Today’s DDoS attacks are becoming increasingly complex and large-scale, posing a serious threat to the network infrastructure of ISPs and data centers. Downtime due to DDoS leads to financial losses, reputational risks, and reduced customer service quality. In this situation, rapid DDoS mitigation and DDoS protection automation are critical. The Arbor BGP Flowspec solution, offered by NWU, significantly reduces the response time to an attack (MTTR) and minimizes the negative consequences for your business.
The Evolution of DDoS Protection: From RTBH to BGP Flowspec
Traditional DDoS protection methods, such as RTBH, have several limitations. RTBH involves completely blocking traffic directed to the attacked IP address, which leads to undesirable consequences for legitimate users. A more modern and effective approach is to use BGP Flowspec DDoS. Let’s understand the difference between RTBH vs Flowspec.
Advantages of BGP Flowspec over RTBH
- Granularity: Flowspec allows you to filter traffic based on various parameters, such as IP address, port, protocol, and TCP flags, while RTBH blocks all traffic to the IP address.
- Accuracy: Flowspec minimizes the impact on legitimate users by blocking only malicious traffic.
- Automation: Flowspec allows you to automate the process of distributing filtering rules across the network using the BGP protocol.
How BGP Flowspec and Arbor Networks Work
BGP Flowspec is an extension of the BGP protocol that allows you to distribute traffic filtering rules across the network. When a DDoS attack detection system, such as Arbor TMS (Threat Management System), detects anomalous traffic, it generates Flowspec rules, which are then distributed across the network using BGP. Routers that support BGP Flowspec apply these rules to filter traffic, blocking malicious packets and redirecting legitimate traffic.
Components of the Arbor BGP Flowspec Solution
- Arbor SP/TMS (Sightline): A DDoS attack detection and analysis system that identifies anomalous traffic and generates Flowspec rules.
- Routers with BGP Flowspec Support: Routers that apply Flowspec rules to filter traffic.
Benefits of Using Arbor BGP Flowspec for DDoS Protection
The Arbor BGP Flowspec solution provides a number of key benefits for protecting against DDoS attacks:
Speed and Automation
One of the main advantages is DDoS protection automation. Arbor TMS automatically detects attacks and generates Flowspec rules, which are distributed across the network without human intervention. This significantly reduces the response time to an attack and minimizes downtime. The solution provides rapid DDoS mitigation, which is critical for maintaining business continuity.
Scalability and Flexibility
The Arbor Flowspec solution scales to meet your network needs. It can be deployed in both large ISP networks and small data centers. The flexibility of the solution allows you to adapt it to various use cases and security requirements.
Improved Visibility and Control
The Arbor Networks solution provides improved visibility and control over network traffic. You can monitor DDoS attacks in real time, analyze their characteristics, and take steps to prevent them.
BGP Flowspec Implementation: Features and Recommendations
Configuring BGP Flowspec for ISPs
Configuring BGP Flowspec requires specific knowledge and experience. It is necessary to properly configure routers that support BGP Flowspec and integrate them with the DDoS attack detection system. NWU offers professional services for implementing and configuring Arbor Networks to ensure maximum protection effectiveness.
Zero-touch DDoS mitigation
The concept of zero-touch DDoS mitigation assumes that the protection system operates completely automatically, without human intervention. Arbor BGP Flowspec allows you to get closer to this goal by automating the detection, analysis, and mitigation of DDoS attacks.
Use Case: Protecting a Large ISP with Arbor BGP Flowspec
Imagine a large ISP that is subjected to DDoS attacks of varying complexity every day. Traditional methods of protection cannot cope with the growing volume and variety of attacks, which leads to network overload and a deterioration in the quality of customer service. Implementing BGP Flowspec and Arbor Networks allows ISPs to automate the process of protecting against DDoS attacks, significantly reduce the response time to an attack, and minimize the negative consequences for the business. Thanks to granular traffic filtering, Flowspec allows you to block only malicious traffic without affecting legitimate users.
Conclusion
BGP Flowspec DDoS in combination with Arbor Networks solutions is a powerful tool for protecting against modern DDoS threats. DDoS protection automation, rapid DDoS mitigation and MTTR significantly reduce downtime and minimize financial losses. If you are looking for a reliable and effective solution to protect your network from DDoS attacks, pay attention to Arbor BGP Flowspec from NWU. This is an investment in the stability and security of your business.

Frequently Asked Questions on: Rapid DDoS Mitigation with BGP Flowspec and Arbor
-
What is BGP Flowspec and how does it help in combating DDoS attacks?
BGP Flowspec is an extension of the BGP protocol that allows for the distribution of traffic filtering rules across the network. This allows for targeted blocking of malicious traffic directed at attacked resources, minimizing the impact on legitimate users. -
What are the main advantages of BGP Flowspec over the traditional RTBH method?
BGP Flowspec provides granularity, accuracy, and automation, unlike RTBH, which blocks all traffic to the attacked IP address. Flowspec allows you to filter traffic by various parameters (IP, port, protocol), blocking only malicious traffic and automating the process of distributing filtering rules. -
What components are included in the Arbor BGP Flowspec solution?
The Arbor BGP Flowspec solution includes Arbor TMS (a system for detecting and analyzing DDoS attacks), Arbor AED (a device for distributing Flowspec rules), and routers that support BGP Flowspec. -
How does Arbor TMS detect and respond to DDoS attacks?
Arbor TMS analyzes network traffic to identify anomalies characteristic of DDoS attacks. When attacking traffic is detected, TMS generates Flowspec rules, which are then distributed across the network to block malicious packets. -
What is Arbor AED and what role does it play in the solution?
Arbor AED (Edge Defense) is a device that receives Flowspec rules from Arbor TMS and distributes them across the network using the BGP protocol. It acts as an intermediary between the attack detection system and the routers that apply the filtering rules. -
What does the concept of "zero-touch DDoS mitigation" mean and how does Arbor BGP Flowspec implement it?
"Zero-touch DDoS mitigation" means fully automated protection against DDoS attacks without human intervention. Arbor BGP Flowspec approaches this goal by automating the detection, analysis, and mitigation of DDoS attacks, allowing the system to respond to threats in real time. -
How scalable is the Arbor Flowspec solution for DDoS protection?
The Arbor Flowspec solution scales to meet network needs and can be deployed in large ISP networks as well as small data centers, adapting to various use cases and security requirements. -
What knowledge and experience are required to configure BGP Flowspec?
Configuring BGP Flowspec requires specific knowledge and experience in network technologies and the BGP protocol. It is necessary to correctly configure routers that support BGP Flowspec and integrate them with the DDoS attack detection system. -
What visibility and control over traffic does the Arbor Networks solution provide?
The Arbor Networks solution provides improved visibility of network traffic and control over it. You can track DDoS attacks in real time, analyze their characteristics, and take measures to prevent them. -
