E-mail Attachment Sharing Protection

Secure File Sharing: Leveraging SharePoint for Controlled Access

We implemented a secure and controlled solution for sharing sensitive files through email attachments by leveraging SharePoint Portal Server.

Project Scope:

  • The solution is designed to work with both Microsoft Exchange Server and hMailServer email servers.
  • The solution utilizes group-based access control to restrict the sending and receiving of sensitive attachments.
  • Designated groups of users are authorized to share files with specific sources, ensuring controlled access to confidential information.

Project Methodology:

  1. Attachment Identification:
  2. -The solution employs a mechanism to identify sensitive files based on file extensions, file sizes, or specific pre-defined patterns.

  3. Attachment Detachment:
  4. -For identified sensitive attachments, the solution intercepts the email messages and detaches the attachments from the original emails.

  5. Attachment Upload to SharePoint:
  6. -The detached sensitive attachments are securely uploaded to a designated SharePoint Portal Server location.

  7. Attachment Delivery:
  8. -Instead of sending the sensitive attachments directly through email, the solution generates a link to the uploaded attachment on the SharePoint Portal Server.

  9. Secure Access:
  10. -The SharePoint Portal Server repository is secured with stringent access control mechanisms to ensure that only authorized users can access the sensitive attachments.

  11. User Authentication:
  12. -The solution integrates with existing user authentication systems to verify the identity of users attempting to access sensitive attachments.

  13. Access Restrictions:
  14. -Access to specific attachments is restricted based on the user’s group membership, ensuring that only authorized users can access the relevant information.

  15. Tracking and Auditing:
  16. -The solution maintains a comprehensive audit trail of all attachment transfers, including user actions, attachment details, and access timestamps.

Project Benefits:

  • Enhanced Security:
  • -Sensitive files are securely stored and accessed within a controlled environment, reducing the risk of data breaches.

  • Improved Control:
  • -Group-based access control regulates the flow of sensitive attachments, ensuring that only authorized individuals can access confidential information.

  • Streamlined Workflow:
  • -The solution eliminates the need for direct attachment sharing through emails, simplifying the process and reducing the potential for errors.

  • Centralized Management:
  • -SharePoint Portal Server serves as a centralized repository for sensitive attachments, providing centralized management and control.

  • Auditability:
  • -Comprehensive tracking and auditing capabilities provide visibility into all attachment transfers, enhancing compliance and accountability.
