DDoS Attack and its Types!

What is a DDOs attack?

DDoS, or distributed denial of service, is a malicious attempt to make a website or network service unavailable by disrupting the traffic so that it cannot function.

DDoS Attack achieves efficiency by using vulnerable computer systems as sources of traffic attacks. Users may include computers and other network resources such as IoT devices. From a high point, the DDoS attack is like an unexpected traffic jam blocking the highway, preventing normal traffic from reaching our destination.

Types of DDOs Attacks!

Volumetric Attack

The goal of a volumetric attack is to use the botnet to generate a major amount of traffic and clog up the works on the target. Think of it as an HTTP Flood attack, but with an added exponential response component. For example, if you and 30 of your friends all called the same restaurant and ordered 60 plates at the same time, that restaurant will face difficulties and will not be able to fulfil those requests. Volumetric attacks operate on the same principle. They request something from the target that will vastly increase the size of the response, and the amount of traffic explodes and clogs up the server.

DNS Amplification is a kind of volumetric attack. In this case, they are attacking the DNS server directly and requesting a large amount of data back from the DNS server, which can bring the DNS server down and cripple anyone that is using that DNS server for name resolution services.

Protocol Attack

Attack of the DDoS Protocol targeted a network layer of targeted systems. Their goal is to cover the tablespaces for the main network services, firewall, or loading relay that transmits applications to the target.

Typically, network resources operate in a first-line. The first application comes in, the computer processes the request, and then it goes and finds the next application online, and so on. There are now a limited number of locations on this line, and in a DDoS attack, the queue may be so large that there are no computer resources to handle the initial request.

Application layer attack

The DDoS attack of the program layer is intended to exploit the services of the target and disrupt access to the targeted website or service. Attackers load the bots with a sophisticated application that taxes the targeted server as it tries to respond. The application may require access to a website or a large download. If the target receives a few million of those requests in a short period of time, it can be quickly frustrated and reduced to clarity or completely shut down.

HTTP Flood Attack, for example, is a web application attack that targeted the webserver and targeted many HTTP applications to slow down the server. Think of it as pressing the refresh button on the fire mode immediately in your game controller. That kind of traffic from many thousands of computers at once will quickly drown a web server.

In today’s cyber world, denial of service attacks is one of the most popular sports. Knowing the basic types and how to defend yourself against them is critical for a network administrator (or an individual) who wants to traverse the internet safely. Stopping a live DDoS attack can be difficult, and it may have an impact on your legitimate users. This is why it’s critical to take proactive measures.

Juniper Networks and Corero Network Security team up to give Critical DDoS Protection Solution to Plusnet GmbH

Corero Network Security plc, a global provider of real-time, automated Distributed Denial of Service (DDoS) cyber defence solutions and Juniper Networks, a worldwide leader in secure, AI-driven networks, have collaborated to provide Plusnet, a provider of communications and network services to 25,000 enterprises in Germany, with a combined DDoS Protection Solution to safeguard its infrastructure, business, and clients.

DDoS attacks have been a part of the threat landscape for more than two decades, but their frequency, scale, and intelligence are constantly increasing. Plusnet, which serves 200 cities and regions across Germany, used to examine anomalies in traffic patterns using an internal data filtering system. However, when attacks grew and changed, this in-house security solution required manual intervention, which was neither practicable nor successful. To protect its national network from attack-driven outages, Plusnet wanted to automate DDoS mitigation with effective, dynamic, and scalable security.

Ralf Weber, Head of Competence Center Network & Security, Plusnet said, “During the testing phase of the Juniper-Corero solution, we could immediately see a manageable stream of DDoS attacks. With the Juniper-Corero solution, Plusnet is able to further improve network protection without any significant impact on network performance.”

“More than ever before, providers need to ensure that their infrastructure and business operations are always available to deliver an exceptional user experience. This can only be achieved when security is built into the same network infrastructure that provides connectivity and extended across every point of connection. Plusnet is a great example that leverages Juniper Connected Security to enable the threat-aware network, ensuring its operations are comprehensively protected 24/7 against the growing risk of DDoS attacks,” said Samantha Madrid, Vice President, Security Business & Strategy, Juniper Networks.

“We are very pleased to continue partnering with Juniper Networks to provide a superior DDoS solution that is now protecting thousands of customers around the globe. The SmartWall TDD solution couples Corero’s surgically accurate, real-time automatic DDoS protection with the high-performance packet filtering of Juniper MX Series routers. This, along with the comprehensive visibility into attacks, enabled Plusnet to implement a cutting-edge solution that can detect and mitigate DDoS attacks in seconds to protect its network and the ones of its customers,” said Lionel Chmilewsky, Chief Executive Officer at Corero Network Security.

Corero’s latest software release improves DDoS protection at the network edge and for 5G

Corero Network Security plc (AIM: CNS.L), a leading provider of real-time, high-performance, automated Distributed Denial of Service (DDoS) cyber defense solutions, has released the latest version of its award-winning SmartWall Threat Defense Director product. These new features make it easier than ever for Corero and Juniper clients to keep their businesses running by providing a cutting-edge, an automatic DDoS Protection solution and deploy it as a value-added service to their downstream customers.

Traditional blackholing, out-of-band scrubbing centres, on-demand cloud services, and human intervention are no longer viable business practises as DDoS attacks continue to expand in scale, frequency, and sophistication. Juniper Networks and Corero Network Security are continuing their long-standing and successful partnership to create a groundbreaking new solution against DDoS attacks using Juniper NetworksTM MX Series Universal Routing Platforms and Corero Network Security’s SmartWall software intelligence. This integrated DDoS solution provides automatic, real-time detection and line-rate mitigation, scaling from 100 Gbps to 40 Tbps as a customer’s needs develop. Across the network edge, it uses always-on packet-level monitoring, automated machine analysis, and high-performance infrastructure-based enforcement.

Today, we are highlighting some of the enhancements made to our SmartWall Threat Defense Director (TDD):

  • Visibility into 5G mobile traffic for subscriber-side DDoS protection with GTP payload inspection;
  • Attack source Geolocation and Autonomous System awareness IP intelligence Plug-in;
  • DDoS protection as a service with multi-tenant Service Portal and Tenant-Awareness Plug-in;
  • Flexible upstream Traffic Control with BGP policy for saturation prevention and multi-vendor support.

“The newest enhancements to SmartWall TDD now make it easier than ever for customers to deliver automatic, real-time DDoS protection. Our partnership with Juniper allows both Corero and Juniper to deploy an industry leading DDoS protection solution, leveraging their SDN-enabled MX Series routers and Corero’s software intelligence. These software enhancements enable us to deliver leading protection against the growing threat of DDoS.” said Corero CTO, Ashley Stephenson.
