Distributed Denial-of-service attacks decreased slightly in 2021 but are becoming larger and more complex in nature, an analysis from F5 has found.

"The volume of DDoS attacks has fluctuated by quarter, but the unmistakable trend is that these attacks are getting larger," said David Warburton, Director of F5 Labs.

Volumetric attacks, which use publicly available tools and services to flood a target's network with more bandwidth than it can handle, continued to be the most common form of DDoS in 2021, comprising 59% of all recorded attacks.

27% of attacks in 2021 harnessed TCP, up from 17% the previous year, and indicative of the requirements of more complex application and protocol-based attacks.

Banking, financial services and insurance was the industry most targeted by DDoS attacks in 2021, subjected to more than a quarter of the total volume.

"As the sophistication and variety of DDoS attacks increases, organizations will find themselves using a wide variety of measures to protect against them, including upstream controls to inspect and limit the traffic reaching endpoints, and managed service providers who can work alongside internal security teams both to prevent attacks and move quickly to mitigate those in progress."
