2. Introduction ▪ Takuya Onda – eureka, Inc. – SRE team Engineer Lead
3. Agenda ▪ 1. Security overview and problems ▪ 2. Continuous vulnerability detection ▪ 3. Continuous change management ▪ 4. Access control and developer efficiency
4. Security Problems ▪ Vulnerability management – Detection / Reporting ▪ Change management – Procedure to rollout new patch to production ▪ Access control management – SSH / DB / Monitoring
5. What we really want to achieve?
6. 1:Automated Detection and Prevention & Reporting ▪ External attack – DDOS / Penetration / Injection ▪ Internal vulnerabilities – Network / Middleware / Application
7. Solution: Standing on the Shoulders of Giants ▪ Akamai WAF – Risk grouping / reputation control – Automated detection / prevention ▪ AWS Inspector – Host based security scanner by AWS – Scheduled implementation and reporting via lambda
8. Solution: Standing on the Shoulders of Giants
9. 2: Easy & Safety Process for Patching ▪ Unified Patching Process – No manual modification ▪ Frequent changes by replacing, not updating – Progressive rollout by replacing instances – Much easier for testing
10. Solution: Patched Image & Blue Green Rollout ▪ Patched Golden Image by Packer x Ansible – Same role & steps for staging / production ▪ ASG on ELB + CodeDeploy by Terraform – Rollout new AMI by create new ASG and replace old one – Treat instances as disposable – Fully codenized Infrastructure
11. Solution: Patched Image & Blue Green Rollout
12. 3: Compatibility between Access Control & Devs Efficiency ▪ No SSH – Exterminate reason that developers need direct access ▪ Resolve complicated procedures into simple ones – Want to provide all info about production for developers
13. Solution: Log Consolidation for No SSH World ▪ Definition of deployment completion – Dev just needed to know whether their deploy really was ok ▪ Log consolidation via StackDriver / CloudPubSub – Visualize all app-logs and set regex-based error alert – Also used for audit log consolidation
14. Solution: Log Consolidation for No SSH World
15. Solution: Log Consolidation for No SSH World
16. Solution: Log Consolidation for No SSH World
17. Summary
18. Summary ▪ Security overview and problem – Categorized into 3 major problems ▪ Continuous vulnerability detection – Akamai WAF / AWS Inspector ▪ Continuous change management – Packer x Ansible x Terraform for progressive patch rollout ▪ Access control and developers efficiency – StackDriver for log consolidation
