DDoS Protection with WAF — Complete Web Security

DDoS protection and web application firewalls address different threat categories, but they work best when deployed together. DDoS mitigation handles volumetric and protocol attacks that aim to overwhelm your infrastructure. A WAF handles application-level exploits that aim to compromise your data, inject malicious code, or abuse your application logic.

Without DDoS protection, a WAF can be overwhelmed by the sheer volume of requests during a flood attack. Without a WAF, DDoS protection alone will not stop an attacker who sends a carefully crafted SQL injection payload at a normal request rate. Together, they create a comprehensive security posture that addresses both availability threats and application security threats.

AnubizHost integrates both capabilities into our hosting infrastructure. The DDoS mitigation layer handles volumetric and network-layer attacks at the edge, while WAF functionality provides application-layer inspection for common web exploits. The result is a single hosting solution that protects against the full spectrum of threats facing web applications.

Our WAF capability protects against the OWASP Top 10 web application vulnerabilities and beyond. SQL injection attacks that attempt to manipulate database queries are detected and blocked based on payload analysis. Cross-site scripting (XSS) attempts that inject malicious JavaScript into web pages are neutralized before they reach your application.

Path traversal attacks, command injection, file inclusion vulnerabilities, and XML external entity (XXE) attacks are all handled by our WAF rules. The system maintains an extensive rule set that is regularly updated to cover newly discovered attack techniques and vulnerability disclosures.

The WAF operates on HTTP request content, inspecting URLs, headers, query parameters, cookies, and request bodies for malicious patterns. Matching requests are blocked or logged depending on your configuration, and legitimate requests pass through with negligible added latency. For applications that handle sensitive data — user credentials, payment information, personal records — the WAF provides an essential additional layer of defense.

Every web application is different, and a one-size-fits-all WAF configuration will generate false positives or miss application-specific threats. AnubizHost WAF rules are customizable, allowing you to tune the protection for your specific application's needs.

If your application legitimately uses patterns that trigger WAF rules — for example, a code editor that accepts SQL syntax in form fields — you can create exceptions that whitelist those specific use cases while maintaining protection everywhere else. Conversely, if your application has endpoints that are particularly sensitive, you can apply stricter rules to those paths.

For customers using our managed protection service, our team handles the WAF configuration based on your application profile. We analyze your application's normal traffic patterns, identify the most relevant threat categories, and configure rules that provide maximum protection with minimum false positives. The configuration is continuously refined based on the traffic and threats we observe.

DDoS protection is included with every AnubizHost server by default. WAF functionality can be enabled through your account dashboard or configured by our team for managed protection customers. The two layers work in sequence — DDoS mitigation first removes volumetric and protocol attacks, then the WAF inspects the remaining clean traffic for application-layer exploits.

This layered architecture is efficient because the DDoS mitigation dramatically reduces the traffic volume that the WAF must inspect. A 50Gbps attack might be reduced to a trickle of legitimate traffic after DDoS filtering, allowing the WAF to apply deep inspection without performance concerns.

To get started, deploy your server, set up your web application, and enable WAF protection. Review the default rule set and customize it for your application if needed. Monitor the WAF dashboard for blocked threats and adjust rules as necessary. Combined with our always-on DDoS mitigation, your web application is protected against both brute-force attacks and sophisticated exploits from the moment it goes live.
