If you want your application to contain specific validation tokens in headers, you can specify such rules in the WebACL associated with the Application Load Balancer. With AWS WAF, you can create security rules that control bot traffic and block common attack patterns such as SQL injection or cross-site scripting (XSS). AWS provides two kinds of load balancers: Network Load Balancer (NLB), which works on the L3/L4 layer of the networking stack, and Application Load Balancer (ALB), which works on the L7 application layer. Custom rules: Not all attacks can be blocked using managed rules. To mitigate this potential security risk, we should associate AWS WAF with API Gateway to address issues specific to this use case and this layer of the architecture stack. Depending on the implementation of the rate-limiting logic for that specific CDN, it might be possible to be quite efficient since the number of IPs that can use a particular PoP is a much smaller subset of all the customers accessing that service. Ideally, it’s best to put such rules on the edge to avoid massive data transfer costs, but it can also mean internal services can bypass such limits. Using AWS WAF with CloudFront, API Gateway, and Load Balancer created a robust and reliable architecture. Authentication validation systems can be susceptible to Pass-The-Hash attacks, where the attacker does not need to de-hash the hashed password but tries to restart the session using stolen hashed passwords. Non-rate-limiting but low-effort high-volume attacks like Log4J or SQL injection attacks based on most common patterns can be best blocked at the Edge itself. Managed rules: Managed rules block common, well-known attack patterns. If your application uses JWT for token-based authentication, the WAF rules can focus on such logic when associated with API Gateway. Application Load Balancer: These are regional load balancers sitting inside the AWS network, probably inside your subnet, and have the responsibility of spreading the traffic load across multiple instances of your web server. Attackers use application code weaknesses to inject harmful SQL statements, which could lead to unauthorized access to important data. Software-as-a-service (SaaS) has become a giant industry, taking care of hosting services used by customers by upgrading, scaling, and securing customer data. If your application requires specific headers to be present, you can allow them to be listed as the first rule of your WebACL and set the default action of WebACL to block. We can tailor specific rules to specific stages and resources to create a seamless and efficient security posture. Malicious actors seek to steal customer data or DDoS-ing the service to prevent legitimate customers from accessing the website. API Gateway is a fully managed cloud service that lets developers build and deploy APIs, the most common being REST APIs. API Gateway: The API Gateway is the place where we would address the specific attacks related to API Design. Such restrictions can be implemented in application logic, too, but if you want to block an explicit list, then the WAF on the API Gateway can be a good choice. Traditional web application firewalls usually do not effectively handle these complicated challenges, particularly in cloud-native settings where applications are spread out in different native services and regions. These assaults aim to inundate web applications by sending them excessive traffic from numerous compromised machines, rendering services inaccessible to authorized users. (2022). Denial of Service Attack Classification Using Machine Learning with Multi-Features. Code Injection attacks should be addressed in the code itself as we use code to validate the input data. Not everything can be blocked at the WAF rules level since it can be too complex to implement using the standardized WAF syntax.
