@ Sergio Castro, Thanks for your suggestions, I worked with Cloud Security Alliance in their Cloud Controls Matrix V.1.14 and at present, cloud organizations are implementing COBIT and ISO etc for their information security but these standards are for traditional IT not particular for Cloud Computing.
The CSA Matrix also taken from different standards and as per my research, these standards does not provide 100% information security measures to Cloud organizations.
The ANNEX A is in the final pages of ISO 27001:2013. Annex A is a list of great importance to carry out checks and implementations related to information security. It is a list of 114 controls (best practices), grouped into 35 control objectives, which are grouped into 14 key points, labeled from A.5 to A.18. You can find the implementation of Annex A in the ISO 27002:2013.
I worked on ISO 27001:2005 to develop "SLA based information Security Metrics in Cloud Computing". My book on this title is also available on internet but i do not have ISO 27001:2013 version. Would you please send me on my mail box so i may also work on it.
