4. Access Control
Access control, in the realm of information security, governs who can view, modify, or distribute data. When combined with encryption mechanisms that prevent email forwarding, even with granted permissions, it establishes a potent barrier against unauthorized dissemination of sensitive content. This integration ensures that only the intended recipient can access the information, regardless of any other assigned access rights. The following explores specific facets of this combined approach.
-
Principle of Least Privilege Enforcement
The principle of least privilege dictates that users should only have the minimum necessary access to perform their job duties. Encrypted email that cannot be forwarded is a direct application of this principle. By restricting the ability to forward an email, even if a recipient possesses broad permissions within a system, access to the content is confined solely to the intended party. For example, a contractor receiving confidential project specifications can view the documents but cannot forward them to unauthorized personnel, adhering to the contractor’s limited access privilege.
-
Role-Based Access Control (RBAC) Augmentation
RBAC assigns access rights based on defined roles within an organization. However, RBAC alone may not prevent an authorized user from intentionally or unintentionally sharing sensitive information beyond their immediate role. When paired with encryption and forwarding restrictions, RBAC is augmented by technical controls. For instance, a manager might have permission to view employee performance reviews but cannot forward those reviews to individuals outside of human resources, further securing confidential employee data.
-
Breach Containment Enhancement
In the event of a security breach, limiting the spread of compromised information is crucial. Encrypted email with forwarding restrictions serves as a containment mechanism. Even if an attacker gains access to an authorized user’s account, the inability to forward encrypted emails prevents the attacker from rapidly disseminating sensitive data to a wider audience. For example, if a marketing employee’s account is compromised, the attacker cannot easily forward a list of customer email addresses to an external spam vendor due to the imposed restrictions.
