General Behavioral Characterization of Proximity Malware

CHAPTER 1

INTRODUCTION

  1. GENERAL

A delay-tolerant network is anetworkdesigned to use effectively over extreme ranges such as those encountered in space communications or with an interplanetary range. In this environment, longlatency-- sometimes assessed in time or days -- is unavoidable. The attractiveness of mobile consumer electronics, like laptop computers, PDAs, and recently and prominently, smart mobile phones, revives the delay-tolerant-network (DTN) model instead of the traditional infrastructure model. The wide-spread adoption of these devices, in conjunction with strong economic bonuses, induces a course of malware that specifically targets DTNs. We call this course of malware proximity malware. Proximity malware based on the DTN model brings unique security problems that aren't within the infrastructure model. In the infrastructure model, the cellular carrier centrally screens networks for abnormalities additionally the tool scarcity of individual nodes limits the pace of malware propagation. A prerequisite to defending against proximity malware is to identify it. On this paper, we look at a basic behavioral characterization of proximity malware. Behavioral characterization, in conditions of system call and program flow, has been previously proposed as an effective alternative to style coordinating for malware detection. In our model, malware-infected nodes manners are observed by others during their multiple opportunistic encounters: Individual observations may be imperfect, but unnatural behaviors of afflicted nodes are identifiable in the long-run.

  1. OBJECTIVE

Network is the combo of Nodes. Each node will communicate with its neighbours and talk about their data. When a node is influenced by way of a malware it's necessary to clear it else its neighborhood friends will talk to it and they also affected by malware. Hence recognition of malware is important. Here we discuss some methods for the recognition of malware.

  1. EXISTING SYSTEM

Previous studies quantify the threat of proximity malware strike and illustrate the probability of launching this attack, which is affirmed by recent information on hijacking hotel Wi-Fi hotspots for drive-by malware invasion. While using adoption of new short-range communication systems such as NFC and Wi-Fi Direct that aid spontaneous mass data transfer between spatially proximate mobile devices, the risk of proximity malware is becoming more genuine and relevant than ever. Proximity malware predicated on the DTN model brings unique security challenges that are not present in the model.

  1. EXISTING SYSTEM DISADVANTAGES
  • Central monitoring and learning resource limits are absent in the DTN model.
  • Very risk to collecting information and also having inadequate evidence.
  • It is filtering the false proof in sequentially and distributed.

LITERATURE SURVEY

Title: An Optimal Distributed Malware IMMUNE SYSTEM for Mobile Networks with Heterogeneous Devices

Author: Yong Li, Skillet Hui

Year: 2011

Description: Consider a mobile network in which a part of the nodes are attacked by malware. Our research problem is to deploy an efficient immune system to help the infected nodes to recover preventing the healthy nodes from further infection. Typically, we ought to disseminate the content-based signatures of known malware to as many nodes as possible. The signature is obtained by using algorithms such as an MD5 hash in the malware content, and they are used by the mobile devices to discover various patterns in the malware and then to disable further propagation. Therefore, distributing these signatures into the entire network while keeping away from unneeded redundancy is our search engine optimization goal.

Title: On Modeling Malware Propagation in Generalized Friendly Networks

Author: Shin-Ming Cheng

Year : 2011

Description: This article proposes a novel analytical model to efficiently analyze the swiftness and severity for growing the hybrid malware such as Commwarrior that focuses on media messaging service (MMS) and BT. Validation against conducted simulation tests reveals that our model developed from the Susceptible-Infected (SI) model in epidemiology accurately

Approximates mixed dispersing behaviors in large areas without the huge computational cost, which helps calculate the damages triggered by the cross malware and supports the introduction of diagnosis and containment procedures.

Title: Scalable, Behavior-Based Malware Clustering

Author: Ulrich Bayer

Year : 2009

Description: In this research, we propose a scalable clustering method of identify and group malware samples that exhibit similar behavior. Because of this, we first perform energetic analysis to obtain the execution traces of malware programs. These execution traces are then generalized into behavioral information, which characterize the experience of a program in more abstract terms. The profiles serve as insight to an efficient clustering algorithm which allows us to handle sample pieces that are an order of magnitude larger than previous approaches. We have applied our system to real-world malware series. The results display that our technique is able to realize and group malware programs that respond similarly, achieving a better precision than past strategies. To underline the scalability of the system, we clustered a couple of more than 75 thousand samples in less than three hours.

