Notice And Consent In A World Of Big Data, Fred H. Cate, Viktor Mayer-Schönberger

Articles by Maurer Faculty

• Nowadays individuals are often presented with long and complex privacy notices routinely written by lawyers for lawyers, and are then requested to either ‘consent’ or abandon the use of the desired service.
• The over-use of notice and consent presents increasing challenges in an age of ‘Big Data’.
• These phenomena are receiving attention particularly in the context of the current review of the OECD Privacy Guidelines.
• In 2012 Microsoft sponsored an initiative designed to engage leading regulators, industry executives, public interest advocates, and academic experts in frank discussions about the role of individual control and notice and consent in data protection …

Improving Internet Security Through Information Disclosure: A Field Quasi-Experiment, Qian Tang, Leigh L. Linden, John S. Quarterman, Andrew B. Whinston

Research Collection School Of Computing and Information Systems

Cybersecurity is a national priority in this big data era. Because of negative externalities and the resulting lack of economic incentives, companies often underinvest in security controls, despite government and industry recommendations. Although many existing studies on security have explored technical solutions, only a few have looked at the economic motivations. To fill the gap, we propose an approach to increase the incentives of organizations to address security problems. Specifically, we utilize and process existing security vulnerability data, derive explicit security performance information, and disclose the information as feedback to organizations and the public. We regularly release information on the …

Guardian: Hypervisor As Security Foothold For Personal Computers, Yueqiang Cheng, Xuhua Ding

Research Collection School Of Computing and Information Systems

Personal computers lack of a security foothold to allow the end-users to protect their systems or to mitigate the damage. Existing candidates either rely on a large Trusted Computing Base (TCB) or are too costly to widely deploy for commodity use. To fill this gap, we propose a hypervisor-based security foothold, named as Guardian, for commodity personal computers. We innovate a bootup and shutdown mechanism to achieve both integrity and availability of Guardian. We also propose two security utilities based on Guardian. One is a device monitor which detects malicious manipulation on camera and network adaptors. The other is hyper-firewall …

Accountable Trapdoor Sanitizable Signatures, Junzuo Lai, Xuhua Ding, Yongdong Wu

Research Collection School Of Computing and Information Systems

Sanitizable signature (SS) allows a signer to partly delegate signing rights to a predetermined party, called sanitizer, who can later modify certain designated parts of a message originally signed by the signer and generate a new signature on the sanitized message without interacting with the signer. One of the important security requirements of sanitizable signatures is accountability, which allows the signer to prove, in case of dispute, to a third party that a message was modified by the sanitizer. Trapdoor sanitizable signature (TSS) enables a signer of a message to delegate the power of sanitization to any parties at anytime …

Verifiable And Private Top-K Monitoring, Xuhua Ding, Hwee Hwa Pang

Research Collection School Of Computing and Information Systems

In a data streaming model, records or documents are pushed from a data owner, via untrusted third-party servers, to a large number of users with matching interests. The match in interest is calculated from the correlation between each pair of document and user query. For scalability and availability reasons, this calculation is delegated to the servers, which gives rise to the need to protect the privacy of the documents and user queries. In addition, the users need to guard against the eventuality of a server distorting the correlation score of the documents to manipulate which documents are highlighted to certain …

A Secure Platform For Information Sharing In Epcglobal Network, Jie Shi, Yingjiu Li, Robert H. Deng, Wei He, Eng Wah Lee

Research Collection School Of Computing and Information Systems

With the rapid development of RFID technology, the EPCglobal network has drawn considerable attention from both research and industry communities, which enables supply chain partners to automatically share information and improve the visibility of supply chains. As the information shared in the EPCglobal network is usually sensitive and valuable, security mechanisms should be provided. In this paper, we aim at designing and implementing a secure information sharing platform in the EPCglobal network with a focus on authorization mechanism. We also design and implement a track and trace application based on the proposed secure platform so as to demonstrate its feasibility …

Experimenting With Anomaly Detection By Mining Large-Scale Information Networks, A. Taleb-Bendiab

Australian Information Security Management Conference

Social networks have formed the basis of many studies into large networks analysis. Whilst much is already known regarding efficient algorithms for large networks analysis, data mining, knowledge diffusion, anomaly detection, viral marketing, to mention. More recent research is focussing on new classes of efficient approximate algorithms that can scale to billion nodes and edges. To this end, this paper presents an extension of an algorithm developed originally to analyse large scale-free autonomic networks called the Global Observer Model. In this paper, the algorithm is studied in the context of monitoring large-scale information networks. Hence, taking into account the size …

A Proposed Formula For Comparing Kill Password Effectiveness In Single Password Rfid Systems, Christopher Bolan

