Cloud service providers (CSPs) continue to power a growing portion of the greater Internet. According to Cisco, by 2021, 73 percent of cloud workloads are going to be CSP based, which reflects a compound annual growth rate of 27.5 percent from 2016 to 2021.
Unfortunately, CSPs are vulnerable to both Account Takeover (ATO) attacks and free account trial abuses that nefarious botnets exploit to their advantage. Akamai sees in upwards of 30 DDoS attacks per day with CSPs amongst the top traffic sourced ASNs.
