High-defence servers are the core infrastructure in the field of network security, and their core value lies in the fact that through theHardware Enhancement, Intelligent Defence and Resilient Architectureof deep integration to provide 24/7 attack resistance for critical services.
I. High-defence server technology architecture
1. Hardware layer: the cornerstone of physical defence
- Customised hardwareThe Node is powered by Xeon scalable processors such as Intel Xeon Platinum 8380 with high-capacity DDR4 RAM (starting at 1TB), and PCIe 4.0 SSDs, allowing a single node to handle 10 million concurrent requests per second.
- distributed clusterBGP multi-line access (e.g., Telecom/Unicom/Mobile/Education) for global node load balancing, with a single cluster capable of withstanding 5Tbps-level DDoS attacks.1.
- hardware firewall: Deploy professional anti-DDoS appliances (such as Radware DefensePro) that support millions of packets per second filtering and can identify and block 4000+ attack types such as SYN Flood, UDP Flood, and more.
2. System layer: the brain of intelligent defence
- Flow Cleaning Technology::
- black hole routing: Directs attack traffic to the null0 interface with less than 10ms processing latency and 1/10th of the resource consumption of traditional ACLs4.
- AI Drive Detection: Analyses traffic features based on deep learning models (e.g. LSTM), identifying new attacks with 99.7% accuracy.16.
- Behavioural fingerprinting library: Create 10 million IP behavioural profiles and block anomalous requests (e.g., high-frequency access in CC attacks) in real time.
- Resilient Extension MechanismDynamic resource allocation through Elastic Scaling AS, scaling up to 1000 server clusters in 5 minutes.1.
3. The application layer: the end of protection in depth
- Protocol level defence::
- TCP proxy: Hides the source IP and forwards traffic through a Layer 4 proxy to defend against SYN Flood attacks.
- HTTP Authentication: Filtering malicious requests based on cookie challenges, human identification (e.g. Google reCAPTCHA).
- data security::
- encrypted transmissionSupport TLS 1.3 and State Secrets SM2/SM3 algorithms to ensure data security in transmission and storage.
- Zero Trust Architecture: Prevent internal penetration through continuous authentication (e.g. biometrics + dynamic tokens).
II. Practical capabilities: closing the whole link from defence to response
1. Attack identification: millisecond threat awareness
- multidimensional detection::
- Flow analysis: Real-time monitoring of traffic peaks, protocol distribution, and identification of unusual fluctuations (e.g., sudden 100-fold increase in traffic).
- Log Audit: Correlate and analyse web logs and system logs to locate the source of the attack (e.g. scanner fingerprints, malicious payloads).
- threat intelligence: Interfacing with global threat intelligence platforms (e.g., IBM X-Force) for real-time attack signature libraries.
2. Attack response: automated disposal system
- Dynamic Strategy Adjustment::
- Intelligent BlockingGradient blocking of attacking IPs (e.g. 1 hour / 1 day / permanent), with support for automatic unblocking.
- flow scheduling: Divert attack traffic to the cleaning centre, normal traffic goes straight to the source station to ensure that the business is not perceived13.
- emergency response::
- pre-trigger: 50+ pre-programmed attack scenarios with automatic activation of backup clusters.
- human intervention: 24/7 team of security experts with in-depth traceability and policy optimisation in 10 minutes.
3. Validation of effectiveness: quantification of defence indicators
- protection capabilitySingle node can defend against 2Tbps traffic attacks with 99.995% cleaning success rate.19.
- responsiveness: Attack recognition time < 500ms, policy validation time < 2s.
- Operational impact: Normal traffic latency increase < 5ms, throughput loss < 1%.
III. Industry practice: customised solutions for different scenarios
1. Game industry: guaranteeing real-time interaction
- Scenario pain points: DDoS attacks cause game servers to go down and player churn as high as 30%.
- Solutions::
- High Defence CDN: Cache game resources from 200+ nodes worldwide, speeding up access while hiding the source site.6.
- UDP protocol optimisation: Deeply optimised for commonly used protocols in games (e.g. KCP) to ensure real-time matchmaking stability.
- case (law)An MMORPG game successfully resisted 500 DDoS attacks in a single day after accessing a high defence server, and the length of time players were online increased by 25%.
2. The financial sector: compliance and security at the same time
- compliance requirement: Conforms to standards such as Equalisation 2.0, PCI DSS, etc., with a data retention period of 6 months or more.
- Technical programme::
- hardware isolation: Core trading systems are deployed on separate physical servers, isolated from the Internet.
- Zero Trust Network: Protection against man-in-the-middle attacks through dynamic authentication (e.g. voice recognition)17.
- case (law)A bank's Internet banking system deployed Deepsign's next-generation firewall and successfully blocked 220,000 malicious outreach attempts, achieving zero security notifications.17.
3. The e-commerce industry: traffic peaks during big promotions
- Scenario Challenge: A 10-fold surge in traffic during Double 11 requires defending against CC attacks and woolgathering.
- Solutions::
- Intelligent current limiting: Predicts peaks based on historical data and dynamically adjusts QPS thresholds.
- Behavioural analysis: Identify abnormal ordering behaviour (e.g. same IP high-frequency robbing) and automatically trigger human-machine verification.
- case (law)An e-commerce platform used AliCloud high defence IPs to handle 5 million QPS attacks during the Double 11 period in 2023, maintaining a transaction success rate of 99.9%.19.
IV. Cost and selection: balancing cost-effectiveness and long-term value
1. Cost components

