Teenusetõkestusrünne

Teenusetõkestusrünne, often referred to as a Denial-of-Service (DoS) attack or Distributed Denial-of-Service (DDoS) attack, is a malicious attempt to disrupt the normal traffic of a targeted server, service, or network by overwhelming the target or its surrounding infrastructure with a flood of internet traffic. The goal is to make the target resource unavailable to its intended users.

DoS attacks can be launched from a single source, while DDoS attacks utilize multiple compromised computer systems, often referred to as a botnet, to launch the attack. These compromised systems can be anywhere in the world and are controlled remotely by the attacker. The sheer volume of traffic generated by a DDoS attack can overwhelm the capacity of the target system's network connection or processing power, leading to a slowdown or complete shutdown.

The impact of a successful denial-of-service attack can range from minor inconvenience to significant financial loss and reputational damage. For businesses, this can mean lost revenue due to an inaccessible website or online service, as well as the cost of mitigation and recovery efforts. For individuals, it might mean being unable to access online banking, social media, or other essential services.

Various methods can be employed to carry out these attacks, including exploiting vulnerabilities in network protocols, overwhelming a server with connection requests, or flooding a network with excessive data. Defending against these attacks often involves a combination of network security measures, traffic filtering, and specialized DDoS mitigation services. These services work by detecting and blocking malicious traffic before it reaches the target.
