What is the AWS web application firewall?
AWS WAF is a web application firewall that helps to protect your web application or API from common web exploits and other dangerous bots that can affect availability, compromise security, or consume excessive resources.
AWS web application firewall (full form – AWS WAF) gives you control over how your traffic reaches your applications, allowing you to create security rules that control the bot’s traffic and prevent common attack patterns, such as SQL injection or cross-site scripting.
You can also customize the rules that filter out specific traffic patterns. You can quickly start using Managed Rules for AWS WAF, a pre-configured set of rules managed by AWS or AWS Marketplace Sellers to address issues such as OWASP Top 10 security risks and automated bots that consume additional resources, may cause skewed metrics, or downtime. These rules are updated regularly as new issues emerge.
AWS web application firewall includes a full-featured API that you can use to automate the creation, deployment and maintenance of security rules.
You can use Amazon CloudFront to deploy AWS WAFs as part of your CDN solution, the application load balancer that runs on your web server or origin server running EC2, the Amazon API Gateway for your REST APIs, or your GraphQL APIs. It is running on AWS AppSync.
