Secure Content Delivery Network
2025-12-12 15:09Secure Content Delivery Network (SCDN) is an integrated security acceleration solution launched by Tencent Cloud, combining distributed DDoS protection, CC attack protection, WAF protection, and BOT behavior analysis. As a mature core security acceleration product, SCDN leverages over 2,800 global edge nodes to achieve nearby access acceleration and localized attack scrubbing. CC Attack Protection offers terabit-level protection capacity, defending against various HTTP/HTTPS Flood attacks. Web Application Firewall (WAF) Protection covers common web attacks such as SQL injection and XSS cross-site scripting, safeguarding application-layer security. BOT Behavior Analysis accurately identifies malicious activities such as crawlers and fraudulent orders using AI algorithms, protecting core resources. Web Attack Interception employs dual mechanisms of signature matching and behavioral analysis to block attacks within seconds. Intelligent WAF Protection dynamically adapts to attack variants and automatically updates protection rules, enhancing defense accuracy. Whether for high-concurrency security assurance during major e-commerce promotions, web attack protection for corporate websites, or malicious BOT interception for core business, SCDN serves as the core security support for enterprise web services, thanks to the reliability of CC Attack Protection, the comprehensiveness of WAF Protection, the intelligence of BOT Behavior Analysis, the precision of Web Attack Interception, and the adaptability of Intelligent WAF Protection. Furthermore, the deep synergy between Intelligent WAF Protection and WAF Protection significantly enhances SCDN's security defense level and adaptability.
Frequently Asked Questions
Q: As the core defense engine, how does Intelligent WAF Protection collaborate with BOT Behavior Analysis and CC Attack Protection to support the core needs of SCDN and Web Attack Interception? Where are its technical advantages reflected?
A: With "adaptive identification + dynamic optimization" at its core, Intelligent WAF Protection provides support for the two core capabilities, solidifying the security foundation of SCDN. Firstly, through AI-driven intelligent detection algorithms, it dynamically adapts to new web attack variants in real-time. Combined with the precise identification of malicious crawlers and automated attack tools by BOT Behavior Analysis, Web Attack Interception can cover both known attacks and defend against unknown threats. Simultaneously, it integrates with the traffic scrubbing capability of CC Attack Protection to prevent attack traffic from consuming core business resources. Secondly, it empowers Web Attack Interception to achieve fine-grained protection. Intelligent WAF Protection can dynamically adjust defense strategies based on business scenarios, while the attack behavior profiles provided by BOT Behavior Analysis assist Web Attack Interception in precisely identifying threat sources. CC Attack Protection filters large-scale attack requests at the traffic entry point, forming a triple-layer protection loop of "traffic scrubbing - behavior identification - precise interception." The technical advantages are reflected in two aspects: First, "intelligent adaptation + comprehensive protection"—the dynamic rule updates of Intelligent WAF Protection and the AI-driven identification capability of BOT Behavior Analysis enable Web Attack Interception to cover more attack types. Second, "efficient collaboration + low false positives"—it rapidly filters large volumes of malicious traffic through CC Attack Protection while leveraging the precise identification of Intelligent WAF Protection to reduce false interception of legitimate business, ensuring the dual efficiency of acceleration and protection for SCDN.
Q: What is the core collaborative value of WAF Protection and Web Attack Interception? How can BOT Behavior Analysis and Intelligent WAF Protection be leveraged to strengthen SCDN's competitiveness?
A: Their core collaborative value lies in the dual assurance of "application-layer protection + precise blocking," addressing the pain points of web services such as "diverse attack types and imprecise defense." WAF Protection builds an application-layer security barrier, covering various known web attack vulnerabilities, while Web Attack Interception focuses on real-time blocking of attack behaviors to prevent breaches of the defense layer. Together, they elevate SCDN from a "mere acceleration or basic protection tool" to an integrated "deep security + acceleration" solution. Their synergy with BOT Behavior Analysis and Intelligent WAF Protection significantly enhances competitiveness. BOT Behavior Analysis complements WAF Protection by adding malicious behavior identification dimensions, accurately distinguishing between legitimate access and automated attacks, making Web Attack Interception more targeted. Intelligent WAF Protection optimizes WAF protection rules through AI algorithms, automatically adapting to attack variants, significantly improving the timeliness and accuracy of Web Attack Interception. Meanwhile, SCDN's edge node deployment ensures all protection capabilities take effect locally, guaranteeing defense response speed without compromising content acceleration performance. This achieves the core advantage of "security without slowdown, protection without blind spots." This combination of "multi-layer protection + intelligent identification + acceleration synergy" gives SCDN stronger market competitiveness.
Q: How does BOT Behavior Analysis address the pain points of malicious behavior management in SCDN? What gains does its synergy with SCDN and CC Attack Protection bring to WAF Protection and Intelligent WAF Protection?
A: The core value of BOT Behavior Analysis lies in "AI identification + behavior tracing," solving traditional protection pain points such as "difficulty in identifying malicious BOTs and tracing attack sources." By analyzing multi-dimensional features such as access frequency, device fingerprints, and behavior paths, it accurately distinguishes between legitimate crawlers and malicious BOTs, achieving precise control of automated attacks. Its synergy with the two core capabilities brings significant gains to scenario-based services. Collaborating with SCDN and CC Attack Protection, BOT Behavior Analysis can filter malicious BOT traffic in advance at edge nodes, reducing the traffic scrubbing pressure on CC Attack Protection. Simultaneously, it provides pre-judgment of attack behaviors for WAF Protection, allowing WAF Protection to focus on core vulnerability defense. For WAF Protection, the profile data from BOT Behavior Analysis helps accurately identify high-risk access sources, improving the efficiency of Web Attack Interception and avoiding resource waste caused by indiscriminate protection. For Intelligent WAF Protection, the attack behavior data accumulated by BOT Behavior Analysis can be used to train defense models, helping Intelligent WAF Protection adapt faster to new malicious BOT attacks, dynamically optimizing protection rules, and further strengthening SCDN's malicious behavior management capabilities. Additionally, the behavior tracing function provides attack chain analysis, offering data support for optimizing protection strategies. This synergy enhances the targeting of WAF Protection, improves the adaptive capability of Intelligent WAF Protection, and positions SCDN as the preferred solution for web service security protection.