Title: Self-Policing Mobile Ad-Hoc Networks by Reputation Systems

Author: Sonja Buchegger

Year : 2005

Description: Node misbehavior anticipated to selfish or destructive reasons or faulty nodes can significantly degrade the performance of mobile ad-hoc systems. To handle misbehavior in such self-organized networks, nodes need to be able to automatically change their technique to changing degrees of cooperation. Existing solutions such as economical bonuses or secure routing by cryptography alleviate some of the problems, but not all. We explain the use of an self-policing mechanism predicated on reputation to enable mobile ad-hoc systems to keep operating despite the occurrence of misbehaving nodes. The reputation system in all nodes makes them discover misbehavior locally by observation and use of second-hand information. Once a misbehaving node is diagnosed it is automatically isolated from the network. We classify the top features of such reputation systems and express possible implementations of every of these. We explain in particular how you'll be able to use second-hand information while mitigating contamination by spurious ratings.

Title: The EigenTrust Algorithm for Reputation Management in P2P Networks

Author: Sepandar D. Kamvar, Mario T. Schlosser

Year : 2003

Description: Peer-to-peer file-sharing networks are currently acquiring much attention as a way of showing and distributing information. However, as recent experience shows, the private, open nature of the networks provides an almost ideal environment for the get spread around of Self-replicating inauthentic data. We illustrate an algorithm to diminish the amount of downloads of inauthentic files in a peer-to-peer file-sharing network that assigns each peer a distinctive global trust value, predicated on the peer's history of uploads. We present a sent out and secure method to compute global trust worth, based on Power iteration. Insurance agencies peers use these global trust values to choose the peers from whom they download, the network effectively identifies harmful peers and isolates them from the network. In simulations, this reputation system, called EigenTrust, has been proven to significantly decrease the quantity of inauthentic data files on the network, even under a variety of conditions where harmful peers cooperate so that they can deliberately subvert the system.

Title: When Gossip is Good: Distributed Probabilistic Inference for Diagnosis of Slow Network Intrusions

Author: Denver Dash, Branislav Kveton

Year : 2006

Description: Intrusion attempts credited to self-propagating code are becoming an increasingly urgent problem, partly because of the homogeneous make-up of the internet. Recent innovations in anomaly centered intrusion detection systems (IDSs) have made use of the quickly distributing nature of these attacks to identify them with high sensitivity with low phony positive (FP) rates. However, little by little propagating episodes are a lot more difficult to identify because they are cloaked under the veil of normal network traffic, yet can be equally as dangerous due to their exponential spread style. We extend the idea of using collaborative IDSs to corroborate the probability of invasion by imbuing end hosts with probabilistic visual models and using random messaging to gossip point out among peer detectors. We show that such a system can boost a fragile anomaly

Detector D to detect an order-of-magnitude slower worm, at wrong positive rates significantly less than a few per week, than would be possible using D by itself at the end-host or over a network aggregation point.

Title: A Preliminary Investigation of Worm Attacks in a Bluetooth Environment

Author: Jing Su, Kelvin K. W. Chan

Year : 2006

Description: Over days gone by year, there were several records of destructive code exploiting vulnerabilities in the Bluetooth process. As the research community has started to investigate a diverse set of Bluetooth security issues, little is known about the feasibility and the propagation dynamics of the worm in a Bluetooth environment. This paper is an preliminary attempt to cure this situation. We start by displaying that the Bluetooth process design and implementation is large and complex. We gather traces and we use managed experiments to research whether a large-scale Bluetooth worm outbreak is feasible today. Our data implies that starting a Bluetooth worm an infection is simple, once vulnerability is observed. Finally, we use trace-drive simulations to look at the propagation dynamics of Bluetooth worms. We find that Bluetooth worms can infect a huge population of vulnerable devices relatively quickly, in simply a few days.

Title: An adaptive anomaly detector for worm detection

Author: John Make Agosta, Carlos Diuk-Wasser

Year : 2007

Description: We present an adaptive end-host anomaly detector in which a supervised classifier trained as a traffic predictor is utilized to control a time-varying diagnosis threshold. Training and testing it on real traffic traces collected from a number of end-hosts, we show our detector dominates a preexisting fixed threshold detector. This comparability is solid to the decision of off-the-shelf classifier hired, and to a variety of performance criteria: the predictor's mistake rate, the reduction in the "threshold difference" and the capability to detect the simulated risk of incremental worm traffic added to the traces. This detector is supposed as part of a allocated worm recognition system that infers system-wide risks from end-host detections, in that way preventing the sensing and source limitations of classic centralized systems. The sent out system places a constraint upon this end coordinator detector to appear consistent as time passes and machine variability.

