By CloudDefense.AI Logo

Shield is an essential component of Amazon Web Services (AWS) that provides advanced protection for applications running on the AWS cloud. It is designed to safeguard web applications from various types of malicious attacks, such as Distributed Denial of Service (DDoS) attacks. With Shield, businesses can strengthen their security posture and ensure the availability of their applications.

AWS Shield offers two levels of protection: AWS Shield Standard and AWS Shield Advanced. AWS Shield Standard is provided to all AWS customers at no additional cost. It defends against the most common and frequently observed DDoS attacks, automatically detecting and mitigating them. This ensures that applications stay online and accessible to legitimate users, even during an attack.

For more comprehensive protection, AWS Shield Advanced is available as a premium service. It includes all the features of Shield Standard and provides additional capabilities to counter more sophisticated and larger-scale attacks. Shield Advanced offers enhanced DDoS protection, including real-time monitoring, threat intelligence, and DDoS cost protection. It also provides access to the AWS DDoS Response Team (DRT) for guidance and support during an attack.

By leveraging AWS Shield, businesses can benefit from a robust and scalable security solution without the need for elaborate infrastructure investments. AWS handles the complexity of DDoS protection, allowing organizations to focus on their core business activities. Shield provides automatic protection, minimizing the impact of attacks and reducing downtime.

To summarize, AWS Shield is a cloud security service that offers comprehensive protection against DDoS attacks. It comes in two tiers – Shield Standard and Shield Advanced – and provides automatic detection and mitigation of attacks, ensuring the availability of applications on the AWS cloud. With Shield, businesses can confidently embrace the benefits of cloud technology while minimizing the risk of cyber threats.
