摘要：Cloud computing is well - known for delivering information technology services based on internet. Currently, organizations are concerned in affecting their huge records and computation into cloud to collect their major revenue. As cloud storage space is striking a choice for user in trust their data online, it comes with the safety threats and the challenge of defensive their data from not permitted access. Many safety measures controls have been optional by overriding b odies, industry standards etc. as strategy to be implement by cloud storage providers (CSPs) but the complete set of controls cannot be fully implemented due to several challenges such as decreasing ease of use, less user expediency, need of a strong infra structure etc. Therefore, we anticipate the need to apply security based on category of data determined by users. Data categorization provides one of the most basic ways for organizations to determine and assign relative values to the data they possess. Th e process of data categorization allows organizations to categorize their stored data by compassion and business impact in order to determine the risks associated with the data. The proposed security system acclimates well for cloud environment and is also customizable and more reliant to meet the required level of security of data with different sensitivity that changes with business needs and commercial conditions
