Ethereum: Protection against attacking of service denial (back)
One of the most urgent concerns of cryptocurrency technology and blockchain is the most urgent concerns of the Ministry of Service (Back). The purpose of these malicious activities is to interfere with or build an inoperable network by crushing them with excessive amounts of traffic or data. In this article, we are immersed in the defense that Ethereum provides against back attacks and reveal that it is possible to have a knot through such tactics.
What is the denial (back) of the service?
The service of the service (BACK) is an attempt to not be achieved with computer or network resources, crushing traffic, data or requests. This is deliberately done or not, and in general the goal is to disrupt services, steal sensitive information or export money.
What Bitcoin protection is Bitcoin in the back attacks?
The decentralized nature of Bitcoin provides multilayer protection against back attacks:
- IP Addresses: Each bitcoin node has a single IP address that makes the attacker difficult to flood a particular traffic node.
- Network Topology : The Bitcoin network is designed as a peer network (P2P) where the nodes communicate directly. It is difficult to target several nodes at a time.
- Consensus Mechanism : Bitcoin consensus algorithm guarantees that all nodes are the same as blockchain. If a node is overloaded, others can set their transactions and synchronize complete collapse.
Can you cut a node by flooded with data?
Yes, it is theoretically possible to cause the Bitcoin node problems through excessive data transfer. However, this requires huge traffic, which can potentially flood the network infrastructure.
Assuming a malicious actor had to flood a huge amount of data a knot, for example:
- Access 1 Exubite (10 ^ 19 bytes) per second
- Cover each IP addresses on the Internet
It is unlikely that it would always cause significant disturbances. The Bitcoin network is designed to manage these fees without collapse.
What happens when someone is legitimate but starts to flood the network with absurd data?
Flood attacks are a type of rear attack where the attacker injects false or insignificant traffic towards the network. This can happen for a variety of reasons:
* Spambrots
: Malicious scripts that flood the SPAM data network to distribute malicious programs or steal sensitive information.
* Virus infections : Deployment of nodes, causing a significant increase in traffic.
To destroy the back attacks
To protect back attacks against Bitcoin and Ethereum:
- Use strong antivirus software : Regularly scan your systems for viruses and malicious programs.
- Execution of firewalls and penetration systems : Configure the network to block suspicious traffic.
- Refresh the nodes Regularly: Keep operating systems, nodes wallets and other software to correct all vulnerabilities.
In summary, although the decentralized nature of Bitcoin provides some protection against back attacks, this is not infallible. The landscape of the threats further develops and it is essential to continue to find out about the latest security measures and the best practice of protecting digital devices.
