This is where, the AWS WAF Test helps!īy default, this test automatically discovers the rules configured in the AWS Web Application Firewall. Administrators can then proceed to fine-tune these rules/WebACLs, so that their mission-critical applications are more secure. In the process, administrators can isolate ineffective or incorrectly configured rules/WebACLs and the security threats they pose. Periodically, administrators must track the requests allowed and/or blocked to understand whether/not your web aplications/sites are well-protected against malicious attacks. Once a request meets one of the conditions defined in your rules, AWS WAF instructs the underlying service to either block or allow the request based on the action you define. If you add more than one rule to a WebACL, a request needs to match only one of the specifications to be allowed, blocked, or counted. These services receive requests for your web sites and forwards those requests to AWS WAF for inspection against the rules configured in the WebACL. You can then associate the WebACL with an Amazon CloudFront distribution or an Application Load Balancer (ALB) - services that AWS customers commonly use to deliver content for their websites and applications. You also need to specify a default action for a WebACL. You can add one or more rules to a WebACL, and associate each rule with an action (allow/block/count) - for example, block requests from specified IP addresses or block requests from specified referrers. A rule identifies the requests that you want to allow, block, or count. AWS WAF is a web application firewall that helps protect your web applications from common web exploits that could affect application availability, compromise security, or consume excessive resources.ĪWS WAF gives you control over which traffic to allow or block to your web applications by defining customizable web security rules.
