AWS WAF
AWS WAF (Web Application Firewall) is a managed service that helps protect web applications from common web exploits and bots by filtering and monitoring HTTP/HTTPS traffic. It allows developers to create custom rules to block malicious requests, such as SQL injection or cross-site scripting attacks, and integrates seamlessly with other AWS services like CloudFront, Application Load Balancer, and API Gateway. The service provides real-time metrics and logs for security monitoring and compliance.
Developers should use AWS WAF when deploying web applications on AWS to enhance security against OWASP Top 10 threats, such as injection attacks and DDoS attempts, especially for high-traffic or sensitive applications like e-commerce sites or APIs. It is ideal for teams needing a scalable, managed firewall without maintaining infrastructure, and it complements AWS Shield for DDoS protection in cloud environments.
