A System For Detecting Malicious Insider Data Theft In Iaas Cloud Environments, Jason Nikolai, Yong Wang
Faculty Research & Publications
The Cloud Security Alliance lists data theft and insider attacks as critical threats to cloud security. Our work puts forth an approach using a train, monitor, detect pattern which leverages a stateful rule based k-nearest neighbors anomaly detection technique and system state data to detect inside attacker data theft on Infrastructure as a Service (IaaS) nodes. We posit, instantiate, and demonstrate our approach using the Eucalyptus cloud computing infrastructure where we observe a 100 percent detection rate for abnormal login events and data copies to outside systems.

Semeo: A Semantic Equivalence Analysis Framework For Obfuscated Android Applications, Zhen Hu
Semeo: A Semantic Equivalence Analysis Framework For Obfuscated Android Applications, Zhen Hu
Department of Computer Science and Engineering: Dissertations, Theses, and Student Research
Software repackaging is a common approach for creating malware. In this approach, malware authors inject malicious payloads into legitimate applications; then, to ren- der security analysis more difficult, they obfuscate most or all of the code. This forces analysts to spend a large amount of effort filtering out benign obfuscated methods in order to locate potentially malicious methods for further analysis. If an effective mechanism for filtering out benign obfuscated methods were available, the number of methods that must be analyzed could be reduced, allowing analysts to be more productive. In this thesis, we introduce SEMEO, a highly effective and …

Knowledge Modeling Of Phishing Emails, Courtney Falk
Open Access Dissertations
This dissertation investigates whether or not malicious phishing emails are detected better when a meaningful representation of the email bodies is available. The natural language processing theory of Ontological Semantics Technology is used for its ability to model the knowledge representation present in the email messages. Known good and phishing emails were analyzed and their meaning representations fed into machine learning binary classifiers. Unigram language models of the same emails were used as a baseline for comparing the performance of the meaningful data. The end results show how a binary classifier trained on meaningful data is better at detecting phishing …
Significant Permission Identification For Android Malware Detection, Lichao Sun
Significant Permission Identification For Android Malware Detection, Lichao Sun
Department of Computer Science and Engineering: Dissertations, Theses, and Student Research
A recent report indicates that a newly developed malicious app for Android is introduced every 11 seconds. To combat this alarming rate of malware creation, we need a scalable malware detection approach that is effective and efficient. In this thesis, we introduce SigPID, a malware detection system based on permission analysis to cope with the rapid increase in the number of Android malware. Instead of analyzing all 135 Android permissions, our approach applies 3-level pruning by mining the permission data to identify only significant permissions that can be effective in distinguishing benign and malicious apps. Based on the identified significant …

Ultrasonic Data Steganography, Alexander Orosz Edwards
KSU Journey Honors College Capstones and Theses
What started off as a question on the possibly of data transmission via sound above the level of human hearing evolved into a project exploring the possibility of ultrasonic data infiltration and exfiltration in an information security context. It is well known that sound can be used to transmit data as this can be seen in many old technologies, most notably and simply DTMF tones for phone networks. But what if the sound used to transmit signals was in in the ultrasonic range? It would go generally unnoticed to anyone not looking for it with tools such as a spectrum …

Empirical Analysis Of Socio-Cognitive Factors Affecting Security Behaviors And Practices Of Smartphone Users, Joseph P. Simpson
CCE Theses and Dissertations
The overall security posture of information systems (IS) depends on the behaviors of the IS users. Several studies have shown that users are the greatest vulnerability to IS security. The proliferation of smartphones is introducing an entirely new set of risks, threats, and vulnerabilities. Smartphone devices amplify this data exposure problem by enabling instantaneous transmission and storage of personally identifiable information (PII) by smartphone users, which is becoming a major security risk. Moreover, companies are also capitalizing on the availability and powerful computing capabilities of these smartphone devices and developing a bring-your-own-device (BYOD) program, which makes companies susceptible to divulgence …

A Privacy Gap Around The Internet Of Things For Open-Source Projects, Brian Cusack, Reza Khaleghparast
Australian Information Security Management Conference
The Internet of Things (IoT) is having a more important role in the everyday lives of people. The distribution of connectivity across social and personal interaction discloses personalised information and gives access to a sphere of sensitivities that were previously masked. Privacy measures and security to protect personal sensitivities are weak and in their infancy. In this paper we review the issue of privacy in the context of IoT open-source projects, and the IoT security concerns. A proposal is made to create a privacy bubble around the interoperability of devices and systems and a filter layer to mitigate the exploitation …

Using Graphic Methods To Challenge Cryptographic Performance, Brian Cusack, Erin Chapman
Australian Information Security Management Conference
Block and stream ciphers have formed the traditional basis for the standardisation of commercial ciphers in the DES, AES, RC4, and so on. More recently alternative graphic methods such as Elliptic Curve Cryptography (ECC) have been adopted for performance gains. In this research we reviewed a range of graphic and non-graphic methods and then designed our own cipher system based on several graphic methods, including Visual Cryptography (VC). We then tested our cipher against RC4 and the AES algorithms for performance and security. The results showed that a graphics based construct may deliver comparable or improved security and performance in …

Lastly, we lay the foundation for future work around additional collaborative metrics, features and …
The Corporate Security Stratum Of Work: Identifying Levels Of Work In The Domain, Codee Roy Ludbey
The Corporate Security Stratum Of Work: Identifying Levels Of Work In The Domain, Codee Roy Ludbey
Theses : Honours
Corporate security is a practicing domain and developing academic discipline that provides for the protection of people, information and assets, as well as the self-protection of organisations. Fayol (1949) articulated such an activity within organisations to be a core business function of significant importance; embedding security operations within all aspects of organisational work. This embedded nature of security within organisations has led to difficulty in the literature delineating roles and responsibilities of security practitioners; consequently leading to a nebulous understanding of security as a whole. Therefore, an investigation of the corporate security stratum of work has been undertaken to address …
