Distributed denial-of-service (DDoS) attacks are more complex and cause more financial damage than ever, new data shows.
According to NETSCOUT Arbor’s 2017 Worldwide Infrastructure Security Report published on Wednesday, the number of DDoS attacks that cost organization between $501 to $1,000 per minute in downtime increased by 60%. In addition, 10% of enterprises estimated a major DDoS attack cost them greater than $100,000 in 2017, five times more than previously seen. Now in its 13th year, the report is based on 390 responses from service providers, hosting, mobile, enterprise, and other types of network operators from around the world. A full 66% of all respondents identify as security, network, or operations professionals.
Gary Sockrider, principal security technologist with NETSCOUT Arbor, says there was a 20% increase in multi-vector attacks in 2017 compared to the previous year. Multi-vector attacks combine high-volume floods, TCP state exhaustion attacks, and application-layer attacks in a single sustained offensive, which makes the attacks more difficult to mitigate and increases the attackers chance of success.
