IoT has the potential to make 'serverless' even bigger.
We'll be delivering a steady stream of news, interviews and behind-the-scenes scoops.
This is among the largest rounds of funding we have seen since the beginning of 2016.
Distributed Denial of Service is a big deal—huge pools of Internet of Things (IoT) devices, such as security cameras, are compromised by botnets and being used for large scale DDoS attacks. What are the tools in hand to fend these attacks off? The first misconception is that you can actually fend off a DDoS attack. There is no magical tool you can deploy that will allow you to go to sleep every night thinking, “tonight my network will not be impacted by a DDoS attack.” There are tools and services that deploy various mechanisms that will do the engineering and work for you, but there is no solution for DDoS attacks.
One such reaction tool is spreading the attack. In the network below, the network under attack has six entry points.
Assume the attacker has IoT devices scattered throughout AS65002 which they are using to launch an attack. Due to policies within AS65002, the DDoS attack streams are being forwarded into AS65001, and thence to A and B. It would be easy to shut these two links down, forcing the traffic to disperse across five entries rather than two (B, C, D, E, and F). By splitting the Continue reading
