Explain the DDoS attack. How to prevent it?

Cyber Security

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:

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.

Crash attacks:

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:

  1. Configure firewalls and routers
  2. Recognize the spike in traffic
  3. Consider front-end hardware
  4. Empower the server with scalability and load balancing
  5. Use anti-DDoS software
