AWS Shield is a DDoS protection service that is focused on mitigating the negative effects of distributed denial-of-service (DoS) attacks by automatically detecting and responding to such attacks.
Amazon Shield Standard protects against all known layer 4 DDoS attacks and it integrates seamlessly into the entire AWS environment. Additionally, it offers static threshold DDoS protection and inline attack mitigation capabilities
AWS Shield Advanced includes a support team, AWS Wireless Application Firewall (WAF), and AWS Firewall Manager. It offers advanced DDoS detection and mitigation techniques and integrates with AWS WAF to provide an additional layer of DDoS protection
To mitigate DDoS attacks, an organization can implement a resilient DDoS-resistant architecture using edge location DDoS mitigation. AWS provides Amazon CloudFront, Amazon Global Accelerator, and Route 53 for this purpose
Best security practices such as reducing the attack surface area, implementing rate-limiting rules, and enforcing bot control, play a key role in DDoS protection
Regularly updated patching systems, encrypting data, employing robust authentication and authorization mechanisms, and having an incident response plan in place are crucial for safeguarding cloud resources against DDoS attacks
Organizations should run a simulated DDoS attack in production traffic and/or conduct a synthetic simulated DDoS attack with the AWS Shield Response Team to ensure they are well prepared to respond effectively in real-world DDoS attack situations
The AWS Certified Security Specialty certification is helpful in equipping professionals with the necessary knowledge and skills to proactively protect their cloud environments from DDoS attacks.