VII. Frequently Asked Questions
Q: What is the difference between a high defence server and a normal server?
A: High-defence servers achieve attack resistance through hardware reinforcement (e.g., dedicated anti-DDoS devices), intelligent traffic cleansing (AI recognition of attack characteristics), and resilient architecture (dynamically expanding resources), while ordinary servers only provide basic network protection. For example, high defence servers can protect against 10Tbps level attacks, while ordinary servers usually only support 100G level protection.

For example, high defence servers can protect against 10Tbps level attacks, while ordinary servers usually only support 100G level protection.
Q: Can high defence servers defend against all network attacks?
A: No. High-defence servers mainly target traffic-based attacks such as DDoS and CC attacks, but for application-layer vulnerabilities (such as SQL injection) they need to be combined with a WAF (Web Application Firewall) or code auditing. For example, AWS Shield Advanced needs to be coupled with AWS WAF for full-stack protection.

Q: What is the difference between BGP and normal high defence?
A: BGP high defence achieves intelligent traffic scheduling and fast cleansing with lower latency and higher stability through multi-operator line redundancy. For example, Cloudflare's Anycast technology disperses attack traffic to global nodes for cleaning, while ordinary high defence relies on single-node protection.

Q: How to verify the actual protection ability of high defence servers?
A: Available through the service providerProtection Report(e.g., attack interception volume, cleaning success rate),SLA commitments(e.g. 99.99% availability) andThird party testing(e.g., CVE vulnerability scanning, penetration testing) assessments. For example, Akamai regularly publishes data on the number of DDoS attacks it protects against.

Q: How do companies choose the right high defence service provider?
A: Needs to be considered:
A: Needs to be considered:
-
- protection capability(e.g. 500G+ recommended for the gaming industry);
- Global Node Coverage(Cross-border operations require multi-regional deployment);
- responsiveness(e.g. 08Host promises attack identification < 500ms);
- Compliance Certification(e.g., PCI DSS, ISO 27001).
Q: Which is more cost-effective, building my own high defence or using a cloud service?
A: In the short term, cloud services are more economical (e.g., AWS monthly fee of 1-5 million yuan), and in the long term, self-built costs may be lower (reusable hardware). However, cloud services have the advantages of elastic expansion and zero operation and maintenance, which is suitable for scenes with large business fluctuations (such as e-commerce promotion).
