“…Despite the best efforts of security researchers, no amount of hardening can assure that a system that is connected to an unbounded network will be invulnerable to attack. The survivability can help ensure that such systems can deliver essential services and maintain essential properties such as integrity, confidentiality, and performance, despite the presence of intrusions [1][2]- [3] [4].…”

Traditional security approaches are not sufficient to deal with the protection and survivability of highly distributed information systems operating in unbounded networks. In view of the deficiencies of the essential services' self-recovering when the survivable system is not available, an efficient self-adjusting reconfiguration framework on system survivability is presented based on the service-level QoS. In this framework, some QoS metrics are discussed, and the survivability reconfiguration trigger condition is made, then the application steps of survivability reconfigureation are described in detail, and corresponding dynamic reconfiguration algorithm is given. The framework can probe the newest state of system, give the decision guideline quantificationally, and execute the dynamic reconfiguration algorithm in bounded time when system suffers attack or failure, then take some reconfiguration actions correctly.

“…Survivability is calculated as a percentage of remaining network traffic flow to the original traffic after the communication network has been destroyed [9]. The authors of [10] developed a tool to assess survivability by evaluating reliability, availability, and restorability of SONET networks using a Parametric State Reward Markov Model (SRMM/p). In [11] survivability is calculated as network performance where the fraction of time in failure state affects the performance.…”

The GPRS network has been well integrated in Global System for Mobile (GSM) network, the most dominant cellular standard, to accomplish efficient spectrum utilization for data traffic. It has become a popular service which carries critical business and social information of many subscribers. The issue of survivability for a GPRS network requires more investigation. This work introduces a new measure of survivability, Survivability Index (SI), which takes into account following important features of a GPRS network (i) success probability in uplink contention, (ii) average wait time to get a dedicated slots (iii) throughput and (iv) availability. A weighted sum form is proposed and Genetic Algorithm (GA) is used to find optimum values of weights. Considering various failure scenarios the Survivability Index has been evaluated for a GPRS network.

“…Simultaneously, in our country, the research on index system of survivability evaluation is also very few, having no related literatures to report yet, and overseas there exist problems that the description for index is too simple, not standard, and not comprehensive etc. For example, literatures [2-4] discuss performance index mainly from the reliability of actual communication connection for network information system; literatures [5][6] focus on network performance guarantee to analyze; literatures [7][8][9] emphasize on the realization of system task and goal to discuss. But the above researches only carry on classified description for survivable performance index, and have not broke through simplicity and limitation of index system and come into standardization phases yet.The set which is consisted of all indexes is called index system.…”

This paper provides a complete performance index for survivability from the aspects of index content, attack phases and evaluating standard, proposes a framework for performance index which can present the survivability, and formalizes the index system. On the basis of which, abstracts the mathematical model of index system, analyses and validates that the proposed index system has the features of standardization and completeness. This research is significant to quantitative evaluation for information systems survivability.
