One of the hot topics of the moment on the Radix Discord and Telegram (https://discord.gg/WkB2USt , https://t.me/radix_dlt) is the subject of DDoS and how Validator node runners can mitigate against such a threat.
Whilst there are a multitude of ways in which a malicious actor could try to bring down or take control of the Radix network, one of the most common and easiest to implement is a DDoS attack.
A DDos attack, or Distributed Denial of Service, is an attempt to overload a machine or server by flooding it with traffic, or exhausting it's resources so that it is unable to provide it's regular service to normal users. To make matters worse, a "Distributed" DoS attack can come from a multitude of sources simultatenously, making it increasingly difficult to block. At Radstakes we utilise brute-force protection on our nodes to prevent attacks from individual sources, but to cope with an orchestrated or bot driven DDoS attack, we acknowledge the need to offer more protection for the good of the network and that of our stakers.
"Radstakes endevaour to only host our nodes with cloud infrastructure that provide DDoS protection. This provides us up to 10Gbps of bandwidth to mitigate DDoS attacks and re-route malicious activity within approximately 60 seconds."
This protection, coupled with our high availability strategy of operating a backup Validator with a separate provider, aims to provide our stakers with the reassurance that in the event of any attack or downtime, we can be back up and validating as soon as possible.
Whilst there are no guarantees, our stakers can rest assured that DDoS protection will always be a part of our commitment to ensuring the security of the Radix network, as well as maximising your staking rewards!
