This booklet constitutes the refereed complaints of the ninth foreign Workshop on safety, IWSEC 2014, held in Hirosaki, Japan, in August 2014. The thirteen normal papers awarded including eight brief papers during this quantity have been conscientiously reviewed and chosen from fifty five submissions. the point of interest of the workshop was once at the following themes: procedure safety, threshold cryptography, safety, origin, and encryption.

Example text

The process information of the essential service is replaced without disturbing its functionality. Adversaries cannot detect and identify a target for attack because the process information of the target is replaced. For security and adaptability, the proposed method is implemented using a VMM. Because of its design, a VMM is more difficult to attack than an operating system (OS). Furthermore, implementation with modification to a VMM can reduce the costs involved in modifying existing software.

Consider as an example a process unit that produces ammonia in which a pressure in a vessel is maintained with a pump. Maintaining the right ammonia pressure is critical to the financial health of the plant. Another pump is responsible for the outflow of the ammonia from the vessel but is not considered critical to the economy of the plant. It may be possible to set up a standing wave between the two pumps that has a direct impact on the ability of the first pump to perform its function. In that case the state of the non-critical pump can be considered hidden impact data for the CPS that contains the critical pump.

The valve on the other hand is seen as a single element in a larger subcomponent of a factory. The scope of a CPS depends greatly on the definition of the “system”. The choices made in designing a communications architecture can quickly add a large number of devices to a CPS, as a common infrastructure is used in the control of individual systems. A properly defined CPS should include all of the devices that can be used to manipulate it. Under this definition an attacker must interact with some part of the CPS to achieve her goals.
