Any Organization in the World need to prepare themselves before they move to the cloud, i.e. cloud security risk assessment. It is all about managing your risks if you accept to move to the cloud and understanding the risks and benefits should be essential part of any organization thinking to move to cloud infrastructure.

  23. CSA – Cloud Assessment Framework Master of Information
  24. Sample Assessment Governance • Best opportunity to secure cloud engagement is before procurement – contracts, SLAs, architecture • Know provider’s third parties, BCM/DR, financial viability, employee vetting • • • • Identify data location when possible Plan for provider termination & return of assets Preserve right to audit where possible Reinvest provider cost savings into due diligence Master of Information
  25. Sample Assessment Operation • Encrypt data when possible, segregate key mgt from cloud provider • • Adapt secure software development lifecycle • Logging, data exfiltration, granular customer segregation • • Hardened VM images Understand provider’s patching, provisioning, protection Assess provider IdM integration, e.g. SAML, OpenID Master of Information
  26. Cloud Control Matrix Tool Controls derived from guidance Rated as applicable to SP-I Customer vs Provider role Mapped to ISO 27001, COBIT, PCI, HIPA A Help bridge the “cloud gap” for IT & IT auditors Master of Information
  27. Cloud Adoption - Challenges Market Perception toward cloud Master of Information
  28. Case Study – SSH decrypted (VM)  Based  Key on Brian Hay and Kara Nance paper Motivation:  Malware encrypted communication with C & C  Law Enforcement capability to monitor deployed cloud and enterprise VM  Novelty:  Visibility into cryptographically protected data and communication channels  No modifications to VM Master of Information
  29. Case Study – SSH decrypted (VM)  Approach:  Identification (Processes of crypto lib and calls made to the lib)  Recovery (input to & output to – crypto functions)  Identification (crypto keys)  Recovery (crypto keys above)  Recovery of plaintext (using recovered keys)  How to  Minimum described in the paper  Keywords  Xen platform, libvirt, sebek techniques Master of Information
  30. Case Study – SSH decrypted (VM)  Sebek Installation & Operation  http://www.honeynet.org/project/sebek  http://www.sans.org/reading- room/whitepapers/detection/turning-tables-loadablekernel-module-rootkits-deployed-honeypotenvironment-996  http://vimeo.com/11912850  Limitation  Sebek modules can be detected with rootkit detection tools Master of Information
  31. Case Study – SSH decrypted (VM) Master of Information
  32. Case Study – SSH decrypted (VM) Master of Information
  33. Case Study – SSH decrypted (VM) Master of Information
  34. Case Study – SSH decrypted (VM) Master of Information
  35. Safe Cloud – is it possible?  Big Question: Is it possible to have a safe cloud? (https://www.safeswisscloud.ch) Master of Information 35
  36. New Development – Cloud Crypto https://itunes.apple.com/us/app/cloudcapsule/id673662021 Master of Information 36

  39. Conclusion is no 100% security  It is all about managing risks  There  It all depends on single, exploitable vulnerability (the weakest link)  Cloud greatest risk is still the insiders  CSA Risk Assessment helps to bridge the gap between the Cloud model and compliance  Uncovering crypto keys in the cloud is possible  important to malware research Master of Information
