The function of a DDoS attack is to overwhelm a targeted server or network by flooding it with excessive traffic, rendering it unable to respond to legitimate user requests. This type of cyberattack aims to disrupt the service availability of websites or online services. DDoS stands for Distributed Denial of Service, as the attack is often launched from multiple compromised devices, increasing its effectiveness. These attacks can cause significant downtime, financial losses, and reputational damage for businesses, making it crucial for organizations to implement robust security measures to mitigate such threats.
