Malicious scripts are embedded in online applications by attackers to exploit security flaws (known as Cross-site scripting (XSS)).

We use AWS WAF rules on the basis of certain criteria like – Mixed RulesĪWS Firewall Manager and Shield Advanced have their own rule groups that they own and control. These are those rules which are created and maintained by the user only. Managed rule groups are created and maintained for you by AWS Managed Rules and AWS Marketplace merchants. There are basically 3 types of Rules Groups – Managed Rule Group When a request fulfills one of your rules’ conditions, AWS WAF advises the underlying service to block or accept the request, depending on the action you specify. When the associated service receives requests for your websites, it sends them to AWS WAF to be inspected for compliance with your rules. In order to provide you with more flexibility, these rules can be enforced on a per-application basis. IP addresses, HTTP headers, HTTP body, URI strings, SQL injection, and cross-site scripting are among the conditions, You can either utilize AWS’s default security rules or create your own. WAF can act more powerful with custom rules according to the organization’s needs.ĪWS WAF is a web application firewall that helps protect web applications from threats by allowing you to set up rules that allow, reject, or count web requests based on parameters you specify. Generally, attackers use proxy to anonymize their identity, in the same way, a WAF protects the web app server details from a potentially dangerous client by acting as a reverse proxy.Ī WAF is controlled by a set of rules known as policies. What is a Web Application Firewall?Ī web application firewall (WAF) secures your web apps by filtering, monitoring, and as well as blocking threatening requests.Īs you may know, this is the app’s first line of defense against internet traffic. Websites, online apps, and servers, which are important components of today’s organizations, therefore, are high on the hit list of cyber-attackers looking for new and inventive ways to launch attacks.Īs a result, web app security measures and tactics are in high demand to counter these threats, and a Web Application Firewall (WAF) has become an integral part in order to defend critical assets of an organization. We are witnessing remarkable technology developments that are transforming the way the world functions in only a few years.
