  • Research time line (in year) of the individual topics **

  • Security and Privacy ChallengesThe massive concentrations of resources and data present a more attractive target to attackers

    The challenges are not new but Cloud computing intensifies them

    **

  • Technical risksResource exhaustionIsolation failureCloud provider malicious insider, abuse of high privilegeManagement interface compromiseIntercepting data in transitData leakage on up /download, intra- cloudInsecure or ineffective deletion of data Distributed Denial of service DDoSEconomic denial of service EDOSLoss of encryption keysUndertaking malicious probes and scansCompromise service engineConflicts between customer procedures and cloud

  • Policy and organizational risksLock -inLoss of governanceCompliance challengesLoss of business reputation due to co -tenant activitiesCloud service termination or failureCloud provider acquisitionSupply chain failure

  • Legal riskSubpoena and e- discoveryRisk from change of jurisdictionData protection riskLicensing risks

  • Research recommendationsCertification processes and standards for the Cloud

  • Research recommendationsMetrics for security in cloud computingReturn on security investmentsEffects of different forms reporting breaches on securityTechniques for increasing transparency /level of securityLocation tagging, data type tagging, policy taggingPrivacy (data provenance) tracing data end to endEnd to end data confidentiality in the cloud and beyond:Encrypted search (long term)Encrypted processing schemes (long term)Encryption and confidentiality tools for social applications in the cloudTrusted computing in clouds, trusted boot sequence for virtual machine stackStandardization etc.

  • Legal recommendationsLegal issues to be resolved during the evaluation of the contracts (ULA User Licensing Agreement, SLA Service Level Agreement)Data protectionData securityData TransferLaw enforcement accessConfidentiality and non disclosureIntellectual propertyRisk allocation and limitation of liabilityChange of control
