What is DDoS attack?

An attack on a distributed denial of service (DDoS) is a malicious attempt to interfere with the normal traffic of a targeted server, service or network by overwhelming the target or its surrounding infrastructure with a flood of Internet traffic.

By using multiple compromised computer systems as sources of attack traffic, DDoS attacks achieve efficiency. Computers and other networked resources such as IoT devices can be included in exploited machines. A DDoS attack from a high level is like a traffic jam blocking the road to prevent regular traffic from reaching its desired destination.

How does a DDoS attack work?

In order to carry out an attack, a DDoS attack requires an attacker to gain control of an online machine network. Computers and other machines (such as IoT devices) are malware-infected, each turning into a bot (or zombie). The attacker then controls the bots group remotely, which is called a botnet.

Once a botnet has been set up, the attacker can direct the machines via a remote control method by sending updated instructions to each bot. If the victim’s IP address is targeted by the botnet, each bot will respond by sending requests to the target, which may cause the targeted server or network to overflow, leading to a denial of service to normal traffic. Since each bot is a legitimate Internet device, it can be difficult to separate attack traffic from normal traffic.

2. Microsoft Azure

Microsoft AzureAzure DDoS protection, combined with best practices in the design of applications, offers protection against DDoS attacks.

The DDoS Protection Standard monitors the actual use of traffic and constantly compares it to the DDoS policy thresholds. If the traffic threshold is exceeded, DDoS mitigation is automatically initiated. The mitigation is removed when traffic returns below the threshold.

Special Feature:

  • Monitoring and automatic mitigation of network attacks
  • Integration for analytics and insights with the Azure Monitor
  • Protection of the application layer with Azure Application Gateway Web Application Firewall
  • Protection from unforeseen costs of an attack by DDoS
