Most solutions that have been proposed to counter this threat are based on our ability to quickly detect the malware-generated traffic or the malware instances themselves, something that in many cases can be beyond our ability. Nonetheless, it seems intuitive that certain defensive postures adopted in configuring networks or machines can have a positive impact on countering malware, regardless of our ability to detect it. It is thus important to quantitatively understand how changes in design and deployment strategies can affect malware performance; only then does it become possible to make optimal decisions. To that purpose, we study in this paper the impact of network interconnection topologies on the propagation of malware. We first use a theoretical model based on Markov processes to try to predict the progression of an infection under varying interconnection scenarios. We then compare these predictions with experimental results obtained by launching a malware emulation agent on three differently configured networks. Both theoretical and experimental results provide quantitative confirmation of the intuition that networks with higher degrees of interconnection allow faster spread of malware. In addition to this, we believe that the models, experimental methodology and tools described here can be safely and fruitfully used to study other aspects of malware performance, and hence of the relative effectiveness of defensive counter-measures.","PeriodicalId":356565,"journal":{"name":"2007 IEEE International Performance, Computing, and Communications Conference","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124211251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper we have considered two important abases in electronic payments systems for detection. The fraud, which is an intentional deception accomplished to secure an unfair gain, and an intrusion which are any set of actions that attempt to compromise the integrity, confidentiality or availability of a resource. Most of the available fraud and intrusion detection systems for e-payments are specific to the systems where they have been incorporated. This paper proposes a generic model called as activity-event-symptoms (AES) model for detecting fraud and intrusion attacks which appears daring payment process in the mobile commerce environment. The AES model is designed to identify the symptoms of fraud and intrusions by observing various events/transactions occurs daring mobile commerce activity. The symptoms identification is followed by computing the suspicion factors for event attributes, and the certainty factor for a fraud and intrusion is generated using these suspicion factors. We have tested the proposed system by conducting various case studies, on the in-house established mobile commerce environment over wired and wire-less networks test bed.","PeriodicalId":356565,"journal":{"name":"2007 IEEE International Performance, Computing, and Communications Conference","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133987792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These applications utilize the UDP protocol because TCP is not suitable for streaming applications since its congestion control mechanism can change the connection's transmission rate drastically, affecting the user-perceived quality of the transmission. Nonetheless, the use of end-to-end flow and congestion control mechanisms for streaming applications has been acknowledged as an important measure to ease or eliminate the congestion collapse problem in the Internet, and the unfairness problem that exist when TCP and UDP share the same congested bottleneck link. In this paper, we propose the smooth fair TCP SACK-based (SF-SACK) protocol to address these problems. SF-SACK implements the well-known end-to-end window-based congestion control algorithm of TCP but uses an additive increase smooth decrease (AISD) strategy that considers history in the evolution of the congestion window. Through simulations and experimentation, we show that if SF-SACK is used by both streaming and data-oriented applications, streaming applications receive a smooth service, and fairness is achieved. If SF-SACK is used for streaming applications only, it is unfair to TCP (not TCP-friendly) but substantially fairer and beneficial than UDP.","PeriodicalId":356565,"journal":{"name":"2007 IEEE International Performance, Computing, and Communications Conference","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127859500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
