Link to article What are DoS and DDoS attacks?
A denial of service attack aims to disable the use of a system, application or machine in order to block the service for which it is intended. This attack can affect both the source that provides the information, such as an application or the transmission channel, and the computer network.
connections simultaneously. If this number is canada phone number data exceeded, the server begins to slow down or may even fail to respond to requests or may even crash and disconnect from the network.
There are two techniques for this type of attack: denial of service or DoS (Denial of Service) and distributed denial of service or DDoS (Distributed Denial of Service). The difference between the two is the number of computers or IPs that carry out the attack.
In DoS attacks, a massive number of requests to the service are generated from the same machine or IP address, thus consuming the resources offered by the service until a point is reached when it has no response capacity and begins to reject requests; this is when the denial of service materializes.
In the case of DDoS attacks, requests or connections are made using a large number of computers or IP addresses. These requests are all made at the same time and to the same service that is the target of the attack. A DDoS attack is more difficult to detect, since the number of requests comes from different IPs and the administrator cannot block the IP that is making the requests, as is the case in a DoS attack.
Computers that carry out DDoS attacks are recruited by malware infection, thus becoming bots or zombies, capable of being controlled remotely by a cybercriminal. A set of bots, that is, computers infected by the same malware, form a botnet, also known as a zombie network. Obviously, this network has a greater capacity to take down servers than an attack carried out by just one machine.
Distributed Denial of Service Attack
To check if our computer is infected by this type of malware and belongs to a zombie network, without us being aware, we can use the AntiBotnet service that will detect if our network belongs to a botnet.
Why are these attacks carried out and who do they affect?
As we have seen, denial of service attacks are used to disable a service offered by a server, causing the system to collapse by taking advantage of its vulnerabilities. The objective of cybercriminals is to cause harm to both the users who use the service and the administrator who offers it, disabling its functionality and causing losses, both financial and in reputation.
So far, the largest denial of service attack in history occurred on February 28, 2018, against a well-known collaborative project platform. The platform was left inoperative for about 10 minutes in total, intermittently. This attack was carried out in a distributed manner, that is, with a DDoS attack. Despite all the security available to the platform, it could not cope with the bombardment of 126.9 million packets or, in other words, about 1.35 terabits per second received. This attack was carried out through a botnet network using servers from various entities.
