Differences between DoS (Denial-of-Service) and DDoS (Distributed Denial-of-Service) in terms of number of attackers, scalability, complexity and defense strategies.**Denial-of-Service (DoS)** and **Distributed Denial-of-Service (DDoS)** are both forms of cyberattacks that aim to prevent access to a network, server, or website by overloading the available resources. Despite their similarities, there are key differences between these two types of attacks: 1. Number of attackers: - DoS (Denial-of-Service): In a DoS attack, the attack is carried out from a single machine or source. The attacker typically uses a single device to flood a website or service with requests, overwhelming the targeted resources. - DDoS (Distributed Denial-of-Service): A DDoS attack, on the other hand, is carried out by several distributed computers or sources simultaneously. These sources are often part of a botnet consisting of many compromised computers. The goal is to achieve an even greater overload of the target through a coordinated flood of requests. 2. Scalability and intensity: - DoS: The scalability of a DoS attack is limited because only one source is involved in the attack. The amount of attacks that a single machine can generate is limited, which often makes the DoS attack easier to defend against. - DDoS: DDoS attacks are much more scalable and intense because they are carried out by many sources simultaneously. This multitude of attack points results in a significantly higher load on the target resources and makes the attack more difficult to mitigate. 3. Complexity: - DoS: Carrying out a DoS attack is often easier because it only requires a single device and method to flood the target resources. - DDoS: DDoS attacks are more complex because they require coordination and management across multiple machines or botnets. Attackers must control and orchestrate the devices involved, which requires more sophisticated and refined technology. 4. Detection and defense strategies: - DoS: Because DoS attacks originate from only one point, it is often easier to identify the attack and take defensive measures, such as IP blocking or rate limiting. - DDoS: DDoS attacks are more difficult to detect and prevent because the attacks originate from many different IP addresses. Effective defenses require specialized solutions such as DDoS protection services and traffic analysis tools to monitor and filter the distribution of traffic. In summary, the main difference between DoS and DDoS is the number of attackers and the scalability of the attack. While DoS attacks originate from a single source and are more limited in intensity, DDoS attacks use a variety of sources to achieve a significantly greater overload of the target resources.
