These are the most common type of DDoS attacks. They overwhelm the target's system by sending a high volume of requests to access the site or service. For these attack types, attackers focus on the server that the site or service is running on.

These attacks use large volumes of data to flood your website's bandwidth and ground the server due to a lack of available space.

Volumetric attacks manifest commonly as DNS amplification, where hackers use bots to request information, thus taking up large data amounts. 

Protocol attacks occur when attackers target parts of your system and send tons of requests from all directions.

The most effective way of preventing DDoS attacks from bringing your business down is by distributing your resources to multiple locations. That way, it will be difficult for attackers to target your whole business.

Monitor your website traffic and have an accurate idea of how your website traffic looks like on a typical day. This will help you spot DDoS attacks early enough and mitigate the problem before it cripples your services.

Configure firewalls and routers in the right way to help in deflecting potentially dangerous traffic. Firewalls and routers then analyze, identify, and block the traffic before it 

You can also use DDoS mitigation services to protect your network from DDoS attacks. Radware, Akamai, and Cloudflare are some of the service providers that help in preventing DDoS attacks.
