Alternatives to those below:
- SolarWinds
It is an effective mitigation and prevention software to stop DDoS attacks.
- HULK
It generates unique and obscure traffic
- Tor's Hammer
Apache & IIS server
- Slowloris
Send authorized HTTP traffic to the server
- LOIC
UDP, TCP, and HTTP requests to the server
- XOIC
DoS attack with TCP or HTTP or UDP or ICMP message
So bottom line, its all a matter how you prevent and "combat" the attack and maintain your server protected, the simple option to block incoming attacks from a IP address can also work well. Attackers always start by looking into your server breaches within folders named as admin, config, etc.
