A Denial of Service (DoS) attack is a cyber-attack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users. This is typically accomplished by flooding the target with traffic or sending it information that triggers a crash. DoS attacks are often used as a preliminary step to more sophisticated attacks, such as distributed denial of service (DDoS) attacks, which involve multiple compromised systems flooding the targeted machine or network with traffic.

DoS attacks can be classified into several types based on the method used to disrupt the service. Some common types include:

1. Network-level attacks: These attacks target the network infrastructure, such as routers and switches, to disrupt the flow of traffic.

2. Application-level attacks: These attacks target specific applications or services, such as web servers, to overwhelm them with requests.

3. Protocol attacks: These attacks exploit vulnerabilities in network protocols, such as TCP, to disrupt communication.

DoS attacks can have significant impacts on businesses and individuals, including financial losses, reputational damage, and disruption of services. To mitigate the risk of DoS attacks, organizations can implement various security measures, such as firewalls, intrusion detection systems, and traffic filtering. Additionally, using redundant systems and services can help ensure that critical functions remain available even if one system is compromised.
