Introduction to DoS and DDos Attack?
Dos Denial of service is a type of cyberattack where someone attacks the server that is exposed over the public internet to distribute the service from working correctly. This will cause temporary unavailability of your service and the users will not be able to use your services. There are various types of denial-of-service attacks present, but most of them want to achieve the same thing.
To stop the service from working in common, denial of service attacks are pretty easy to prevent because you can just block the originating traffic. Hence, instead of using one server, most of the attackers will employ multiple servers to attack your web server in sync. This attack is known distributed denial of service, so-called DDoS.
Azure DDoS Protection
The prevention of a DDOS attack is a means of identifying which server is attacking you and separating them from a legitimate user trying to reach your server. Thus, it only filters the attacker out and yet still allows your user to connect, but this is where Azure DDoS protection comes in.
The scenario happened in Azure, and our web server was hosted on one of the services. Let us say app service, then in front of the Azure App Service, a DDoS protection service would filter the malicious traffic out and let the legitimate user in.
One of the best things about DDoS protection is that the basic plan for DDoS protection comes with all of the Azure services by default, and you don’t pay anything extra. But if you need more protection, then along with the standard plan service, you can create DDoS protection in the Azure portal. It allows you to protect your application from more sophisticated attacks.
Steps for Creating Azure DDoS Protection
- Choose create type DDoS and then enter ok and in the marketplace find DDoS protection plan note this is the standard plan for Azure DDoS protection
- Click create and fill in the form, give the name DDoS protection, select the subscription from the subscription drop-down menu, choose the resource group, and then create a new resource group.
Note: the creation of the plan can take up of less than or 20s time
- Then after successfully creating the DDoS protection plan then, go to the resource and start protecting the Azure resources. When you go to the protected resource section, you will select the add button option for adding the resources to the protection plan. The user will need to choose the resource group that will be protected and then select add all. Thus, all the resources in the network will be protected.
This service is distributed denial of service protection from Microsoft Azure, and it has been designed to do two things detect malicious traffic coming from the attacker and allow the legitimate user to connect the services. Most importantly, to prevent customers from paying more costs if they have auto-scaling environments. In this, the attacker will try to attack your service with hundreds of servers all that traffic might cause the auto-scaling features to create new servers in your application and the user has been paid more as mentioned firstly
Azure DDoS Protection has two types
- Basic type: It is automatically enabled for all of the other services. It means that if the user is using any Azure services already exposed to the public internet could be targeted by a DDoS attack and automatically protected by the default type of Azure DDoS protection.
- Standard type: It provides the additional mitigation and monitoring capabilities for all of the resources which are located within the Azure networks. The best thing about the standard tier also uses machine learning. It is used to analyze the traffic patterns for the application for better accuracy. In general, it is for those the more high-value applications.
Different Types In Denial of Service Attack
- Volumetric DDoS
Volumetric DDoS is by far the most common type of Distributed DoS but the one that creates the most headlines has quantity ever. These attacks overwhelm the networks with attacker-generated traffic. The F5 Operations team mitigates the most prominent attacks in the last 15 days, highest at an imposing 500 Gbps.
- Protocols DDoS attacks work by adding session databases within firewalls or routers, prompting network systems must become inadequate in processing the number of messages being transmitted to them, even though the connection is often not fully utilized.
- Application DDoS attack online are created to overflow the capabilities of the “origin” server, which could be a web, DNS, or another type of application.
Forcing the program to operate illicit requests from the attacker prohibits it from handling legal responses from genuine clients.
DDoS Attack Trends
In the following phase of the last year, distributed denial-of-service (DDoS) attacks approached “peak” levels. The latest Microsoft Azure study on quarter third- and 4th DDoS attack trends. In contrast, Azure’s DDoS defense counsel tries to claim to have defeated the “deadliest attack ever recorded in history.” In November, the firm spotted a DDoS attack targeting Azure customers in Asia with a bandwidth of 3.47 Tbps and a transmission tarrif of 340 thousands a unit of data transfer. These activities aren’t slowing it down. They also appear to be more abundant year-round than simply all-around holidays. Worse, they’re hunting for a wider variety of targets. As per the Azure DDoS mitigation team, the game industry to be the most exposed to DDoS attacks during July and December 2021, accompanied by VoIP and broadband service providers and some others. As per data collected in the second of two halves of 2021, firms in USA and China were most often targeted by HTTP Possible attacks. One in every 200 HTTP requests for US-based firms constituted a DDoS hit.
What are the factors for the rising number and frequency of these attacks? But, again, the Azure professionals have such a quick fix.
“The accessibility of DDoS for hire services, and the cheap costs – at only about $300 per month – make it incredibly simple for anyone to perform aimed DDoS attacks,” researchers conclude.
