Abstract:This paper first describes the developments in data and applications security with a special emphasis on database security. It also discusses current work including security for data warehouses and e-commerce systems. Then it discuses some of the directions for data and applications security which includes secure semantic web, secure dependable information management, and secure sensor information management. Directions for privacy research are also given.

“…More recently, Dali [17], RTSORAC [51], and RTDM (Real-time Data Manager) [5] have been developed as mainmemory object-oriented database systems. Like MDARTS, they all maintain databases in shared memory and don't use a client-server architecture in order to provide high performance required in real-time systems.…”

“…Of the prior real-time database prototypes or simulations reported in [2], [5], [7], [14], [21], [23], [36], [40], [47], [51], none provides hard real-time guarantees and none has average transaction times of database systems that are suitable for high-speed hard real-time systems such as machine tool controllers. Because suitable database management systems have been unavailable, hard real-time systems have traditionally used ad hoc methods for data management.…”

ÐComplex real-time systems need databases to support concurrent data access and provide well-defined interfaces between software modules. However, conventional database systems and prior real-time database systems do not provide the performance or predictability needed by high-speed, hard real-time applications. To address this need, we have designed, implemented, and evaluated an object-oriented database system called MDARTS (Multiprocessor Database Architecture for Real-Time Systems). MDARTS avoids the client-server overhead of most prior real-time database systems and object-oriented, real-time systems by moving transaction execution into application tasks. By eliminating these sources of overhead and focusing on basic data management services for control systems (data sharing, serializable transactions, and multiprocessor support), our MDARTS prototype provides hard real-time transaction times approximately three orders of magnitude faster than prior real-time database systems. MDARTS ensures bounded locking delay by disabling preemption when a transaction is waiting for a lock and, hence, allows for the estimation of worst-case transaction execution times. Another contribution of MDARTS is that it supports explicit declarations of real-time requirements and semantic constraints within application code. The MDARTS library examines these declarations at application initialization time and attempts to construct objects that are compatible with the requirements. Besides local sharedmemory transactions with hard real-time response time guarantees, MDARTS also supports remote transactions that use remote procedure calls for data access with less stringent timing constraints. Our MDARTS prototype is implemented in C++ and it runs on VME-based multiprocessors and Sun workstations.

MITRE's Evolvable Real-Time C3 (Command, Control, and Communications) project has developed an approach that would enable current real-time systems to evolve into the systems of the future. This paper first summarizes the design and implementation of an infrastructure for an evolvable real-time C3 system. Then, a detailed discussion of the infrastructure requirements for a survivable real-time C3 system is presented. Finally security issues for survivability, as well as open implementation of the infrastructure, are described. In particular, adaptable middleware for survivable systems is discussed.
