Aidan McGraw's requirements to protect sensitive information shared outside the organization can be satisfied by Information Rights Management (IRM).
IRM Overview: IRM is a form of IT security technology used to protect documents containing sensitive information from unauthorized access. It does this by encrypting the data and embedding user permissions directly into the file1.
Encryption and Permissions: IRM allows for the encryption of the actual data within the file and includes access permissions that dictate who can view, edit, print, forward, or take other actions with the data. These permissions are enforced regardless of where the file is located, making it ideal for sharing outside the organization1.
Protection Against Attacks: By using IRM, Aidan ensures that even if attackers were to gain access to the file, they would not be able to decrypt the information without the appropriate permissions. This protects against unauthorized intruders and hackers1.
