The target website, system, or network is flooded with traffic that exceeds the server’s capacity in a distributed denial-of-service attack. The goal is to prevent the server/website from being accessed by the intended users. DDoS can occur in one of two ways:
Flooding attacks are the most prevalent form of DDoS attack. Flooding assaults bring the system to a halt when the server becomes overwhelmed with traffic it can’t manage. With the aid of automated software, the attacker delivers packets in a constant stream.
This is the least prevalent type of DDoS assault, in which the attacker takes advantage of a flaw in the targeted system to crash it. It restricts genuine users’ access to email, webpages, banking accounts, and gaming websites.
To avoid a DDoS attack, you must:
- Configure firewalls and routers
- Recognize the spike in traffic
- Consider front-end hardware
- Empower the server with scalability and load balancing
- Use anti-DDoS software
