Corporate Security: Using Knowledge Construction To Define A Practising Body Of Knowledge, David Brooks
Corporate Security: Using Knowledge Construction To Define A Practising Body Of Knowledge, David Brooks
Research outputs 2012
Security is a multidimensional concept, with many meanings, practising domains, and heterogeneous occupations. Therefore, it is difficult to define security as a singular concept, although understanding may be achieved by its applied context in presenting a domicile body of knowledge. There have been studies that have presented a number of corporate security bodies of knowledge; however, there is still restricted consensus. From these past body of knowledge studies, and supported by multidimensional scaling knowledge mapping, a body of knowledge framework is put forward, integrating core and allied knowledge categories. The core knowledge categories include practise areas such as risk management, …

Profit-Maximizing Firm Investments In Customer Information Security, Yong Yick Lee, Robert J. Kauffman, Ryan Sougstad
Research Collection School Of Computing and Information Systems
When a customer interacts with a firm, extensive personal information often is gathered without the individual's knowledge. Significant risks are associated with handling this kind of information. Providing protection may reduce the risk of the loss and misuse of private information, but it imposes some costs on both the firm and its customers. Nevertheless, customer information security breaches still may occur. They have several distinguishing characteristics: (1) typically it is hard to quantify monetary damages related to them; (2) customer information security breaches may be caused by intentional attacks, as well as through unintentional organizational and customer behaviors; and (3) …
Fraud Detection In Online Consumer Reviews, Nan Hu, Ling Liu, Vallabh Sambamurthy
Fraud Detection In Online Consumer Reviews, Nan Hu, Ling Liu, Vallabh Sambamurthy
Research Collection School Of Computing and Information Systems
Increasingly, consumers depend on social information channels, such as user-posted online reviews, to make purchase decisions. These reviews are assumed to be unbiased reflections of other consumers' experiences with the products or services. While extensively assumed, the literature has not tested the existence or non-existence of review manipulation. By using data from Amazon and Barnes & Noble, our study investigates if vendors, publishers, and writers consistently manipulate online consumer reviews. We document the existence of online review manipulation and show that the manipulation strategy of firms seems to be a monotonically decreasing function of the product's true quality or the …

Information Risk And Underwriter Switching In Seos: Evidence From China, Wei Luo, Pingui Rao, Heng Yue
Information Risk And Underwriter Switching In Seos: Evidence From China, Wei Luo, Pingui Rao, Heng Yue
Research Collection School Of Accountancy
In this paper we examine whether information risk affects underwriter switching in a seasoned equity offering (SEO) process. Building on previous research, we hypothesize that SEO firms and underwriters associate with one another by mutual choice, and firms with a low degree of information risk tend to match up with prestigious underwriters. Using a sample of SEO firms in China and employing accruals quality as a proxy of information risk, we find evidence consistent with our hypothesis: the information risk and the initial public offering (IPO) underwriters’ reputation at the time of the SEO jointly determine the probability that the …
A Hybrid Method To Detect Deflation Fraud In Cost-Per-Action Online Advertising, Xuhua Ding
A Hybrid Method To Detect Deflation Fraud In Cost-Per-Action Online Advertising, Xuhua Ding
Research Collection School Of Computing and Information Systems
Web advertisers prefer the cost-per-action (CPA) advertisement model whereby an advertiser pays a web publisher according to the actual amount of transactions, rather than the volume of advertisement clicks. The main obstacle for a wide deployment of this model is the deflation fraud. Namely, a dishonest advertiser under-reports the transaction count in order to discharge less. In this paper, we present a mechanism to detect such a fraud using a hybrid of cryptography and probability tools. With the assistance from a small number of users, the publisher can detect deflation fraud with a success probability growing exponentially with the fraud …

What Does Security Culture Look Like For Small Organizations?, Patricia A. Williams
What Does Security Culture Look Like For Small Organizations?, Patricia A. Williams
Australian Information Security Management Conference
The human component is a significant factor in information security, with a large numbers of breaches occurring due to unintentional user error. Technical solutions can only protect information so far and thus the human aspect of security has become a major focus for discussion. Therefore, it is important for organisations to create a security conscious culture. However, currently there is no established representation of security culture from which to assess how it can be manoeuvred to improve the overall information security of an organization. This is of particular importance for small organizations who lack the resources in information security and …

