Which method assists in mitigating unauthorized use of Transient Cyber Assets?

The method that effectively assists in mitigating unauthorized use of Transient Cyber Assets is full-disk encryption. This technique ensures that all data on the storage devices of these assets is encrypted and thus rendered inaccessible without proper authorization. When transient cyber assets, which may include laptops, USB drives, or other portable devices, are used in the field and potentially exposed to risks such as theft or loss, full-disk encryption secures the data within.

If the asset is lost or stolen, the encryption helps prevent unauthorized individuals from accessing sensitive information or system controls, thus safeguarding the integrity and confidentiality of critical infrastructure. This is particularly relevant for transient assets, as they can easily be carried outside of secure environments, increasing the likelihood of unauthorized access.

While security patch management, application whitelisting, and removing all network connections are important methods for protecting cybersecurity, they do not directly focus on securing transient devices in a scenario where they may be vulnerable due to their portability. Security patch management is about keeping software updated, application whitelisting restricts which applications can be run, and removing network connections can help in certain contexts but does not protect data on the device itself if it is accessible. Hence, full-disk encryption specifically targets the risks associated with unauthorized use of transient
