Data management and transaction processing for real-time systems are essential in supporting time-critical applications, and hence they have been investigated over the years. However, there has not been much work in supporting security in real-time database systems, although sensitive information must be safeguarded in real-time systems as well. It is clear that a more rigorous model to capture the characteristics and semantics of transactions and data is necessary to improve the timeliness of the system. In addition, new approaches to supporting both requirements in scheduling and concurrency control that can make trade-offs if necessary, need to be developed and analyzed. In this paper, we address issues real-time database systems should consider for supporting both requirements of timeliness and security, and present an adaptive policy to achieve it