Exploring The Relationship Between Organizational Culture And Information Security Culture, Joo S. Lim, Shanton Chang, Sean Maynard, Atif Ahmad
Australian Information Security Management Conference
Managing Information Security is becoming more challenging in today’s business because people are both a cause of information security incidents as well as a key part of the protection from them. As the impact of organizational culture (OC) on employees is significant, many researchers have called for the creation of information security culture (ISC) in organizations to influence the actions and behaviour of employees towards better organizational information security. Although researchers have called for the creation of ISC to be embedded in organizations, nonetheless, literature suggests that little past research examining the relationship between the nature of OC and ISC. …
Wireless Networks: Certificateless Id-Based Authentication Using Threshold Signature For P2p Manets, Aasia Samreen, Seema Ansari
Wireless Networks: Certificateless Id-Based Authentication Using Threshold Signature For P2p Manets, Aasia Samreen, Seema Ansari
International Conference on Information and Communication Technologies
As far as the security of MANET (mobile and ad hoc network) is concerned, it depends upon the secure authentication especially for P2P MANETs. Identity based encryption was introduced to construct Public Key without requiring a certificate. Therefore, certificateless authentication combined with threshold digital signature and efficient key generation using identities such as IP address, are the challenging issues in front of researchers. In this paper we have addressed the problem of identity based secure authentication employing well-known RSA algorithm and secret sharing to generate threshold signature on a message.

Establishing The Human Firewall: Reducing An Individual's Vulnerability To Social Engineering Attacks, Jamison W. Scheeres
Establishing The Human Firewall: Reducing An Individual's Vulnerability To Social Engineering Attacks, Jamison W. Scheeres
Theses and Dissertations
Hackers frequently use social engineering attacks to gain a foothold into a target network. This type of attack is a tremendous challenge to defend against, as the weakness lies in the human users, not in the technology. Thus far, methods for dealing with this threat have included establishing better security policies and educating users on the threat that exists. Existing techniques aren’t working as evidenced by the fact that auditing agencies consider it a given that will be able to gain access via social engineering. The purpose of this research is to propose a better method of reducing an individual’s …

An Information-Sharing Based Anti-Phishing System, Yueqing Cheng, Zhen Yuan, Lei Ma, Robert H. Deng
An Information-Sharing Based Anti-Phishing System, Yueqing Cheng, Zhen Yuan, Lei Ma, Robert H. Deng
Research Collection School Of Computing and Information Systems
This paper presents the design of an informationsharing based or server-assisted anti-phishing system. The system follows a client-server architecture and makes decision based on not only client side heuristics but also collective information from multiple clients. When visiting a web site, a client side proxy, installed as a plug-in to a browser, decides on the legitimacy of the web site based on a combination of white list, black list and heuristics. In case the client side proxy does not have sufficient information to make a clear judgment, it reports the suspicious site to a central server which has access to …

Factors Impacting Key Management Effectiveness In Secured Wireless Networks, Yongjoo Shin
Factors Impacting Key Management Effectiveness In Secured Wireless Networks, Yongjoo Shin
Theses and Dissertations
The use of a Public Key Infrastructure (PKI) offers a cryptographic solution that can overcome many, but not all, of the MANET security problems. One of the most critical aspects of a PKI system is how well it implements Key Management. Key Management deals with key generation, key storage, key distribution, key updating, key revocation, and certificate service in accordance with security policies over the lifecycle of the cryptography. The approach supported by traditional PKI works well in fixed wired networks, but it may not appropriate for MANET due to the lack of fixed infrastructure to support the PKI. This …

Using Prospect Theory To Investigate Decision-Making Bias Within An Information Security Context, Neil J. Schroeder
Theses and Dissertations
Information security is an issue that has increased in importance over the past decade. In this time both practitioner and academic circles have researched and developed practices and process to more effectively handle information security. Even with growth in these areas there has been little research conducted into how decision makers actually behave. This is problematic because decision makers in the Department of Defense have been observed exhibiting risk seeking behavior when making information security decisions that seemingly violate accepted norms. There are presently no models in the literature that provide sufficient insight into this phenomenon. This study used Prospect …

Technology Competition And Optimal Investment Timing: A Real Options Perspective, Robert J. Kauffman, X. Li
Research Collection School Of Computing and Information Systems
Companies often choose to defer irreversible investments to maintain valuable managerial flexibility in an uncertain world. For some technology-intensive projects, technology uncertainty plays a dominant role in affecting investment timing. This article analyzes the investment timing strategy for a firm that is deciding about whether to adopt one or the other of two incompatible and competing technologies.We develop a continuous-time stochastic model that aids in the determination of optimal timing for managerial adoption within the framework of real options theory. The model captures the elements of the decision-making process in such a way so as to provide managerial guidance in …
