DDoS attack volumes are on the rise, according to new research. The Q1 DDoS Attack Report from Radware has revealed that while the number of attacks held steady (down 2% from Q4 2020), attack volumes increased by 31% in Q1 2021 vs. Q4 2020. Radware's new quarterly report series, provides an overview of attack activity experienced by a sample of the data security vendor's customers during the first quarter of the calendar year 2021. The report analyses DDoS attack activity by industries, attack vectors, DDoS attacks on applications and on-premise vs. cloud. The largest recorded attack in Q1 of 2021 was 295Gbps, up from 260Gbps in Q4 of 2020. The report found the occurrence of major attacks of 10Gbps or more tripled in Q1 2021 vs. December 2020. While DDoS attacks have traditionally impacted public assets, damaging an organisation's reputation through public exposure, healthcare is different, Radware says.
