Denial of Service (DoS)

An attack that aims to overwhelm a system or network with excessive traffic or requests, causing it to become unavailable to legitimate users. It differs from a DDoS attack in that the attack comes from a single computer.

In a Denial of Service (DoS) attack example, imagine you run an online store. An attacker uses a network of hacked computers to send an enormous amount of fake traffic to your website, overwhelming it. As a result, your website slows down or becomes unavailable to real customers, potentially causing financial losses. To defend against such attacks, businesses use security measures like firewalls and traffic filtering.
