Segregation-of-duties conflicts in the insider threat landscape: an overview and case study

Many insider attacks originate from misuse of privileges granted by organizations to their internal employees, contractors or third-party service providers. A fundamental means of ensuring that conflicts of privilege cannot occur is to segregate role allocations in order to ensure that no individual can perform a task from beginning to end. In this paper, we provide background on insider attacks in connection with conflicts in Segregation of Duties, and present the current strategies for preventing and detecting such conflicts. To illustrate how a conflict can occur and what can result, we present an in-depth case study demonstrating a conflict in Segregation of Dutiesin an organization, along with the consequent fraud, and we discuss how it might have been prevented.

Investors’ behavior in an emerging, tax free market

We provide empirical evidence on the stock market participants’ behavior in an emerging market, with a tax-free environment. Our results show that UAE investors exhibit overconfidence and home bias, and tend to sell prior winners and buy prior losers. We find that investors rely on familiarity and on their information channels to make decisions. The results indicate that investors are risk averse, especially after the global financial crisis, which has had contagion effect on UAE markets. Investors attribute this effect to the inability to manage systemic crisis and to problems of information asymmetry, insider trading, and lack of good governance during crisis.

Management attitudes to corporate governance issues : evidence from Sri Lanka

This study investigates the attitudes of senior managers in Sri Lankan firms to governance issues using a countrywide cross-sectional survey. Respondents from 64 public firms provide information on manager's attitudes to internal control procedures: (1) producing misleading financial reports, (2) providing faulty investment advice, (3) permitting insider-trading, and (4) providing inaccurate advertising. We establish if these attitudes vary with 5 firm-specific factors: industry group, international exposure of firms, size, whether the firm was listed or not, and whether the firm had a written code of ethics. Employing ordinal logistic regression techniques, the results demonstrate significant variation by respondents within different types of firms. Specifically there was little variation to these issues when respondents were classified by industry, with most variation when classified by international involvement. Respondents from firms with significant international exposures were strongly opposed to most practices, while respondents from firms with written codes of ethics were strongly opposed to the production of misleading reports and insider-trading. Interestingly respondents from listed firms were most opposed to insider-trading, while smaller firms were more opposed to misleading advertising than respondents from larger firms. The results have important implications for the implementation of corporate governance practice.

Information disclosure and corporate governance in listed companies in China: from Yinguangxia to Enron

China's path to the development of a modern securities market has not been a smooth one. This article argues that efforts to impose Western securities market models on China have been fraught with difficulty. This is especially clear from the adoption of information disclosure principles and practices. While the integrity of disclosure practices is a fundamental element in maintaining investors' confidence in securities markets, disclosure practices need to be attuned to China '5 systemic features, especially in regard to its legal structure and rules. Market failures, such as the collapse of Enron in the United States, have led to a realisation that US disclosure models have their own difficulties and that these should not be uncritically used. This article reviews recent Chinese law andpractice (using the Yinguangxia false disclosure scandal as an example) in this area and calls for the adoption of a more critical approach towards the use of Western models with particular regard to China's own distinctive pathways of reform.

Corporate governance failure and its impact on National Australia Bank's performance

The National Australia Bank (NAB) is the largest financial services institution listed on the Australian stock exchange and is within the 30 most profitable financial services organisation in the world. In January 2004, the bank disclosed to the public that it had identified losses relating to unauthorised trading in foreign currency options amounting to AUD360 million. This foreign exchange debacle was classified as operational risk, the risk of loss resulting from inadequate or failed processes, people, or systems and reiterated the importance of corporate governance for banks. Concurrent issues of National Australia Bank’s AUD4.1 billion loss on US HomeSide loans in 2001, the degree of strength of their risk management practices and lack of auditor independence, were raised by the US Securities and Exchange Commission in 2004, reinforcing the view that corporate governance had not been given the priority it deserved over a number of years. This paper will assess and critically analyse the impact of corporate governance failure by management and Board of Directors on NAB’s performance over the years 2001-2005.

The information content of directors' trades: empirical analysis of the Australian market

We examine the trading activities of directors in shares of their own companies on the Australian Stock Exchange during the July-December 2005 period. We find that directors of small companies in particular earn abnormal return after both their 'Purchase' and as well as their 'Sale' trade. Directors of these companies have an uncanny ability to time the market by trading when mispricing is greatest, and are able to predict the future performance of their firms in short run. For directors of medium and large companies, we find evidence that 'Sale' trades are the ones which work as loss avoiders. Outsiders recognise to some extent that directors' trades are informative, however they are slow to incorporate the new information into prices, refuting much of the market efficiency literature.

Property transactions : a note on ethics

Some activities that are applied in the property market to facilitate transactions have the potential to lead to unethical behaviour. Two conditions required for a sale price to be acceptable as market value are that the transaction is at arm’s length and the parties to the transaction are knowledgeable and prudent. The well-known difficulties associated with access to market pricing information are exacerbated by several of these activities including dummy bidding at auctions, two-tier marketing and the provision of lease incentives. Added to these is a common requirement that any negotiation be commercial-in-confidence. The lack of information has the potential to distort the market and this has been well publicised in recent times particularly in the residential market.
The definition of market value is visited and the nature of ethics in property transactions is outlined. Several examples of activities that could lead to unethical behaviour are described. It is concluded that unethical behaviour is hard to identify. Some recommendations are included for consideration and discussion.

