What can AWS WAF help you do with web requests?

AWS WAF (Web Application Firewall) is specifically designed to protect web applications from common web exploits that could affect application availability, compromise security, or consume excessive resources. The main function of AWS WAF is to allow users to create security rules that can block or allow HTTP and HTTPS requests based on customizable conditions that include IP addresses, HTTP headers, URIs, and query string parameters. This flexibility enables you to define fine-grained access controls that suit the specific security needs of your application.

By utilizing AWS WAF, organizations can tailor their security measures to effectively mitigate risks and prevent malicious traffic from reaching their applications. This not only enhances the security posture of web applications but also allows legitimate traffic to proceed without interruption. Therefore, the ability to block or allow requests based on customizable conditions accurately describes a primary capability of AWS WAF.
