Unveiling the Distinctions: Web Application Firewall (WAF) vs. Next-Generation Firewall (NGFW)
In the realm of cybersecurity, two formidable guardians stand tall: the Web Application Firewall (WAF) and the Next-Generation Firewall (NGFW). While both serve as crucial defenses against cyber threats, they possess distinct functionalities tailored to address specific aspects of network security. Let's embark on a journey to unravel the disparities between these two stalwarts and understand their respective roles in safeguarding digital assets. 1. Understanding the Core Functions: 1. Web Application Firewall (WAF): Designed specifically to protect web applications from various attacks such as SQL injection, cross-site scripting (XSS), and other OWASP Top 10 threats. Operates at the application layer (Layer 7) of the OSI model, inspecting and filtering HTTP and HTTPS traffic.
