Protecting the network from reduced bandwidth
Friends, we continue sorting different types of risks that could potentially disrupt the work of #MetaHash, as well as the ways to protect against them. Last time we discussed the threat of the Nodes failure in service, and today we are offering to explore attacks that reduce network bandwidth.
Experts from Georgetown University and the U.S. AFRL found out that, for example, the performance of Tor, an anonymous network, can be reduced by three types of targeted DDoS attacks, reducing system bandwidth and users loyalty. The first technique involves attacking the relayed Tor nodes, not every server. The second method attacks the TorFlow load-balancing system. The third type presumes a DDoS attack on Tor relays, basic servers that transfer traffic to each other to ensure anonymity in this network.
Although these attacks cannot cause a serious failure or completely block the system, they can permanently degrade its performance, making users stop working. As you can see, providing protection against these types of threats is critical to both the network and the community.
Network bandwidth, DDoS attack via multiple transaction generations
Risk type: Operational.
Probability: Low. Unlike the DDoS type in the previous risk, this attack requires much larger computational resources from the attacker, hence makes it an even more costly operation in comparison to the previous risk.
Consequences: Low.
Risk Control: During high network load transaction fees start growing nonlinearly, thus, attack quickly becomes impractical. With trying to maintain the 20% network load such an attack would cost $2,000 each second. With 80% load, one transaction would cost $3.91 at ICO price and the attack would cost $200,000 per second. Thus, such an attack can increase transaction prices in the network only for a short span of time.
Next time we will talk about methods of protecting the network from other types of attacks, particularly, DDoS attacks on blocks, which reduces the network bandwidth.
