Radware Web Application Firewall: Comprehensive Protection Against Modern Threats

In today’s digital landscape, web applications are prime targets for cyberattacks. Organizations face an ever-increasing array of threats, from common vulnerabilities like SQL injection and cross-site scripting (XSS) to sophisticated application-layer DDoS attacks and bot-driven fraud. A robust web application firewall (WAF) is essential for protecting these critical assets. Radware’s web application firewall offers a comprehensive solution designed to safeguard web applications from a wide range of threats, ensuring business continuity and data security.

Understanding Web Application Firewalls

A web application firewall acts as a security barrier between web applications and the internet. It analyzes incoming HTTP/HTTPS traffic, identifying and blocking malicious requests before they reach the application server. Unlike traditional firewalls that operate at the network layer, WAFs operate at the application layer (Layer 7), providing granular control over web traffic and enabling advanced security policies.

The primary goal of a web application firewall is to protect web applications from attacks that exploit vulnerabilities in the application code. These vulnerabilities can arise from various factors, including coding errors, outdated software, and misconfigurations. By inspecting HTTP requests and responses, a WAF can detect and prevent attacks such as:

SQL Injection: Exploits vulnerabilities in database queries to gain unauthorized access to sensitive data.
Cross-Site Scripting (XSS): Injects malicious scripts into web pages, allowing attackers to steal user credentials or deface websites.
Cross-Site Request Forgery (CSRF): Tricks users into performing actions they didn’t intend to, such as changing passwords or making unauthorized purchases.
Application-Layer DDoS Attacks: Overwhelms web applications with malicious traffic, causing them to become unavailable to legitimate users.
Bot Attacks: Uses automated bots to scrape data, commit fraud, or disrupt services.

Radware’s Web Application Firewall Solution

Radware’s web application firewall offers a multi-layered approach to web application security, combining signature-based detection with behavioral analysis and machine learning. This enables it to effectively block known threats while also identifying and mitigating emerging attacks.