Title: CPMC: An Efficient Proximity Malware Coping System in Smartphone-based Mobile Networks

Author: Feng Li, Yinying Yang

Year : 2010

Description: Many emerging malware can utilize the proximity of devices to propagate in a distributed manner, thus remaining unobserved and making detections considerably more challenging. Not the same as existing malware coping schemes, which are either totally centralized or simply distributed, we propose a Community-based Proximity Malware Coping scheme, CPMC. CPMC utilizes the sociable community structure, which reflects a well balanced and controllable granularity of security, in smart phone-based mobile networks. The CPMC plan integrates short-term coping components, which package with individual malware and long-term analysis components, that offer vulnerability analysis towards person nodes. A closeness-oriented delegation forwarding scheme coupled with a community level quarantine method is proposed as the short-term coping components. These components contain a proximity malware by quickly propagating the personal of a recognized malware into all neighborhoods while avoiding needless redundancy.

  1. PROPOSED SYSTEM

Behavioral characterization, in conditions of system call and program circulation, has been previously proposed as a powerful alternative to style complementing for malware recognition. Inside our model, malware-infected nodes' conducts are observed by others throughout their multiple opportunistic encounters: Specific observations may be imperfect, but irregular behaviors of contaminated nodes are identifiable in the long-run. We identify difficulties for increasing Bayesian malware detection to DTNs, and propose a powerful method, look-ahead, to address the difficulties. Furthermore, we propose two extensions to look-ahead, dogmatic filtering and adaptive look-ahead, to address the task of "malicious nodes sharing bogus evidence".

  1. PROPOSED SYSTEM ADVANTAGES
  • Real mobile network traces are being used to verify the effectiveness of the proposed methods.
  • The proposed research consolidation strategies in reducing the negative impact of liars on the shared evidence's quality.
  • It is utilized to identify the abnormal actions of contaminated nodes in the long-run.

CHAPTER 2

PROJECT DESCRIPTION

2. 1. GENERAL

We analyze the problem of behavioral characterization of malware nodes in Wait Tolerant Network efficiently without impacting network performance.

2. 2. PROBLEM DEFINITION

Proximity malware is a harmful program that disrupts the web host node's normal function and has a chance of duplicating itself to other nodes during (opportunistic) contact opportunities between nodes in the DTN. When duplication occurs, the other node is infected with the malware. We present an over-all behavioral characterization of proximity malware, which captures the practical but imperfect aspect in detecting proximity malware. Beneath the behavioral malware characterization, and with a straightforward cut-off malware containment strategy, we formulate the malware diagnosis process as a sent out decision problem. We analyze the risk from the decision, and design a straightforward, yet effective, strategy, look-ahead, which by natural means reflects specific nodes' intrinsic risk inclinations against malware infection. We present two choice techniques, dogmatic filtering and adaptive look-ahead, that in a natural way prolong look-ahead to combine research provided by others, while filled with the negative aftereffect of false evidence. A good property of the suggested evidence loan consolidation methods is usually that the results will not aggravate even if liars are the bulk in the neighborhood

2. 3. METHODOLOGIES

Methodologies are the process of studying the rules or process of behavioral characterizing of node with two methods, dogmatic filtering and adaptive look-ahead, for consolidating data provided by other nodes, while formulated with the negative impact of liars in wait tolerant network.

2. 3. 1. MODULES

  • Authentication
  • Network Nodes
  • Malware Detection
  • Evidence Analysis
  • Evil Node Revocation

2. 3. 2 MODULE DESCRIPTION

  • Authentication

If you will be the new user going to consume the service they have to register first by providing necessary details. After successful completion of sign up process, an individual must login into the application by providing username and exact password. The user must provide exact account that was provided during enrollment, if login success means it will require up to main page else it will remain in the login web page itself. .

  • Network Nodes

Under this module, the network nodes which are interconnected by geographic area network, that node ip will be fetched in order to share the resources among the list of network. As well as the performance of individual system have been analyzed to examine the behavior

  • Malware Detection

Malware detection module helps to identify the evil node which is damaged by malware program

  • Evidence Analysis

This module used to investigate about evidences of nodes by collecting assessments before a normal node get affected by malware program. Data aging process helps to discard out-of-date assessments of your node and proof consolidation helps to filter negative assessments of your node provided by the other nodes.

  • Evil Node Revocation

After diagnosis of evil node, we have to drop the communication recover in order to avoid from malware growing and the evil node details are used in database for even more reference point. Finally evil node gets revoked from the network computer list.

2. 4. TECHNIQUE USED

Dogmatic filtering

Dogmatic filtering is dependant on the observation that one's own assessments are truthful and for that reason, can be used to bootstrap the data loan consolidation process. A node shall only recognize evidence that will not sway its current opinion too much. We call this observation the dogmatic principle.

Adaptive look-ahead

Adaptive look in advance takes a different way towards evidence consolidation. Instead of deciding whether to make use of the evidence provided by others straight in the cut-off decision, adaptive look ahead indirectly uses the evidence by adapting the steps to look forward to the variety of view.
