Distributed Denial of Service (DDoS) is a malicious attack aimed at disrupting the normal functioning of a targeted server, service, or network by overwhelming it with a flood of internet traffic. DDoS attacks typically involve multiple compromised devices, making it challenging to mitigate. Such attacks can lead to service outages, financial losses, and damage to reputation. Organizations implement various security measures, such as traffic filtering and load balancing, to protect against DDoS attacks and maintain service availability.
