1. DDoS Protection
Understanding DDoS Attacks
A Distributed Denial of Service (DDoS) attack is a malicious attempt to disrupt the normal functioning of a targeted server, service, or network by overwhelming it with a flood of internet traffic. In simpler terms, imagine a group of people trying to enter a small store all at once; the store becomes overwhelmed and can’t serve its regular customers. DDoS attacks can come from various sources, including botnets, which are networks of infected computers that can be controlled remotely to send massive amounts of traffic to a target.
These attacks can lead to significant downtime, loss of revenue, and damage to a company’s reputation. For businesses that rely heavily on their online presence, a DDoS attack can be devastating. Understanding the nature of these attacks is crucial for implementing effective security measures.
