Shield Advanced protection issues.

Shield Advanced is designed to protect against DDoS (Distributed Denial of Service) attacks. If you're facing problems with this service, here are some steps you can take to troubleshoot the issues:

1. Review AWS Shield Dashboard:
   • Log in to the AWS Management Console, go to the AWS Shield console, and review any alerts or notifications regarding DDoS attacks. This might provide insights into the nature of the attacks.
2. Monitor AWS CloudWatch Metrics:
   • Check the CloudWatch metrics related to Shield Advanced. This can provide detailed information about the traffic patterns and any anomalies that might be indicative of a DDoS attack.
3. Analyze Access Logs:
   • Analyze your application's access logs to look for any suspicious traffic patterns or spikes in traffic. This can help identify the source and nature of the DDoS attack.
4. Enable AWS WAF (Web Application Firewall):
   • Consider enabling AWS WAF in conjunction with Shield Advanced. WAF can provide additional protection by filtering out potentially malicious traffic.
5. Increase Shield Protection Level:
   • Shield Advanced offers different protection levels (Standard and Advanced). If you're under attack, consider escalating the protection level to Advanced, which provides more robust protection against larger and more sophisticated attacks.
6. Engage AWS Support:
   • If you're under a sustained or complex attack, contact AWS Support. They can provide additional guidance and assistance in mitigating the attack.
7. Review AWS Shield Documentation:
   • AWS provides detailed documentation on Shield and DDoS protection. Reviewing the documentation might provide specific steps or best practices for handling different types of attacks.
8. Review Security Groups and NACLs:
   • Ensure that your security groups and network access control lists (NACLs) are configured appropriately to only allow necessary traffic and block any suspicious or malicious traffic.
9. Optimize Content Delivery Network (CDN) Configuration:
   • If you're using a CDN (such as AWS CloudFront), ensure it's configured optimally. CDNs can help absorb and mitigate certain types of DDoS attacks.
10. Incident Response Plan:
    • Have an incident response plan in place that outlines the steps to take in the event of a DDoS attack. This should include contacting AWS Support, monitoring logs, and implementing mitigation strategies.
11. Review AWS Trusted Advisor Recommendations:
    • AWS Trusted Advisor can provide recommendations for optimizing your AWS infrastructure. Check if there are any relevant recommendations related to DDoS protection.
12. Implement Rate Limiting and Throttling:
    • Implement rate limiting and throttling mechanisms within your application to mitigate the impact of excessive requests.

Remember to document any observations, actions taken, and the outcomes for future reference. Additionally, consider consulting with a security expert or a professional with experience in handling DDoS attacks if needed.
