FortiWeb is a web application firewall (WAF) developed by Fortinet, designed to protect web applications and APIs from a wide range of cyber threats, including web-based attacks, such as SQL injection, cross-site scripting (XSS), and application-layer DDoS attacks. FortiWeb helps organizations safeguard their web applications, prevent data breaches, and maintain compliance with regulatory requirements.

Here are key aspects of FortiWeb:

Web Application Security: FortiWeb provides comprehensive protection for web applications and APIs against common web-based attacks, including OWASP Top 10 vulnerabilities and emerging threats. It inspects incoming HTTP/HTTPS traffic, analyzes request patterns and payloads, and applies security policies to block malicious requests and mitigate security risks before they can reach the application server.

Layer 7 Defense: FortiWeb operates at Layer 7 (application layer) of the OSI model, allowing it to inspect and filter web traffic based on application-level attributes, such as HTTP headers, parameters, cookies, and content. It identifies and blocks malicious requests, malformed HTTP requests, and protocol violations, while allowing legitimate traffic to pass through to the web application server.

Signature-based and Behavioral Detection: FortiWeb uses a combination of signature-based detection and behavioral analysis techniques to identify and block known and unknown web-based threats. It maintains a database of attack signatures, patterns, and heuristics to detect known attack patterns, while also analyzing request behaviors, session anomalies, and user interactions to identify suspicious activities indicative of zero-day attacks and advanced threats.

Positive and Negative Security Models: FortiWeb supports both positive security models (allow-listing) and negative security models (deny-listing) for web application protection. It allows administrators to define security policies based on whitelisting or blacklisting specific URL patterns, parameters, HTTP methods, and user agents, enabling fine-grained control over allowed and blocked web traffic.

SSL/TLS Offloading and Inspection: FortiWeb can offload SSL/TLS decryption and inspection tasks from web servers, allowing it to inspect encrypted web traffic for threats and vulnerabilities. It decrypts incoming HTTPS traffic, performs security checks and content inspection, and re-encrypts the traffic before forwarding it to the backend web application server, ensuring end-to-end security without compromising performance.

Web Application Firewall Rules: FortiWeb offers a wide range of predefined and customizable firewall rules, policies, and security controls to protect web applications against specific attack vectors and security threats. It includes rules for blocking SQL injection, XSS, CSRF (Cross-Site Request Forgery), file inclusion, directory traversal, and other common web vulnerabilities, as well as the ability to create custom rules tailored to the organization's unique security requirements.

Integration with Fortinet Security Fabric: FortiWeb seamlessly integrates with Fortinet's Security Fabric, allowing it to share threat intelligence, security policies, and configuration data with other Fortinet security devices and services. This integration enables coordinated threat response, automated enforcement of security policies, and unified visibility and control across the entire security infrastructure, including network firewalls, intrusion prevention systems, and endpoint security solutions.

Overall, FortiWeb provides organizations with robust web application security capabilities to protect against web-based threats, secure sensitive data, and maintain compliance with regulatory requirements. It helps organizations safeguard their web applications and APIs against evolving cyber threats, ensuring continuous availability, integrity, and confidentiality of their online assets.
