AWS Web Application Firewall (WAF)

Information Technology > Web security

Description

AWS Web Application Firewall (WAF) is a security service that protects web applications from common web exploits like SQL injection and cross-site scripting (XSS). It allows you to create rules that block, allow, or monitor (count) web requests based on conditions you define. These conditions might include IP addresses, HTTP headers, HTTP body, URI strings, SQL code, or script code. AWS WAF can be integrated with other AWS services for enhanced security and monitoring. Advanced users can automate WAF setup using AWS SDKs and Command Line Interface (CLI), and implement security automations. Understanding AWS WAF requires knowledge of its features, use cases, pricing model, and how to troubleshoot issues.
