Shubha Mishra, R. K. Pateriya . Mitigating DDoS using Threshold-based Filtering in Collaboration with Capability Mechanisms. International Journal of Computer Applications. 96, 10 ( June 2014), 49-54. DOI=10.5120/16833-6597
Capability based approaches have been a major area of work since long time. They are robust against address spoofing attacks. However, they are vulnerable to a new type of attack called Denial-of-Capability attack. Also, bandwidth flooding is another serious issue. This article proposed a novel approach for collaboration of capability with a filtering mechanism. Dynamic threshold for traffic monitoring, implemented over underlying basic capability approach is an effective attempt to mitigate these two major vulnerabilities. A detailed framework is discussed in this research work along with estimation of the expected latency. Essential algorithms are provided for implementation of the approach. The approach is an effective key to handle loopholes in capability techniques. Since, no standalone solution exists for DDoS mitigation; this work provides a collaborative defense, thereby, enhancing robustness against them.
