AWS WAF gives you control over how traffic reaches your applications by enabling you to create security rules that control bot traffic and block common attack patterns, such as SQL injection or cross-site scripting. AWS WAFĪWS WAF is a service offered in security domain which is highly integrable with AWS Application Load Balancers (ALBs), Amazon CloudFront (CDN), Amazon API Gateway or AWS AppSync for your GraphQL APIs.

In cloud hosting era, WAF has become increasingly integral part of IT security where most of the applications are Web or API exposed to the Internet. By inspecting HTTP traffic, it can prevent attacks exploiting a web application's known vulnerabilities, such as SQL injection, cross-site scripting (XSS), file inclusion, and improper system configuration. What is WAFĪ web application firewall (WAF) is a specific form of application firewall that filters, monitors, and blocks HTTP traffic to and from a web service. Hence deploying all required security levers in Day 0 is crucial for any workload hosting in Cloud and WAF should be the minimum required control among them. The probability of you in the limelight of cyber criminals are very high if you host your workloads in public cloud, as bad actors know the cloud providers hosting IP space and knowledgeable on existence of your critical data in the cloud. Web Application Firewall (WAF) was protection suits actively part of the network and security stream since last couple of years which enriches the protection mechanisms.

Cyber criminals have modernized their strategy and tools, hence there is an absolute need for modern security tools for protection.Īlthough modern methodologies and attack vectors are increasing, according to, Cross-site Scripting (XSS) continues to be the most awarded vulnerability type with US$4.2 million in total bounty awards, up 26% from the previous year.Īccording to geekflare, web application threats list, Injection attacks is in the 3rd position of common threat space for web applications. In the modern age of sophisticated cyberattacks and digital innovation, it is vital for businesses to understand their threats and what their security defense need to be. A perimeter firewall was a stronger defense mechanism in later 2000. This blog post is to help AWS customers to do a quick start of AWS WAF (Web Application Firewall) adoption to their architecture by understanding the bare minimum policy sets to start with.
