Distributed Denial of Service (DDoS) Attack

A Distributed Denial of Service (DDoS) attack is a malicious attempt to disrupt a website, server, or network by overwhelming it with a flood of artificial traffic. This results in websites being overloaded and unresponsive to legitimate requests. The best way to protect your website against DDoS attacks is to choose a reliable web hosting provider with robust firewalls.
