Cloud based emails boundaries and vulnerabilities

Since there is significant increase in adoption of cloud computing, securing users emails is also a growing concern. This paper reviews the boundaries, privacy, vulnerabilities, varying legislations of cloud based emails, and how to mitigate such to provide reliable and secure cloud based email services for users and organizations. We propose a new framework to improve security of cloud based email messages: Intelligent Cloud Based Email Encryption and Decryption System (ICLEEDS). The goal is to encrypt content of email mail messages from users´ mail box before being sent. The intelligent machine learning encryption system helps to protect users against email interception, re-construction, phishing attacks, relaying of previous messages, spoofing, eavesdropping and provide high level of privacy.
