We implemented a environment to test SMTP server performance focusing on denial of service (DoS) attacks. Our measurements show that a standard SMTP server can be easily overloaded by sending simple email messages and the overload can occur without consuming all network bandwidth. Our measurements also show that the usage of content filtering applications can harm the performance so much that the server become even more vulnerable to DoS attacks. In the paper we describe the problems of performance measurements in SMTP environment and we also give a detailed background about the performed measurements.","PeriodicalId":363805,"journal":{"name":"2007 International Symposium on Collaborative Technologies and Systems","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120944139","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}

This chaotic behavior manifests both when humans are acting alone and when they are interacting with semi-autonomous devices in real and simulated environments. Other studies have reported that robots alone also exhibit mathematically chaotic behavior. This has led to the working hypothesis that chaotic measures such as the Lyapunov exponent can be used to quantify performance levels in human robot collaboration in an objective way. Experiments are in progress to help better understand and quantify the occurrence of chaotic behavior in human robot collaboration. The expectation is that Lyapunov exponent and other chaos-related measures will prove useful as diagnostic tools for both operational tasks and for training. Our goal is to investigate using overt actions (navigational inputs now and possibly other things like facial expression in the future) for capturing the Lyapunov exponent in real time and as a function that varies over time in response to behaviors. The challenge is to determine which factor to measure for a specific type of task. Additional research will be needed to link task to human psychophysical activity and to robot activity as well as the ability to transition between data modes as tasks change.","PeriodicalId":363805,"journal":{"name":"2007 International Symposium on Collaborative Technologies and Systems","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123848099","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}

This environment is designed to function across multiple platforms, bringing the display of visual information and the capture of reasoning associated with that information to both mobile and desktop clients. The service-oriented architecture of SRS facilitates collaboration and interaction between users regardless of their location or platform. Visualization services allow data processing to be centralized and analysis results to be collected from distributed clients in real time. We use the concept of ldquoreasoning artifactsrdquo to capture the analytic value attached to individual pieces of information and collections thereof, helping to fuse the foraging and sense-making loops in information analysis. Reasoning structures composed of these artifacts can be shared across platforms while maintaining references to the analytic activity (such as interactive visualization) that produced them.","PeriodicalId":363805,"journal":{"name":"2007 International Symposium on Collaborative Technologies and Systems","volume":"92 1-3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128159871","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}
