2 Cloud Computing management

9.2 Secure data management of the SaaS replication model in inter-cloud

It is required that the CSP provide functionalities of data integrity management to check whether the data is
identical to that of other CSPs.
It is recommended that the CSP provide to CSCs secure application program interfaces (APIs) to access SaaS
securely.

9.3 Secure data management of the SaaS partition model in inter-cloud
It is required that the CSP provide functionalities for data identity management for software logic to find
appropriate data and avoid data duplication among SaaSs.
It is recommended that the CSP provide cloud storage support data encryption functionalities to protect data.

9.4 Secure data management of the SaaS data partition model in inter-cloud

It is required that the CSP provide merging functionalities to incorporate new data into an already existing
dataset.
It is recommended that the CSP provide functionalities for integrated key management among CSPs so that
encryption/decryption SaaS data can merge.

10 Security considerations
Security aspects for consideration within the cloud-computing environment, including inter-cloud
computing, are addressed by security challenges for CSPs as described in [ITU-T X.1601], which analyses
security threats and challenges, and describes security capabilities that could mitigate these threats and meet
the security challenges.
