Amazon Web Application Firewall

Amazon Web Application Firewall (AWS WAF) is a fully managed security service that helps protect web applications from common web exploits that could affect the availability, performance, or security of the application. AWS WAF is designed to be easy to use and manage, and it provides a number of features that make it effective at protecting web applications.

One of the key features of AWS WAF is its ability to allow or block requests based on certain criteria. You can use AWS WAF to set rules that specify which types of requests should be allowed or blocked, based on things like the IP address of the requestor, the type of browser being used, or the specific parameters being passed in the request. This allows you to block malicious or unwanted requests and ensure that only legitimate traffic reaches your web application.

AWS WAF includes a library of pre-built rules that you can use to protect against common web vulnerabilities, such as SQL injection attacks and cross-site scripting (XSS) attacks. You can also create your own custom rules to protect against specific threats or to enforce your own security policies.

AWS WAF integrates seamlessly with Amazon CloudFront, the AWS content delivery network (CDN), and Application Load Balancers, allowing you to apply WAF rules at the edge of the network to protect against attacks before they reach your web applications. This can help improve the performance of your web applications by reducing the number of requests that need to be passed through to your application servers.