Australian Information Security Management Conference

The Electronic Product Code standard for RFID systems plays a significant role in worldwide RFID implementations. A feature of the RFID standards has been the RFID Kill command which allows for the "permanent" destruction of an RFID tag through the issuing of a simple command. Whilst the inclusion of this command may be vital for user privacy it also opens up significant avenues for attack. Whilst such attacks may be well documented there has been little to no discussion of the efficacy of the differing mitigation approaches taken. A simple formula to calculate the full timing of such an attack …

Harms: Hierarchical Attack Representation Models For Network Security Analysis, Jin Hong, Dong-Seong Kim

Australian Information Security Management Conference

Attack models can be used to assess network security. Purely graph based attack representation models (e.g., attack graphs) have a state-space explosion problem. Purely tree-based models (e.g., attack trees) cannot capture the path information explicitly. Moreover, the complex relationship between the host and the vulnerability information in attack models create difficulty in adjusting to changes in the network, which is impractical for modern large and dynamic network systems. To deal with these issues, we propose hierarchical attack representation models (HARMs). The main idea is to use two-layer hierarchy to separate the network topology information (in the upper layer) from the …

An Information Security Awareness Capability Model (Isacm), Robert Poepjes, Michael Lane

Australian Information Security Management Conference

A lack of information security awareness within some parts of society as well as some organisations continues to exist today. Whilst we have emerged from the threats of late 1990s of viruses such as Code Red and Melissa, through to the phishing emails of the mid 2000’s and the financial damage some such as the Nigerian scam caused, we continue to react poorly to new threats such as demanding money via SMS with a promise of death to those who won’t pay. So is this lack of awareness translating into problems within the workforce? There is often a lack of …

Human-Readable Real-Time Classifications Of Malicious Executables, Anselm Teh, Arran Stewart

Australian Information Security Management Conference

Shafiq et al. (2009a) propose a non–signature-based technique for detecting malware which applies data mining techniques to features extracted from executable files. Their technique has a high level of accuracy, a low false positive rate, and a speed on par with commercial anti-virus products. One portion of their technique uses a multi-layer perceptron as a classifier, which provides little insight into the reasons for classification. Our experience is that network security analysts prefer tools which provide human-comprehensible reasons for a classification, rather than operating as “black boxes”. We therefore build on the results of Shafiq et al. by demonstrating a …

Implementing A Secure Academic Grid System - A Malaysian Case, Mohd Samsu Sajat, Suhaidi Hassan, Adi Affandi Ahmad, Ali Yusny Daud, Amran Ahmad

Australian Information Security Management Conference

Computational grids have become very popular in the recent times due to their capabilities and flexibility in handling large computationally intensive jobs. When it comes to the implementation of practical grid systems, security plays a major role due to the confidentiality of the information handled and the nature of the resources employed. Also due to the complex nature of the grid operations, grid systems face unique security threats compared to other distributed systems. This paper describes how to implement a secure grid system with special emphasis on the steps to be followed in obtaining, implementing and testing PKI certificates.

Web-Based Risk Analysis For Home Users, R. T. Magaya, N. L. Clarke

Australian Information Security Management Conference

The advancement of the Internet has provided access to a wide variety of online services such as banking, e-commerce, social networking and entertainment. The wide availability and popularity of the Internet has also led to the rise in risks and threats to users, as criminals have taken an increasingly active role in abusing innocent users. Current risk analysis tools, techniques and methods available do not cater for home users but are tailored for large organisations. The tools require expertise to use them and they are expensive to purchase. What is available for home users are generic information portals that provide …

An Investigation Into The Wi-Fi Protected Setup Pin Of The Linksys Wrt160n V2, Symon Aked, Christopher Bolan, Murray Brand

Australian Information Security Management Conference

Wi-Fi Protected Setup (WPS) is a method of allowing a consumer to set up a secure wireless network in a user friendly way. However, in December 2011 it was discovered that a brute force attack exists that reduces the WPS key space from 108 to 104+103. This resulted in a proof of concept tool that was able to search all possible combinations of PINs within a few days.This research presents a methodology to test wireless devices to determine their susceptibility to the external registrar PIN authentication design vulnerability. A number of devices were audited, and the Linksys WRT160N v2 router …

Exposing Potential Privacy Issues With Ipv6 Address Construction, Clinton Carpene, Andrew Woodward

Australian Information Security Management Conference

The usage of 128 bit addresses with hexadecimal representation in IPv6 poses significant potential privacy issues. This paper discusses the means of allocating IPv6 addresses, along with the implications each method may have upon privacy in different usage scenarios. The division of address space amongst the global registries in a hierarchal fashion can provide geographical information about the location of an address, and its originating device. Many IPv6 address configuration methods are available, including DHCPv6, SLAAC (with or without privacy extensions), and Manual assignment. These assignment techniques are dissected to expose the identifying characteristics of each technique. It is seen …
