Introduction
Multiple infected computer systems attack a target and cause a denial of service for users of the targeted resource in a distributed denial-of-service (DDoS) assault. A server, website, or other network resources could be the target.
DDoS assaults can affect any publicly accessible website, and WordPress-based sites are no exception. Thankfully, WordPress is a fairly adaptable platform. It is just a matter of forewarning: to resist or lessen the impacts of an attack, you must act before it occurs.

Prevention of the DDOS Attacks
The two security procedures you must take to safeguard your WordPress site from DDoS assaults are as follows:

  • Get a reliable backup solution for WordPress.
  • Begin by implementing a low-cost, cloud-based anti-DDoS security solution.
  • Following we have given three approach guidelines regarding how to protect your WordPress from DDOS attacks:
