For calculating risk-based exposure amounts, the subsequent details are given:

In a recent incident, a control center reported a virus infection to the BSI (Federal Office for Information Security) in Germany. The root cause of the infection was traced back to a USB drive, which had been used in other control centers before.

Before the appointment at the control center, the service technician had connected the USB drive to his private PC. This action, coupled with the lack of protective mechanisms installed on systems in control centers, allowed the malware to infiltrate the system.

The antivirus software raised an alarm when the USB drive was used, but the operator, unaware of the threat, proceeded with the drive. Uninfected data can remain on the storage device, be copied to a provided alternative storage device, or be copied via Secure File Transfer to the MetaDefender Vault. However, the malware had already done its damage.

To prevent such incidents in the future, the BSI recommends not using USB drives for software updates in control centers. Instead, they suggest implementing Data Loss Prevention or Device Control in these critical environments.

One solution proposed is the use of the OPSWAT MetaDefender Kiosk for removable media lock. This system, featuring at least 8 anti-virus engines, can inspect mobile storage devices, similar to airport security checks. The BSI also recommends the use of Multiscanning using an Anti-Malware Multiscanner for the removable media lock.

Furthermore, the BSI advises the use of the MetaDefender Vault for secure data storage. This service allows for the retrieval of data without risk, using a password.

In addition to technical solutions, the BSI also suggests guidelines for professional and private use of IT components, including external service providers. Further employee training on IT component usage is also recommended.

The BSI case study on this incident provides valuable insights into the importance of securing control centers and the potential risks posed by USB drives. It is strongly advised to read this case study or learn more about the topic of removable media lock.

In conclusion, the USB drive incident serves as a reminder of the need for vigilance and the implementation of robust security measures in control centers. By following the recommended guidelines and solutions, the risk of similar incidents can be significantly reduced.
