Abstract:
The present disclosure pertains to systems and methods of restricting access to devices utilizing tokens. In some embodiments, a system may include a user requesting a token, ensuring the user requesting a token has the permission to request the token and is not the user approving the token. In some embodiments, the system may include the user granting the token, wherein the user granting the token is not the user receiving the token. The system ensures that the user accessing the device has the permission to access the device. Additionally, the system decreases the opportunities for insider attacks and increases the resistance to credential theft attacks. Further, the system increases the accountability for changes and the ability to review changes.
