What Is A DDoS Attack?

A Distributed Denial of Service (DDoS) attack is an attack that targets the normal traffic of a web server or network.

DDoS attacks work by overwhelming the server with internet requests. This ultimately causes the server to be unavailable for actual users.

Which Is The Best Tool For A DDoS Attack?

The best tool for protecting your website from a DDoS attack is SolarWinds’ Security Event Manager (SEM).

It prevents the DDoS attack from happening and responds automatically to the attack.

What Are DDoS Attack Tools?

DDoS attack tools are used to either simulate a DDoS attack or protect from it. Some tools simulate Denial of Service attacks so that you can test your web server against them.

Others provide protective functionality as well as investigative benefits.

What Are the Types of DDoS Attacks?

DoS and DDoS attacks are of 3 types: volume-based, protocol, and application-layer attacks.

Volume-based attacks overwhelm the server’s bandwidth and are measured in bits per second.

Protocol attacks consume server resources or firewalls and load balancers. Finally, application-layer attacks aim to crash the server with multiple requests.


Protecting your website against DDoS attacks is a need of modern times.

However, your web server could be at risk if you’re not prepared against a Denial-of-Service attack.

Without even a basic level of security, your server will crash instantly. 

But how do you know if your web server can withstand DoS or DDoS attacks?

Luckily, some tools are available online that let you simulate such attacks.

Other tools work by providing protective measures against the attacks. And they let you investigate further. 

These were just a few of the free DDoS attack tools that are available for you to use to protect your website. You can surely find the right tool for yourself here.
