Benefits of AWS WAF

You now know how to use AWS WAF. It's time to consider the advantages of using it. Some of the benefits of are as follows using Amazon Web Application Firewall:

  • This service simplifies and secures the deployment and management of applications held on Amazon CloudFront, Application Load Balancer for your CDN solution, Amazon API Gateway for REST APIs, or AWS AppSync for GraphQL APIs.
  • It protects web applications from threats by filtering traffic based on the rules you specify. WAF supports thousands of rules and can validate any component of a web request with minimal latency effect on incoming traffic. As a result, AWS WAF latency is limited.
  • AWS WAF rules can be dispersed and changed in minutes, allowing you to improve security quickly.
  • Managed rules are synchronised automatically as new impacts emerge, allowing you to spend more time developing applications rather than worrying about security.


How Does AWS WAF Work?

Before you can understand how AWS WAF works, you must first acknowledge the Web ACL, WAF Conditions, and WAF Rules, which are AWS Web Application Firewall components. FITA Academy also offers placement Assistance with the course completion certificate in AWS Course in Coimbatore.



A Web Access Control List (Web ACL) is a set of rules that allows you to direct how an Amazon API Gateway API, Amazon CloudFront distribution, or AWS WAF load balancer responds to web requests. A web ACL can contain up to ten rules, and users can specify whether to accept or reject firewall requests based on the circumstances.


WAF Conditions

Criteria define the fundamental characteristics that you want the WAF to look for in web requests. Conditions such as IP match, string match, SQL injection, and others can be defined. You should align the terms so that they specifically address the requests you want to accept, reject, or count.


WAF Rules

The Rules include terms and conditions. If users use more than one condition per rule, they must fulfil request variables in all conditions, which is permitted or denied. WAF Managed Rules is a straightforward method for implementing pre-configured rules to protect your applications from common threats such as software vulnerabilities. AWS Marketplace security providers automatically configure all managed rules. Join AWS Training in Bangalore with Career Guidance and Placement Assistance.
