Amazon WAF

AWS WAF is a security service that safeguards web applications from online threats.

It allows users to create rules and policies to filter and monitor HTTP/HTTPS traffic, mitigating common web exploits. WAF provides protection against malicious activities, enhancing the security of web applications hosted on AWS.

AWS WAF allows users to create custom rules to filter and monitor HTTP and HTTPS traffic, providing fine-grained control over web application security. This customisation enables organisations to tailor protections to their specific needs, addressing unique threats. It also defends against common web exploits, such as SQL injection and cross-site scripting (XSS), shielding applications from known attack vectors. As a managed service there are constant updates based on threat intelligence to ensure protection against emerging threats.

Other benefits include real-time monitoring and alerting, supporting the rate limiting and IP blacklisting and aiding compliance efforts by providing detailed logs and metrics, facilitating audit trails and reporting.

Integration capabilities with other AWS services provide a seamless security ecosystem.

WAF can be combined with AWS CloudFront for content delivery and AWS Application Load Balancer for traffic distribution.

Combining AWS WAF with AWS Shield for adds DDoS protection functionality, creating a comprehensive defence strategy.

AWS WAF is often employed in conjunction with content delivery networks (CDNs) like AWS CloudFront and load balancers for comprehensive traffic management and protection. It's valuable in scenarios where regulatory compliance is crucial, offering detailed logging and reporting for audit purposes.

WAF is instrumental in protecting against DDoS attacks through manual or automated IP blacklisting, providing an additional layer of defence for business-critical applications. With its customisable rule sets, it caters to unique security requirements, adapting to specific application architectures.
