Akamai has published its Q4 2016 State of the Internet/Security report As always, an interesting read and an opportunity to look at trends in attacks.
Not all trends are up and to the right. As the report states, Q4 2016 was "the third consecutive quarter where we noticed a decrease in the number of attack triggers". Still, "the overall 2016 attack count was up 4% as compared to 2015". Also, the volume and number of "mega-attacks" is on the rise.
