OWASP dans le cadre des Midis conférence est heureux d'accueillir, M. Gaëtan Trivino.

Notre conférencier viendra présenter l'influence de la culture devops sur les opérations d'un hébergeur international en particulier pour supporter les réglementations comme PCI DSS.

Biographie :

Gaëtan est DevOps technical leader orienté cloud et automatisation réseau. Il a traversé l'Atlantique avec sa famille pour explorer de nouvelles culture de travail et se lance dans la recherche du meilleur sirop d'érable!

  1. Operate PCIDSS infrastructure using devOps approch

  2. About Me • Gaëtan Trivino • Arrived from France a

    year ago • Working at cloud provider • @gaetantri
  3. Summary • How devOps on PCIDSS infrastructure? – Infra design

    – SoD • Common operations tasks – Alert is trigger • H2M interaction – Log review • security purposes (Internal / External) • Track humans mistakes • Secure coding using OWASP • Ending • Q&A
  4. Why devOps ? Origins of our devOps approch • Large

    scale infrastructure (> 200k VM) • All infrastructures are PCIDSS compliant • PCIDSS process and control so complicated • Human make more mistakes than robots • Scale robot easier to scale humans
  5. Never trust humans • Robots checks humans action before working

    • Track unexpected human operations CMDB Infrastructure configuration Robots Human
  6. SoD DATACENTER Infra Customer Advocates devOps R&D RUN Customer facing

    => Access: production => no Access: automation No customer facing: => Access: automation => no Access: production
  7. 3AM, AN alert is trigger

  8. 3AM, AN alert is trigger Unify alert broker • alerts

    code < 300 trigger automated fixes => traceability • Alerts code > 301 trigger human alerting
  9. 3AM, AN alert is trigger ORICO PCI DSS Zone •

    Connect to VPN • No access to impacted infrastructure
  10. 3AM, AN alert is trigger • Infrastructure details • Last

    automated operations
  11. 3AM, AN alert is trigger • List of possible actions

    integrated with infrastructure context • No need to access production environment

  20. x1 SBG #571 3AM, AN alert is trigger

  21. 3AM, AN alert is trigger • Automated procedure triggered by

    human • Keep what we did on infrastructure traceability
  22. 3AM, AN alert is trigger

  23. 3AM, AN alert is trigger 2 hours later Access deleted

  24. x1 SBG 3AM, AN alert is trigger #571

  25. What’s cool ? • Easy traceability of human and automated

    actions • Simplify access control • Limit risks of access usurpation • Trigger automated procedures are easier to do Challenges • Code has to be efficient and secure • CI/CD
  26. What’s risky? • Code has to be efficient and secure
