What are DDoS attacks?

The abbreviation DDoS stands for Distributed Denial Of Service. A DDoS attack is a type of DoS attack in which several hijacked systems are used to carry out an attack against the target system. This is the difference from the traditional DoS attack, in which the attack is carried out only from a single system.
Due to the number of excessive requests, it is difficult to identify or block each individual attacker via an IP address. High computing capacities allow cybercriminals to execute server requests in a much shorter time. The infiltrated bot network alone, which coordinates the attacks, ensures this. The computer systems illegally brought under the attacker's control receive corresponding commands via this path. The attacker uses a Trojan for this purpose. The bot network is controlled via this Trojan. A possible target for a DDoS attack is, for example, a company's mail server.

DDoS attack - procedure

Interference with data traffic by sending unauthorized data packets with a huge volume of data. The processing of conventional requests may no longer be possible. The mass transmission of data creates a veritable flood of data. This form of DDoS attack can have an impact on the bandwidth used by the target system. The data responsible for bandwidth drops is also referred to in English as "junk data". The impact ranges from a small limitation to a complete failure of network as well as device resources. Attacks on applications are carried out using specifically constructed data packets tailored to the attack target. As a result of the DDoS attack, the services can no longer be accessed, or only to a limited extent.
