Traditional security approaches are not sufficient to deal with the protection and survivability of highly distributed information systems operating in unbounded networks. This paper discusses the need for and importance of survivability, defines unbounded network, and examines the characteristics that differentiate survivability from other software quality attributes and nonfunctional properti...

In this paper, we propose a general survivability quantification framework which is applicable to a wide range of system architectures, applications, failure/recovery behaviors, and desired metrics. We show how this framework can be used to derive survivability measures based on different definitions and extend it to other measures not covered by current definitions which can provide helpful in...

In this paper, we model the method in which aircraft survivability equipment suites successfully choose their countermeasures, and experiment with their autonomous decision-making against threats in various electronic warfare settings. We have designed and implemented our simulators to estimate the operational effectiveness of the aircraft survivability equipment suite. We formulate the operati...

Survivability is the capability of a system to fulfill its mission in a timely manner in the presence of failures, attacks and accidents. In this paper, quantitative assessment of survivability of cellular networks is conducted by developing an analytical model using Markov chains. A stochastic reward net model is then developed for the automated generation of CTMC and hence survivability metri...

System survivability is the ability to give service in spite of failures of some of the components. To assure survivability is an important goal when designing a communications network backbone, to ensure that it can resist to failures in the switch sites as well as in the connection lines. Previous work has employed a Greedy Randomized Adaptive Search Procedure (GRASP), based on path algorithm...

Survivability has been one of the active fields in network security recently. In order to evaluate the survivability of networked system effectively, this paper proposes a method of combining grey correlation analysis and improved TOPSIS for quantitative assessment. Firstly, it normalizes indicator matrix according to improved TOPSIS method and determines the positive and negative ideal solutio...

This paper described the proposed protection route mechanism and simulation of protection mechanism model in order to achieve survivability in PON-FTTH. Due to large transport capacity achieved by the network, failures which occur cause huge losses of data and greatly influence upon a large number of users over a wide area. Therefore, the survivability of the whole network has to be examined mo...

Employing survivability techniques developed by Architecture Technology Corporation (ATC) under the DARPA OASIS program, VPNshield implements DoSresistant (or survivable) VPNs that provide continuous, uninterrupted operation of VPN services in spite of access link flooding attacks. In contrast to existing infrastructurebased approaches for detecting and countering these attacks, the VPNshield a...

Modeling the ful llment of global properties like survivability is a challenging problem in unbounded systems such as Grids, peer-to-peer systems, or swarms. This paper proposes Folded Interaction Systems (FIS), an extension of the classic I-Systems framework, to overcome the modeling issues. FIS is applied to a case of survivability assessment in Grids and demonstrates the identi cation of ess...
