Agents should be enhanced with tools and mechanisms in order to autonomously achieve this strategic and ambitious objective. In this paper, we focus on what we consider the central issue when moving towards the vision of semantic multi-agent systems: the ontology support. Due to the heterogeneity of resources available and roles played by different agents of a system, a one-level approach with the aim of being omni-comprehensive seems not to be feasible. In our opinion, a good compromise is represented by a two-level approach: a light ontology support embedded in each agent and one or more ontology servers providing a more expressive and powerful ontology support to the agents of the systems.","PeriodicalId":128074,"journal":{"name":"14th IEEE International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprise (WETICE'05)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125090969","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}

At that time the focus was on collaboration services providing functionalities at middleware level which could be reusable at the application level. Reflecting this focus, the Research European Union 6th Framework Programme Strategic Objective 2.5.9 \"Collaborative working environments\" was drafted up to achieve a common repository of collaboration services to be invoked by collaboration tools and integrated into large validating applicators. A budget of 40 Mio € is devoted to this Strategic Objective (SO) in 2005. Work to be carried out within this SO will contribute to the use of collaborative technologies with a mediating role among distributed workers and as a glue of diverse technologies (such as mixed-reality, visualisation, interfaces technologies) to support collaboration among people and other artefacts (robots, actuators, sensors).","PeriodicalId":128074,"journal":{"name":"14th IEEE International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprise (WETICE'05)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122190313","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}

Our method attributes several behavioural properties to individual hosts like ratio of outgoing to incoming traffic, responsiveness and number of connections. These properties are used to group hosts into distinct behaviour classes. We use flow-level (Cisco Net Flow) information exported by the border routers of a Swiss Internet backbone provider (AS559/SWITCH). By tracking the cardinality of each class over time and alarming on fast increases and other significant changes, we can early and reliably detect worm outbreaks. We successfully validated our method with archived flow-level traces of recent major Internet e-mail based worms such as MyDoomA and Sobig.F, and fast spreading network worms like Witty and Blaster. Our method is generic in the sense that it does not require any previous knowledge about the exploits and scanning method used by the worms. It can give a set of suspicious hosts in near real-time that have recently and drastically changed their network behaviour and hence are highly likely to be infected.","PeriodicalId":128074,"journal":{"name":"14th IEEE International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprise (WETICE'05)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115014293","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}

Anomaly detection is at present time often implemented to some extent in available intrusion detection products. Still much effort is spent on anomaly detection research and many problems remains to be explored. Performing anomaly detection in real-time places hard requirements on the algorithms used. First, to deal with the massive data volumes one needs to have efficient data structures and indexing mechanisms. Secondly, the dynamic nature of today's information networks makes the characterization of normal requests and services difficult. What is considered as normal during some time interval may be classified as abnormal in a new context, and vice versa. These factors make many proposed data mining techniques less suitable for real-time intrusion detection. ADWICE (anomaly detection with fast incremental clustering) uses incremental clustering and an integrated grid-based index to implement fast, scalable and adaptive anomaly detection.","PeriodicalId":128074,"journal":{"name":"14th IEEE International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprise (WETICE'05)","volume":"158 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133005568","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}
