Security has been a critical concern for most businesses in recent years. Fortunately, there are a variety of services that can assist you in improving the overall security of your AWS setup. AWS WAF (Web Application Firewall) is a firewall that protects your web application server from a variety of attacks on the Internet.

The AWS Web Application Firewall (WAF) is a security utility that aids in protecting your application from web-based threats. WAF keeps track of and regulates odd bot traffic, as well as blocking popular attack patterns like SQL Injection and Cross-Site Scripting. It also allows you to keep track of HTTP and HTTPS requests sent to an Amazon API Gateway API, Amazon CloudFront, or an Application Load Balancer.

• Using an IP address from which the request comes, Amazon WAF allows you to regulate your content.

• Access control lists, rules, and Rule Groups are the three components that make Amazon WAF work.

• Web ACL capacity units (WCU) are managed by Amazon WAF for rules, rule groups, and web ACLs.

• You can automate the creation, implementation, and maintenance of security rules with Amazon WAF’s full-featured API.

Common Web Attacks

Before protecting your applications, you need to know the most common web attacks mention below.

DDoS (Distributed Denial-of-Service) attacks: This is the most popular type of assault. Attackers use bulk requests to overburden an application. In this attack, which uses over one unique IP address or machine, tens of thousands of hosts infected with malware get exploited. This slows down the application and lowers the brand’s worth dramatically.

SQL injections : It is a type of code injection that has the potential to ruin your SQL database. Attackers can conduct malicious SQL queries on your web applications.

Croos-site Scripting: If your application is vulnerable to cross-site scripting, the attacker can launch or inject harmful scripts as a browser side script. These scripts can even rewrite the HTML pages’ content.

AWS WAF Features

Amazon Web Application Firewall offers lots of features to its users mentioned below.

Protection Against Web Attacks: AWS WAF includes various rules to analyse any piece of a web request with minimal latency impact on incoming traffic. AWS WAF protects web applications from risks by filtering traffic based on the rules that have been set up.

Create Rules As Necessary: AWS WAF is a versatile and important tool for securing application infrastructures. This is because it allows users to create rules based on their needs and vulnerabilities that they want to avoid. It is a fantastic solution for securing any web application environment at the business level.

Web traffic filtering: WAF enables users to create web traffic filtering rules. IP addresses, HTTP headers, HTTP content, and URI strings are all filtered from a web request.

Flexible AWS Services Integration: The AWS Web Application Firewall makes it simple to integrate with other AWS services such as Amazon EC2, CloudFront, and Load Balancer.

Monitor Rules: AWS Web Application Firewall allows us to define, examine, and customise rules in order to prohibit unknown attracts.
