Abstract
Data protection in the online environment pertains to the safeguarding of sensitive or important data kept, analyzed, or sent in cloud-based systems. It entails assuring data confidentiality, integrity, and availability, as well as adhering to appropriate data protection requirements. In a nutshell, cloud data protection seeks to protect data against unauthorized access, deletion, or breaches while retaining its accuracy and accessible to authorized users. Research in data protection in the cloud helps address the security and privacy concerns associated with storing and processing sensitive data in cloud-based systems. It explores and develops advanced security mechanisms, encryption techniques, and access controls to protect data from unauthorized access, data breaches, and privacy violations. This is accomplished in the cloud environment using various security measures, encryption approaches, access controls, disaster recovery and backup processes, and constant monitoring and threat detection. The weighted product method approach is commonly used to choose the best data protection in cloud environment. Taken as Alternative Parameter is CCSS1, CCSS2, CCSS3, CCSS4, and CCSS5. Taken as Evaluation parameter is data visibility, data integrity, Maintains compliance, Data security, Data storage. From the result it is seen that CCSS2 got highest rank where as CCSS5 got lowest rank. According to the results, CCSS2 was ranked first. The ranks indicate the relative position or ranking of each category based on their preference scores, with 1st being the highest rank and 5th being the lowest rank.
