it will be checkmate in no time. Below is the Akamai and Incapsula DDoS trends report snapshot.
