Assuming f<n/3, this is regardless of the failure detector output. A zero-degrading protocol reaches consensus in two communication steps in every stable run, i.e., when the failure detector makes no mistakes and its output does not change. We show that no leader-based consensus protocol can be simultaneously one-step and zero-degrading. We propose two approaches to circumvent the impossibility result and present corresponding consensus protocols. Further, we present an atomic broadcast protocol that has a latency of 3delta in every stable run and a latency of 2delta in case of no collisions. Finally, we evaluate its performance in a cluster of workstations","PeriodicalId":228470,"journal":{"name":"International Conference on Dependable Systems and Networks (DSN'06)","volume":"46 16","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131589139","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}

Thus, attackers constructing and maintaining botnets are forced to find ways to avoid honeypot traps. In this paper, we present a hardware and software independent honeypot detection methodology based on the following assumption: security professionals deploying honeypots have liability constraints such that they cannot allow their honeypots to participate in real (or too many real) attacks. Based on this assumption, attackers can detect honeypots in their botnet by checking whether the compromised machines in the botnet can successfully send out unmodified malicious traffic to attackers' sensors or whether the bot controller in their botnet can successfully relay potential attack commands. In addition, we present a novel \"two-stage reconnaissance\" worm that can automatically construct a peer-to-peer structured botnet and detect and remove infected honeypots during its propagation stage. Finally, we discuss some guidelines for defending against the general honeypot-aware attacks","PeriodicalId":228470,"journal":{"name":"International Conference on Dependable Systems and Networks (DSN'06)","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128791212","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}

Application QoS requirements are defined by complementary specifications for acceptable and time-limited degraded performance. Furthermore, a requirement specification is provided for both the normal case and for the case where an application server fails in the pool. Independently, the resource pool operator provides a resource access QoS commitment for two classes of service (CoS). These govern statistical multiplexing within the pool. A QoS translation automatically maps application demands onto the resource pool's CoS to best enable sharing. A workload placement service consolidates applications to a small number of servers while satisfying application QoS requirements. The service reports whether a spare server is needed or how applications affected by a single failure can operate according to failure QoS constraints using remaining servers until the failure can be repaired. A case study demonstrates the approach","PeriodicalId":228470,"journal":{"name":"International Conference on Dependable Systems and Networks (DSN'06)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114883842","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}

A model based on these distributions is then formulated, and is solved exactly using the method of spectral expansion.

However, the participant nodes are highly dynamic and unreliable. Thus, any shared resource such as file objects must incorporate redundancy to be useful. While many studies have proposed heuristics to determine redundancy levels based on object popularity, there has been little work in determining optimal or near-optimal resource allocation based on node reliability. In this paper, we present a strategy for the allocation of objects in the presence of dynamic and unreliable peers. We have built an availability model of peer-to-peer storage systems based on the bimodal and time-dependent availability characteristics of a P2P node. Using this model, we can select the size of a candidate node set for storage allocation and assign storage objects to maximize availability while still maintaining a balanced distribution of objects","PeriodicalId":228470,"journal":{"name":"International Conference on Dependable Systems and Networks (DSN'06)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132492372","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}

Techniques for the detection and mitigation of Internet threats using content prevalence and scan detectors are based on assumptions of how threats propagate. Some of these assumptions have recently been called into question by observations of huge discrepancies in the quantity of specific threats detected at different points around the Internet. We call these deviations from uniform propagation \"hotspots\". This paper quantifies and explains these influences on malware propagation. We then propose that hotspots can be explained by two fundamental influences on propagation: algorithmic factors and environmental factors. We use measurement data from sensors deployed at 11 locations around the Internet to demonstrate the impact of these factors on worm and bot propagation. With this understanding, we simulate the outbreak of new threats with hotspots and show how algorithmic and environmental factors reduce the visibility of distributed detectors resulting in the inability to identify new threats","PeriodicalId":228470,"journal":{"name":"International Conference on Dependable Systems and Networks (DSN'06)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123983472","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 computational cost of such CRCs can be too high for resource-constrained embedded systems, which are predominantly equipped with 8-bit microcontrollers that have limited computing power and small memory size. We evaluate the options for speeding up CRC computations on 8-bit processors, including comparing variants of table lookup approaches for memory cost and speed. We also evaluate classes of CRC generator polynomials which have the same computational cost as 24- or 16-bit CRCs, but provide 32-bit CRC levels of error detection, and recommend good polynomials within those classes for data word lengths typical of embedded networking applications","PeriodicalId":228470,"journal":{"name":"International Conference on Dependable Systems and Networks (DSN'06)","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115742170","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 popularity arises out of the simplistic appeal, ease of use, and independence from attack-specific properties such as scanning strategies and signatures. However, such approaches have known limitations: they either fail to detect low-rate attacks or incur very high false positive rates. We propose a multi-resolution approach to enhance the power of threshold-based detection and rate-limiting techniques. Using such an approach we can not only detect fast attacks with low latency, but also discover low-rate attacks - several orders of magnitude less aggressive than today's fast propagating attacks -with low false positive rates. We also outline a multi-resolution rate limiting mechanism for throttling the number of new connections a host can make, to contain the spread of worms.

Yet only a few studies have analyzed and coped with the effects of corrupted sensor data. This paper contributes with the proposal of an on-the-fly statistical technique that can detect and distinguish faulty data from malicious data in a distributed sensor network. Detecting faults and attacks is essential to ensure the correct semantic of the network, while distinguishing faults from attacks is necessary to initiate a correct recovery action. The approach uses hidden Markov models (HMMs) to capture the error/attack-free dynamics of the environment and the dynamics of error/attack data. It then performs a structural analysis of these HMMs to determine the type of error/attack affecting sensor observations.
