AWS Technical Essentials Practice

AWS Shield is a security service that provides protection against Distributed Denial of Service (DDoS) attacks, which are a common threat to web applications. By leveraging AWS Shield, users can benefit from advanced detection and mitigation techniques that safeguard their applications and enhance overall resilience. This protection is crucial for maintaining the availability and security of applications that are hosted on AWS.

In contrast, basic firewalls provide a fundamental level of security by controlling incoming and outgoing network traffic based on predetermined security rules, but they do not specifically offer advanced DDoS protection. AWS Direct Connect is primarily a service that provides dedicated network connections from on-premises to AWS, enhancing performance and reducing costs, but does not focus on application security. AWS Marketplace offers a variety of third-party applications and services, which can include security tools, but it does not provide direct security features itself.

Therefore, AWS Shield stands out as a dedicated service specifically designed to enhance application security by protecting against significant threats like DDoS attacks.
