Assumptions for Smooth Enablement of Network Protection Solution

To ensure seamless enablement of the Network Protection solution, the following key assumptions are taken into consideration:

1. Focus on CSP Backbone
   The policy of Nexusguard Network Protection is specifically designed to prioritize the availability and resilience of the CSP’s local backbone network.
   ‍
2. Bastions Server Deployment
   Achieving successful implementation of Network Protection relies on deploying an on-premise Bastions server that plays a crucial role in bolstering the CSP's network against malicious attacks. However, it is important to recognize that the smooth delivery of the CSP's services is contingent upon the availability of sufficient Internet bandwidth within its backbone infrastructure. This ensures that the Bastions server can effectively perform its designated functions in the event of an attack, while also enabling the successful delivery of the Clean Pipe service.
   ‍
3. Multi-layered Defense Approach
   Clean Pipe serves as a highly efficient and precise solution, offering targeted protection to downstream clients of CSPs. With its customizable features, Clean Pipe effectively mitigates a wide array of threats, thereby safeguarding the integrity and availability of client networks. By tailoring protection measures to meet the unique requirements of each client, Clean Pipe provides an optimized and personalized defense mechanism, ensuring robust security.
   
   Network Protection, on the other hand, places a primary focus on fortifying the CSP's own infrastructure. Network Protection encompasses a comprehensive suite of protective measures, including robust network monitoring, proactive threat detection, and advanced mitigation techniques. These measures collectively reinforce the resilience of the CSP's infrastructure, enabling both the seamless execution of daily operations and uninterrupted delivery of the Clean Pipe service.
   
   Together, Clean Pipe and Network Protection establish a multi-layered defense strategy, forming an impregnable barrier against a wide range of threats. While Clean Pipe caters to the specific protection needs of downstream clients, Network Protection guarantees the reliable and continuous delivery of the CSP’s daily operations as well as the successful delivery of the Clean Pipe service. This strategic approach is driven not only by commercial considerations but also by the need to address management complexities, scalability requirements, and operational challenges associated with protecting a diverse ecosystem.

4. Comprehensive IP Prefix Registration 
   To establish robust and all-encompassing protection, it is imperative to register all IP prefixes that may traverse the CSP's backbone. This crucial step allows Nexusguard Network Protection to actively monitor and efficiently mitigate potential threats throughout the entire network ecosystem.

‍

CSP Network Protection Scope 

Nexusguard Network Protection offers a comprehensive solution to safeguard a CSP's own local network infrastructure and all registered IPv4 & IPv6 network address space from volumetric DDoS attacks, including but not limited to TCP, UDP and ICMP floods. 

The solution extends its protection to cover all registered network address spaces of clients, utilizing IP prefix length /24 currently registered with Nexusguard as well as the entirety of registered network address space belonging to downstream entities, utilizing IP prefix length /24, encompassing the IP prefixes currently registered under multi-homed clients with a distinct Autonomous System Number (ASN).

To streamline operations, Nexusguard Network Protection employs a systematic approach rather than creating custom-built comprehensive policies for each individual target or network connected to the CSP, leveraging flow data collection and analysis through on-premise Bastions servers to detect DDoS attacks.

In the event of an attack, Nexusguard Network Protection employs iBGP routing to divert the under attack IP prefix, effectively minimizing the impact. Clean traffic is then safely returned to the CSP's network via the on-premise Bastions server, guaranteeing uninterrupted service availability and network performance.
