Non-flood/non-volumetric Distributed Denial of Service (DDoS)
Over the last two decades, both Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks have been growing in frequency, complexity and volume.
Traditionally, these attacks are associated with botnets and large amounts of traffic aimed at disrupting Internet-facing services. However, while the goal of these attacks remains the same, the variety and complexity has evolved and coupled with the increase of available network speeds, these attacks are a growing threat.
This whitepaper aims to provide an overview of non-volumetric DDoS attacks, addressing the techniques used to carry out such attacks and the defences or mitigations needed to improve system resilience when under attack.
