SIDN, NBIP warn small businesses of increased risk of DDoS attacks
Small and medium-sized businesses are much more at risk of DDoS attacks than many think, according to research by the Dutch domain registrar SIGN and the internet providers group NBIP. The two groups conducted research on the .nl websites affected by such attacks and the organisations affected. In total, 237 DDoS attacks were identified in the year to June 2018.
Web shops selling consumer goods such as clothes, cosmetics and garden equipment have a bigger chance of being hit by DDoS attacks, the research found. On average the resulting damage costs EUR 1.8 million.
A common cause is the use of shared hosting. To save costs, small online sellers often share a server with other websites. They are then affected if another site on the server is hit by an attack. The chance of collateral damage is 35 times higher in such a case.
The public sector and larger banks remain the most likely target of direct attacks. The study estimates the direct damage cost EUR 59.6 million, while collateral effects cost another EUR 10 million.
The damages are based on the 237 attacks identified and estimates for the consequences if the attacks succeeded. If no protective measures are taken, the total cost to society from DDoS attacks is estimated at EUR 1 billion per year.
