Specifically we demonstrate an implementation of this scheme integrated with an existing MTD implemented in the IPv6 space: the Moving Target IPv6 Defense (MT6D). We show how MT6D peers can use this protocol to exchange configuration information, allowing them to locate other nodes as they move around the Internet, and how they can securely establish connections and related association parameters with no prior knowledge of the other party's network state. We require a minimal amount of pre-shared information between nodes; only that peers have access to public key information. This scheme enables mobility for peers within the MT6D protocol, allows dynamically changing configurations, and allows an MT6D server to scale to supporting many clients without a quadratic explosion in the number of secret keys which need to be maintained.","PeriodicalId":20578,"journal":{"name":"Proceedings of the Second ACM Workshop on Moving Target Defense","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86839684","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}

We develop an automated approach to defending a network against continuous attacks from intruders, using the notion of Bayesian attack graphs to describe how attackers combine and exploit system vulnerabilities in order to gain access and progress through a network. We assume that the attacker follows a probabilistic spreading process on the attack graph and that the defender can only partially observe the attacker's capabilities at any given time. This leads to the formulation of the defender's problem as a partially observable Markov decision process (POMDP). We define and compute optimal defender countermeasure policies, which describe the optimal countermeasure action to deploy given the current information.","PeriodicalId":20578,"journal":{"name":"Proceedings of the Second ACM Workshop on Moving Target Defense","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77243728","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}

Many academic works have created MTDs in different deployment environments. However, network-based MTDs (NMTDs) share key components and properties that determine their effectiveness. In this work, we identify and define seven properties common to NMTDs which are key to ensuring the effectiveness of the approach. We then evaluate four NMTD systems using these properties and found two or more key concerns for each of the systems. This analysis shows that these properties may help guide developers of new NMTD systems by guiding the evaluation of these systems and can be used by others as a rubric to assess the strengths and limitations of each NMTD approach.","PeriodicalId":20578,"journal":{"name":"Proceedings of the Second ACM Workshop on Moving Target Defense","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87339185","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 year's MTD workshop continues its tradition of being the premier forum for presentation of research results and experience reports on leading edge issues of access control, nincluding models, systems, applications, and theory. The mission of the symposium is to share novel access control solutions that fulfill the needs of heterogeneous applications and environments and identify new directions for future research and development. ACRONYM gives researchers and practitioners a unique opportunity to share their perspectives with others interested in the various aspects of access control. \u0000 \u0000The call for papers attracted submissions from Asia, Europe, and United States. Submissions are from both industry and academia. The workshop received 19 submissions. Each submitted paper has at least 3 review comments from TPC members. The program committee reviewed and accepted the following: \u0000Full Technical Papers submitted 19, accepted 8 \u0000Short Experience Reports submitted 19, accepted 4 \u0000 \u0000 \u0000 \u0000We also encourage attendees to attend the keynote and invited talk presentations.

Code Mobility can be used to thwart code analysis and debugging by removing parts of the code from the deployed software program and installing it at run-time by downloading binary code blocks from a trusted server.

While promising, the dynamism of MTD introduces challenges related to understanding and quantifying the impact of MTD systems on security, users, and attackers. To analyze this impact, both the concepts of MTD systems and cyber attacks must be formalized. While a theory of MTD systems was proposed in [18], this paper presents a theory of cyber attacks that supports the understanding and analysis of the interaction between MTD systems and the attacks they hope to thwart. The theory defines key concepts that support precise discussion of attacker knowledge, attack types, and attack instances. The paper also presents concrete examples to show how these definitions and concepts can be used in realistic scenarios.","PeriodicalId":20578,"journal":{"name":"Proceedings of the Second ACM Workshop on Moving Target Defense","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84151516","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}

In this paper, we aim at modeling and evaluating the effectiveness of proactive cyber maneuvers to protect the critical path between a source-destination pair for mission operations in a mobile ad-hoc network (MANET) in the presence of an adversary. We propose a generic framework to analytically model cyber maneuvers and define their associated utilities. With the proposed framework, we develop the optimal solution to maximize the lifetime of the critical path with security assurance. We find that sufficient statistical information in the network is vital for the network defender to be proactive, choose the best cyber maneuvers to protect the critical path, and consequently outperform conventional reactive strategies. We also use simulations to validate the effectiveness of our solution.","PeriodicalId":20578,"journal":{"name":"Proceedings of the Second ACM Workshop on Moving Target Defense","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78475156","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}
