Despite being ???exible and robust in their ability to self-organize, these MANETS are distinctly more susceptible to attacks than their wired counterparts. Especially in military settings such as the interconnection of infantrymen or autonomous robots, remote initiation of countermeasures is critical since local administrative personnel may not be available. In this contribution we present an architecture for response initiation that is specifically tailored to the requirements intrinsic to mobile ad hoc networks in these settings. First we introduce IRMEF (Intrusion Response Message Exchange Format) as a means of specifying and parameterizing responses remotely which is an extension of the IDMEF RFC, an experimental yet well-established and recommended IETF draft for formatting event messages. Response initiation messages are dispatched from a central location via a secure, reliable, and robust communication infrastructure based on SNMPv3. An Authenticated Flooding service ensures that messages are delivered to their destination even while the network is under attack. Locally installed responder components are responsible for the application of the response measure. These mechanisms are designed and implemented explicitly with the limitations in mind which are imposed by the MANET operating environment: For example, resource constraints are taken into account by avoiding bandwidth intensive message formats, and the use of an intelligent ???ooding mechanism ensures resiliency under routing attacks.","PeriodicalId":375908,"journal":{"name":"2010 European Conference on Computer Network Defense","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127697187","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}

Repeatedly, information leaks occur over the Internet, and half of the time they are accidental, caused by user negligence, misconfiguration of software, or inadequate understanding of an application’s functionality. This paper presents iLeak, a lightweight, modular system for detecting inadvertent information leaks. Unlike previous solutions, iLeak builds on components already present in modern computers. In particular, we employ system tracing facilities and data indexing services, and combine them in a novel way to detect data leaks. Our design consists of three components: uaudits are responsible for capturing the information that exits the system, while Inspectors use the indexing service to identify if the transmitted data belong to files that contain potentially sensitive information. The Trail Gateway handles the communication and synchronization of uaudits and Inspectors. We implemented iLeak on Mac OS X using DTrace and the Spotlight indexing service. Finally, we show that iLeak is indeed lightweight, since it only incurs 4% overhead on protected applications.","PeriodicalId":375908,"journal":{"name":"2010 European Conference on Computer Network Defense","volume":"8 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132398298","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}

However, the volume and diversity of the collected data makes the extraction of information a challenging task. Additionally, the maintenance of the monitoring infrastructure is another demanding and time-consuming effort. To overcome these problems, we present several visualization techniques that enable users to observe what happens in their unused address space over arbitrary time periods and provide the necessary tools for administrators to monitor their infrastructure. Our approach, which is based on open-source standard technologies, transforms the raw information at the network level and provides a customized and Web-accessible view. In this paper, we present the design, implementation and early experiences of the visualization techniques and tools deployed for the NoAH project, a large-scale honey pot-based infrastructure. Additionally, we provide a traffic analysis of data collected over a six month period of our infrastructure's operation. During the data collection period, we observed that the number of attackers continually increased as did the volume of traffic they generated. Furthermore, interesting patterns for specific types of traffic have been identified, such as the diurnal cycle of the traffic targeting TCP port 445 (Windows Directory Services), the port that receives the largest volume of attack traffic.","PeriodicalId":375908,"journal":{"name":"2010 European Conference on Computer Network Defense","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115523977","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}

HTTPreject: Handling Overload Situations without Losing the Contact to the User HTTPreject:在不失去与用户联系的情况下处理过载情况

At the same time, web applications become more and more complex. Therefore, a spontaneous increase in the number of visitors, e.g., based on news reports or events, easily brings a web server in an overload situation. In contrast to the classical model of distributed denial of service (DDoS) attacks, such a so-called flash effect situation is not triggered by a bulk of bots just aiming at hurting the system but by humans with a high interest in the content of the web site itself. While the bots do not stop their attack until told so by their operator, the user try repeatedly to access the site without knowing that the repeated reloads effectively increase the web server's overload. Classical approaches try to distinguish between real user and harmful requests, which is not applicable in this scenario. Simply restricting the number of connections leads to very technical error messages displayed by the users' client software if at all. Therefore, we propose a mean to efficiently block connection attempts and to keep the user informed at the same time. A small subset of HTTP and TCP is state lessly implemented to display simple busy messages or relevant news updates to the end user with only few resources. In this paper we present the protocol subset used and discuss the compatibility problems on the protocol and client software level. Furthermore, we show the results of performance experiments using a prototype implementation.","PeriodicalId":375908,"journal":{"name":"2010 European Conference on Computer Network Defense","volume":"333 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124696035","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}
