Buch. Zustand: Neu. Neuware - Database and Application Security XV provides a forum for original research results, practical experiences, and innovative ideas in database and application security. With the rapid growth of large databases and the application systems that manage them, security issues have become a primary concern in business, industry, government and society. These concerns are compounded by the expanding use of the Internet and wireless communication technologies.This volume covers a wide variety of topics related to security and privacy of information in systems and applications, including: Access control models; Role and constraint-based access control; Distributed systems; Information warfare and intrusion detection; Relational databases; Implementation issues; Multilevel systems; New application areas including XML. Database and Application Security XV contains papers, keynote addresses, and panel discussions from the Fifteenth Annual Working Conference on Database and Application Security, organized by the International Federation for Information Processing (IFIP) Working Group 11.3 and held July 15-18, 2001 in Niagara on the Lake, Ontario, Canada.…

Buch. Zustand: Neu. Neuware - With the rapid growth of networking and high-computing power, the demand for large-scale and complex software systems has increased dramatically. Many of the software systems support or supplant human control of safety-critical systems such as flight control systems, space shuttle control systems, aircraft avionics control systems, robotics, patient monitoring systems, nuclear power plant control systems, and so on. Failure of safety-critical systems could result in great disasters and loss of human life. Therefore, software used for safety critical systems should preserve high assurance properties. In order to comply with high assurance properties, a safety-critical system often shares resources between multiple concurrently active computing agents and must meet rigid real-time constraints. However, concurrency and timing constraints make the development of a safety-critical system much more error prone and arduous. The correctness of software systems nowadays depends mainly on the work of testing and debugging. Testing and debugging involve the process of de tecting, locating, analyzing, isolating, and correcting suspected faults using the runtime information of a system. However, testing and debugging are not sufficient to prove the correctness of a safety-critical system. In contrast, static analysis is supported by formalisms to specify the system precisely. Formal verification methods are then applied to prove the logical correctness of the system with respect to the specification. Formal verifica tion gives us greater confidence that safety-critical systems meet the desired assurance properties in order to avoid disastrous consequences. …
