DDoS Attacks Are in Decline in Number and Size, Akamai Report Finds

In the security world, there tends to be a constant stream of news about how the number of attacks is increasing, which is what makes Akamai's "First Quarter, 2017 State of the Internet/Security Report" interesting. According to the report, there was a 30 percent year-over-year decrease in the total number of distributed denial-of-service (DDoS) attacks in 1Q17. Going a step further, there was an 89 percent decrease in the number of DDoS attacks greater than 100G bps. The report isn't all good news, though: In the first quarter of 2017, there was a 35 percent increase in the total number of web application attacks, with SQL injection attacks leading the way. In this slide show, eWEEK looks at the highlights from the most recent Akamai State of the Internet/Security Report.

Majority of DDoS Attacks Use Reflection

The majority (57 percent) of DDoS attacks do not just rely on direct bandwidth to attack victims. Rather, they rely on some form of misconfigured internet service to "reflect" an attack, in effect amplifying the total attack bandwidth.
