AWS WAF (Web Application Firewall)

by topic_admin

AWS WAF is a web application firewall which permits clients to write application specific principles which increase security and application availability by blocking shared web attacks which try to exploit vulnerabilities.

Using customizable web security guidelines, clients can define which traffic ought to be allowed to get the web application and which ones ought to be blocked. According into AWS, WAF “makes it easy to create rules that block common web exploits like SQL injection and cross-site scripting.”

AWS has tightly integrated the firewall with its monitoring instrument Amazon CloudWatch and content delivery system AmazonCloudfront. This enables users to monitor real-time metrics and receive alerts when the system is under assault. Since Amazon CloudFront enables custom origins, AWS WAF may be utilized to guard sites hosted inside and outside of AWS.

Getting began on WAF is simple since there is not any additional applications to be deployed. Customers simply have to empower AWS WAF on the right source.


Do it and use it several times: WAF enables IT teams to write a centralized set of principles and deploy them across multiple applications. You produce one set of principles and use it on as many applications as you need, instead of writing principles for every individual application.

Reduce friction between growth and security groups: Often there is a knowledge gap between groups which build the application and teams which protected the application. Handoffs may be time consuming. Since WAF could be set up and manged via API’therefore, development teams can tackle security issues prior to and during the installation procedure. The ability to deal with security at the development phase will decrease the complexity of handoffs.

Keep a close attention: AWS WAF’s tight integration with AmazonCloudwatch gives users access to real-time metrics, ability to catches raw requests with details concerning IP addresses, and geo locations, URIs, User-Agent and Referers. Customers can create alerts which have triggered when a particular threshold is exceeded or when a specific kind of attack happens. The logs may be utilized to assess and improve security if a breach occurs.

Automatic Deployment: AWS clients can utilize CloudFormation templates to define security rules to their application, and also to deploy and provision WAF automatically.

How does it function: “AWS CloudFormation template automatically launches and configures the AWS WAF settings and protective features you choose to include during initial deployment.” – AWS
