Enterprise Safety Information Systems QR Code Security Findings

I coordinated security mitigation for using a mobile device to collect data in the field and information aggregation capabilities.

It was recommended to use a QR code to gain access to the system. If using a user-specific QR Code and logging off the mobile application, you will need to go back into the SIMS solution and get another QR code.

This means that if a user logs into the mobile application with a user-specific QR code and logs out when out in the field, they will be unable to access the application until they get a new QR Code. The user would have to log into the SIMS solution via VPN on a company device to get another QR code. There is no “time out” in the mobile application, so users stay logged in until they manually log out.

If a mobile device is stolen, the user would have to immediately contact the IT corporate support desk to disable their access because they could still be logged into the mobile application.

Due to the risk and proposed mitigation, the stakeholder decided not to release the mobile version until these issues were fixed.
I recommend leveraging their Microsoft Azure to authenticate and access applications when the user is off the network.
