Cloud Storage Security Audit System

In response to the problem of unauthorized distribution of internal files to external email addresses, it is possible to construct a system to monitor and manage the corresponding threats in order to prevent data leakage. It uses machine learning to automatically identify anomalous patterns of file sharing by considering the behavior and clickstream frequency and time. The Permission Verification System also has the option which compares sender and recipient email, if the domain does not match it will not allow the sharing of documents. An Activity Logging Module also takes the form of a record keeping system where all sharing activity and change in permission is recorded as well. For testing and validation purpose, the Sample Log Generator generate the sharing activity log in simulated environment. In the last step, Security Audit Documentation gives a comprehensive coverage of the studying system organization, parts, uphold security policies and procedures, and directions for next audits. Lastly, the integration of these systems also enhances data security, particularly by controlling file sharing, policy compliance, detection of threats, and maintaining a full record for a security audit.
