Not surprisingly, cloud companies usually don't want to discuss attacks on their networks. When one does disclose information, it offers rare insight into the scale of attacks against companies every day.
Richardson, Texas-based FireHost, a cloud hosting company, blocked more than 64 million attacks last year, according to Chris Hinkley, senior security architect.
Most of those attacks were directed at FireHost clients; the attackers may not have known they were targeting servers managed by a cloud service. Nevertheless, attacks on FireHost itself are growing, Hinkley said, a sign that hackers are starting to see the value in attacking cloud providers directly.
