Most of them rely on sensors dedicated to local area networks or Internet. However clusters rely heavily on networks. Because of their uniformity, they are sensible to attacks: one compromised node can lead to the control of whole cluster. In order to solve such security issues, we purpose a NIDS architecture which addresses the same constraints as a cluster: efficiency, scalability and reliability. It is based on the cluster paradigm. We stress on the facts that network packets must be dispatched according to streams and analysis must be load-balanced at process level. Moreover two types of practical parallel analysis are presented, depending on the type of flows. Finally, we discuss implementations and dimensioning issues","PeriodicalId":283620,"journal":{"name":"Proceedings of the 2005 International Symposium on Collaborative Technologies and Systems, 2005.","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123824705","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}

Participants in the study included computer science students from the University of North Texas (UNT) in Denton, Texas and students from the Middle East Technical University (METU) in Ankara, Turkey. Students were divided into culturally diverse work-teams and assigned collaborative software development projects. Cultural distinctions between work-teams were based upon the students' responses to the cultural perspectives questionnaire (CPQ) developed by Maznevski, et al. Completed projects were evaluated with respect to several criteria, such as whether objectives were met, design efficiency and documentation completeness. Results from the study indicate that a work-team's cultural composition is a predictor of a work-team's performance. These and other questions are being addressed in our next round of studies","PeriodicalId":283620,"journal":{"name":"Proceedings of the 2005 International Symposium on Collaborative Technologies and Systems, 2005.","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132681618","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}

Instant messaging systems utilize awareness in communication and are commonly used to coordinate workplace collaborations. We describe a context-aware instant messaging prototype that aims to reduce unsuccessful communication attempts by updating the availability of the users automatically. The system utilizes the contexts of both the communication initiator and receiver to infer the availability of the receiver. We strive to identify the needs for, and further requirements of such systems by analyzing the results of a week-long user test period, conducted in an everyday working environment. The users generally find automatic availability updating with awareness information to improve the value of instant messaging in collaborative work.

Subsequently, hiding identities and respecting citizens' privacy are becoming extremely important. Dedicated to this issue, this paper is organized as follows: after defining the topic through an example of collaborative complex and heterogeneous system, this paper analyzes the most typical anonymization procedures. Afterwards it proposes a rigorous approach to define anonymization requirements, as well as how to characterize, select and build solutions. Finally, a new generic procedure to anonymize and link identities is proposed. We suggest that a critical part of this procedure is carried out in a smart card. According to needs, anonymized data are processed through cryptographic transformations in several organizations. Our solution is suitable to collaborative environments; guarantees the user's consent; resists dictionary attacks; respects the least privilege principle and thus fulfils the legislation requirements. Moreover, it remains flexible, adaptable to different fields, and supports some organizational changes like the merging of several systems","PeriodicalId":283620,"journal":{"name":"Proceedings of the 2005 International Symposium on Collaborative Technologies and Systems, 2005.","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121704690","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}
