THANK YOU FOR SUBSCRIBING
Cybercrime is not only something that threatens the technology circle but also disrupts the life of every common man. The WannaCry ransomware attack last May stands a proof for this statement. In such a scenario, data loss and breach have a severe impact on the business and can spoil the reputation. Data leak prevention is considered the most important factor with 88 percent of critical challenges. On the other hand, data segregation and protection has 92 percent impact on security challenges. The growth of cloud applications and IoT devices has led organizations to review their current security methods and employ advanced methodologies. Cloud computing is the next generation Internet-based computing system where data is stored and accessed in a remote server through services provided by the cloud providers such as Amazon, IBM, Google, Microsoft, etc. A well-built cloud storage can provide extensive security regardless of the fundamental security concerns. According to Gartner, cloud computing possesses unique attributes which require risk assessment in data integrity, recovery, and privacy.
The security breach is a major concern when data is processed in a remote location since groups of users are provided access to the data. Therefore, data transmission should be done with utmost care, and security challenges must be addressed before implying cloud computing in an organization as unsafe data transmission may lead to data breaches. To circumvent the risk, data involving storage, transit and the data repositories must be secured. Without strong encryption and distinct credential, it is hard to secure the data in the cloud, however, sharing only encrypted data can improve security.
