Unmanned vehicles are ideal for intelligence, surveillance, and reconnaissance (ISR) missions due to the amount of data a vehicle can gather without the risk to human life. As they are increasingly being used to gather large amounts of different types of data, the need for data storage versatility and data security rises. However, the risk of data loss or corruption grows as the number of systems using different protocols connecting to the device rises. Additionally, as the use of unmanned vehicles for deployed applications increases, so does the risk of highly sensitive data being lost or captured in hostile territory. Through disk partitioning and commercial off-the-shelf (COTS) data-at-rest (DAR) encryption, this paper proposes a solution that reduces risk of data loss, corruption, and accessibility if intercepted.
