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:

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

  • Attachment Detachment:

 

-For identified sensitive attachments, the solution intercepts the email messages and detaches the attachments from the original emails.

 

  • Attachment Upload to SharePoint:

 

-The detached sensitive attachments are securely uploaded to a designated SharePoint Portal Server location.

 

  • Attachment Delivery:

 

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

 

  • Secure Access:

 

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

 

  • User Authentication:

 

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

 

  • Access Restrictions:

 

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

 

  • Tracking and Auditing:

 

-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.
