The need for software component survivability is pressing for mission-critical systems in information warfare. In this chapter, we describe how mission-critical distributed systems can survive component failures or compromises with malicious codes in information warfare. We define our definition of survivability, discuss the survivability challenges in a large mission-critical system in informa...

ISSUE ADDRESSED People's decisions about whether to participate in cancer screening and to seek treatment are related to their perceptions of the survivability of cancer. However, there is little empirical evidence to suggest people's awareness of the survivability of different cancers. The object of the present study was to determine people's estimates of the survivability of 10 cancers. MET...

Survivability engineering is critical for minimizing the impact of disturbances to the operation of space systems. To improve the evaluation of survivability during conceptual design, metrics are proposed for the assessment of survivability as a dynamic, continuous, and path-dependent system property. Two of these metrics, time-weighted average utility loss and threshold availability, are then ...

The Call for Participation of ISW-2000 defines information survivability as “the ability of a system to continue to fulfill its mission in the presence of attacks, accidents, or failures”. This position paper presents two concepts: the design diversity technique [1, 2] and the immune system paradigm [3] that already have been found to be useful in assuring the dependability of mission-critical ...

Time-varying graphs are a useful model for networks with dynamic connectivity such as mmWave networks and vehicular networks, yet, despite their great modeling power, many important features of time-varying graphs are still poorly understood. In this thesis, we study the survivability properties of time-varying networks against unpredictable interruptions. We first show that the traditional def...

A Survivability Research Agenda Survivability is the capability of an information system to support critical enterprise missions in adverse environments of attacks, failures, and accidents [Ellison et al 1999]. A research program in survivability must therefore address both systems and the environments within which they operate. Survivability is a combination of quality attributes, including se...

The contribution of this paper is to present the network modeling methodology to make it possible to test the survivability of computer network. As the structure and behavior of network becomes complicated and unpredictable, it becomes difficult to test the survivability of computer network. The modeling and simulation is a widely used approach to Predict the behavior of system or set of system...

The survivability of critical infrastructure systems has been gaining increasing concern from the industry. The survivability research area addresses the issue of infrastructure systems that continues to provide pre− established service levels to users in the face of disorders and react to changes in the surrounding environment. Workflow management systems need to be survivable since they are u...