Insider research, the process and practice : issues arising from professionals conducting research within their own working environments

This thesis explores the chaotic, dynamic, ambiguous, complex and confusing world of the insider researcher. The proliferating species of insider researcher is common in public sector organisations and is particularly prevalent among post-graduate students who have combined study with work. Insider researchers range from the in-house researcher employed to conduct research to those who are conducting research in addition to their normal duties. This thesis, through five illustrative case-studies, discusses, reflects upon, explains, and clarifies the possibilities, limitations and the issues arising from a consideration of the practice of professionals conducting research in the large government education system in Victoria. The central focus of this thesis, that of exploring issues arising from professionals conducting research in their own working environments, has an importance that hitherto has had little direct recognition in the qualitative education research literature. And yet the practice of insider research is common and has a potentially large impact on the nature of the decision making process in public sector organisations. This relative invisibility in the social research literature of a discussion of issues relating to insider research demands to be made more visible. It is both useful and necessary to explore the particular possibilities, conditions and challenges of insiders conducting research in public organisations as the practice of insider research contines to grow. This thesis adds to the literature by locating insider research in a discussion of the wider soial context of ideology, culture, relationships, politics, language and meaning, and the decision-making process.

The role of optimistic news stories in IPO pricing

This study investigates the influence of optimistic news stories on first-day pricing of initial public offerings (IPOs) in Australia between 1995 and 2005. Unlike the United States, Australia has no quiet-period regulation limiting the dissemination of information from media before IPO listing dates. We find that optimistic news stories are negatively associated with IPO underpricing. Results from a relative valuation model show that IPOs which received positive news stories ahead of the first trading day are not overpriced relative to their industry benchmarks. These results suggest that optimistic news stories mitigate information asymmetry and adverse selection problems. However, optimistic news stories do not appear to inflate the share price on the first day of trading. Our findings suggest that regulation mandating a 'quiet period' before the commencement of trading in IPOs is neither necessary nor desirable in the Australian environment.

A perspective on credit derivatives

This contribution offers an explanation of credit derivatives as a group of financial instruments having a common purpose being the managing of credit exposures, and thus credit or default risk. This paper explores the links between their economic and financial manifestations and the legal bases for their widespread application. To ensure an understanding of the purposes served by each of the main types of credit derivatives, a detailed scrutiny of individual instruments is undertaken. Issues relating law and economics to trading in this type of derivative are investigated, then pricing issues and empirical evidence are considered. A summary brings together the range of features bearing upon the effective development of a market in these financial instruments.

Self-regulation: a risky option for developing countries? The case of Bangladesh

In recent years, the command and control type of government regulation is giving way to self- regulatory approaches in which industry sectors are responsible for controlling the conduct of their own members. Although self-regulatory approaches are increasingly being adopted with the objective of both improving the rate of compliance and reducing costs in developed countries, this paper argues that this might be a risky option. Developing countries often do not have adequate levels of standards of efficiency, effective legal regulatory frameworks, institutional safeguards and public awareness. Using the Bangladesh agriculture sector as an exemplar, this paper investigates the prospects of self-regulation of small businesses trading in agricultural inputs as a possible remedy for the recent problems associated with the sale of contaminated inputs to the farmers. The paper argues that self-regulation does not develop and is not sustained  independently of the context in which business operates. Importantly, the context includes the legal infrastructure created by the state and the enforcement effort imposed by the state. In the absence of effective state intervention in the public interest, institutional safeguards and public awareness, private entrepreneurs are less constrained to behave in the public interest and in conformity with the objectives of self-regulation. The findings of this paper provide significant implications for addressing the issue of effective regulation in developing countries.

Corporate social responsibility of small businesses: a developing country perspective

Corporate social responsibility (CSR) has emerged as an important concept for developing countries in recent years. This paper investigates the issues of CSR relating to small businesses that have emerged as a result of market-based reforms in developing countries, where the compliance of voluntary standards, code of conduct and regulations are limited. The paper argues that prevalence of corruption, lack of rule based governance, resource constraints for effective capacity building on the part of the state and lack of awareness have created a weak and unethical corporate culture leading to low levels of CSR in developing countries. Using Bangladesh agriculture sector as an exemplar, this paper investigates how small businesses trading in agricultural inputs with no brand capital and low public visibility are behaving in a socially irresponsible way, in an environment of inadequate regulatory sanctions and compliance by selling contaminated inputs to farmers who are mostly poor and not even aware of their rights. The low levels of CSR is undermining and also threatening the sustainability of the positive impact of the market-based reforms undertaken in this sector. The paper proposes that integrated governance linking state, private sector and civil society can promote good governance and better CSR relating to small businesses .

Rating downgrade and the price impact of CDS spread on stock return

We investigate the time-varying informativeness of credit default swap (CDS) trading on stock returns for 302 US firms from July 2004 to August 2010. Using the Acharya and Johnson (2007) measure, we find that CDS trading becomes informative for an increasing number of firms as we approach the global financial crisis (GFC). Firm numbers gradually decline post-GFC, but remain high compared to the pre-GFC period. furthermore, CDS trading imposes the largest conditional price impact on firms that are recently downgraded, regardless of rating levels. Interestingly, this holds during and after the GFC, but not before. We offer two implications. First, despite post-GFC outcry against the CDS market, our results suggest it exhibits enhanced price discovery during the GFC. Second, our findings support criticism that, in the lead-up to the GFC, rating agencies are slow in downgrading firms. However, if downgrade decisions made during and after the GFC induce informed trading in the CDS market, this necessarily implies that during the midst of the GFC, rating agencies have got their act together.

Analysis of insiders attack mitigation strategies

Insider threat has become a serious information security issues within organizations. In this paper, we analyze the problem of insider threats with emphases on the Cloud computing platform. Security is one of the major anxieties when planning to adopt the Cloud. This paper will contribute towards the conception of mitigation strategies that can be relied on to solve the malicious insider threats. While Cloud computing relieves organizations from the burden of the data management and storage costs, security in general and the malicious insider threats in particular is the main concern in cloud environments. We will analyses the existing mitigation strategies to reduce malicious insiders threats in Cloud computing.
