What is the function of AWS WAF?

The function of AWS WAF, or AWS Web Application Firewall, revolves around providing protection to web applications from common web threats and vulnerabilities. This includes safeguarding against attacks such as SQL injection, cross-site scripting (XSS), and other exploits that can compromise web application security. By using AWS WAF, organizations can set rules to allow or block traffic to their web applications, thereby enhancing their security posture.

Organizations benefit from this service because it helps to ensure the confidentiality, integrity, and availability of web applications while also enabling compliance with various security standards. AWS WAF allows users to customize their security rules and integrates seamlessly with Amazon CloudFront and Application Load Balancer, making it an integral component of a robust web security strategy.

The other options describe different AWS functionalities but do not pertain to the primary purpose of AWS WAF. Thus, while it’s essential to understand the broader AWS ecosystem, focusing on the specific role of AWS WAF highlights the critical need for web application security in today’s digital landscape.
