We present and experimentally evaluate Spread Identity (SI)—a new dynamic network address remapping mechanism that provides anonymity and DDoS defense capabilities for Internet communications. For each session between a source and destination host, the trusted source gateway dynamically and randomly assigns an IP address for the source host from the pool of(More)
Assignment problem in content distribution networks (CDN) is unsplittable hard-capacitated facility location problem (UHCFLP) because of underlying anycast routing protocol. We extend assignment problem in CDN to multidimensional facility location problem (MFLP). With our devised algorithm, assignment cost considers CPU utilization parameter along with(More)
We introduce Markov Model for Web services attacks detection and mitigation. This model is capable of preventing not only injection attacks like SQL injection, Cross-Site Script-ing (XSS), buffer overflow but also detect abnormal Web service client behavior. We adopted the well known technique based on Markov model for detecting Web application attacks. Our(More)
The Internet is rapidly being adopted as the dominant communication medium, as evidenced by the recent explosive growth of companies and services that integrate the traditional telephone service simply as a type of data-service over the Internet (viz., Voice-over-IP). Continuous and ubiquitous availability of Internet services is therefore increasingly(More)
