Survivability Architectures
Abstract
Many large information systems have evolved to a point where organizations rely heavily upon them. In some cases, such systems are so widespread and so important that the normal activities of society depend upon their continued operations. Management of transportation systems such as air traffic control, telecommunications, nationwide control of power distribution, and the financial system are examples. Military information systems are similar in that many military functions are dependent on large information systems, and the ability of the Department of Defense to use its resources effectively is contingent on the proper operation of these information systems. Such systems, both civilian and military, are referred to as critical information systems. Improving the survivability of critical information systems is essential for both civilian and military applications. The way in which this is done is to implement a monitoring and control structure known as a survivability mechanism that operates separately from the information system itself. The survivability mechanism is responsible for detecting faults and recovering from them. Important issues that arise from this approach are fast and flexible reconfiguration of the application when faults occur and protection of the survivability mechanism against security attacks.
