As regional military conflicts escalate, cyberspace has become a critical battleground, with core WEB application systems frequently targeted by adversaries. Attackers tamper with application content and inject anti-social or anti-government rhetoric, disrupting cyberspace order and inciting public panic, severely damaging institutional credibility. WEB services serve as key platforms for information dissemination and core operations across industries. If tampered with, infiltrated, or disrupted, they face dire consequences—including misinformation, data breaches, and service interruptions—posing threats to national security and social stability. Thus, WEB security protection is now an urgent priority.

As WEB security threats become more complex, NSFOCUS, leveraging over two decades of cybersecurity expertise, has developed a comprehensive WEB security protection system centered on its Web Application Firewall (WAF) and Host-based Web Tamper-Proofing System (HDS). This system addresses core challenges in WEB security, providing end-to-end protection from attack interception to content safeguarding.

WAF: Multi-Dimensional Protection

When faced with threats like crawler attacks, WEB vulnerability exploits, and API abuse, NSFOCUS WAF delivers multi-dimensional protection to secure business operations:

1. Precise Blocking of Automated Attacks:

Malicious crawlers scrape core data, brute-force attacks target account credentials, and automated scanners probe for vulnerabilities, placing WEB services and data at constant risk. NSFOCUS employs a systematic BOT traffic mitigation solution, using JS script deployment for browser environment identification, dynamic Web page link obfuscation, encrypted data submission, and sensitive information filtering. This enables precise detection and blocking of automated attacks, preventing data theft, vulnerability scanning, and brute-force attacks while ensuring WEB and business data security.

2. API Security Protection:

Unclear API asset inventories, lingering zombie interfaces, and unregulated API calls expand the attack surface, making them prime targets for hackers. WAF automatically identifies business API assets, cleans up zombie APIs, and enforces OAS-compliant API calls, effectively defending against known and unknown threats while reducing business disruptions and exposure risks.

3. Effective Defense Against Known and Zero-Day Vulnerabilities:

Numerous WEB application vulnerabilities and thier long patching cycles leave zero-day exploits often lack effective defenses. Traditional protections suffer from high false positives/negatives, rendering security measures ineffective. NSFOCUS, with 17 years of WEB attack and defense rule accumulation, combines semantic analysis, intelligent analysis, and threat intelligence. Through a robust rule system, high-performance semantic engine, and strict protocol validation, it precisely identifies and blocks known and zero-day attacks with minimal false positives/negatives, ensuring comprehensive WEB attack defense.

4. High Reliability Mechanisms for Business Continuity:

Security devices can disrupt business operations, and complex maintenance configurations make it difficult to balance security and availability, impacting stability and compliance. WAF features multi-dimensional fault detection and self-healing mechanisms, along with layered operational modes, ensuring security while enhancing business reliability, reducing maintenance pressure, and meeting national cybersecurity compliance requirements.

Web Tamper-Proofing System: Kernel-Level Protection for Content Security

To proactively prevent malicious tampering with web applications—particularly in high-risk scenarios exposed to external threats—NSFOCUS Host-based Web Tamper-Proofing System (HDS) utilizes third-generation kernel driver technology to build an “unbreakable” shield for web content:

1. Real-Time Interception + Automatic Recovery:

Manual detection of web tampering is slow, and delayed or incomplete recovery can lead to severe reputational damage and regulatory penalties. HDS uses server file access driver technology to monitor static web pages, dynamic scripts, and folder attribute changes in real time. Upon detecting unauthorized tampering, it immediately blocks the attack; if files are compromised, the system automatically restores them from a trusted source, eliminating risks of malicious content tampering and preserving institutional integrity and information authenticity.

2. Multi-Scenario Deployment for Complex Business Needs:

Traditional business sites are dispersed, with complex architectures and hybrid local/cloud environments, making unified protection difficult without disrupting operations. HDS supports local, cloud, and cross-heterogeneous network deployments, with centralized platform management and encrypted communication between monitoring/backup and management endpoints. It adapts to both traditional local websites and cloud-native business scenarios, simplifying deployment without altering existing network structures. This enables rapid, large-scale website cluster management, widely applicable to government, finance, energy, and telecommunications sectors.
