  • Organizational Risk Assessment Based on Attacks Repetition

    Availability, Reliability and Security (ARES), 2012 Seventh International Conference

    Risk assessment is a very critical and important process to protect the organization assets and reputation against security threats and risks. It provides a clear picture of the current threats that the organization is facing and helps the top management to take the right decision to eliminate or mitigate those risks. Usually if the vulnerability is exploited, the same attack may be happen twice or more in a different time periods because the vulnerability has been exploited and not mitigated…

    Risk assessment is a very critical and important process to protect the organization assets and reputation against security threats and risks. It provides a clear picture of the current threats that the organization is facing and helps the top management to take the right decision to eliminate or mitigate those risks. Usually if the vulnerability is exploited, the same attack may be happen twice or more in a different time periods because the vulnerability has been exploited and not mitigated. In this paper, we are illustrating our observation of the relation between the risk value and the number of attacks targeting this risk.

  • Cooperation incentives in wireless Ad hoc networks

    Education Technology and Computer (ICETC), 2010 2nd International Conference

    Mobile ad hoc networks heavily rely on nodes' cooperation for packet forwarding. As a result, misbehaving, malicious, and selfish nodes can significantly degrade the performance of the network. To cope with this issue and to stimulate cooperation among selfish mobile nodes, a continuous research effort is done on identifying nodes trust and reputation. In this paper, we survey recently proposed reputation and incentive schemes for ad hoc networks. In order to help in the design of different…

    Mobile ad hoc networks heavily rely on nodes' cooperation for packet forwarding. As a result, misbehaving, malicious, and selfish nodes can significantly degrade the performance of the network. To cope with this issue and to stimulate cooperation among selfish mobile nodes, a continuous research effort is done on identifying nodes trust and reputation. In this paper, we survey recently proposed reputation and incentive schemes for ad hoc networks. In order to help in the design of different reputation systems tailored to specific applications and network topologies, we classify the different approaches that have been used in the literature and present the different alternatives for each approach. Finally, we conclude this paper and present suggestions for future work.
