Introduction
Information systems are now heavily utilized by all organizations and relied upon to the extent that it would be impossible to manage without them. This has been encapsulated by the recent development of e-commerce in a consumer and business environment. The situation now arises that information systems are at threat from a number of security risks and what is needed is a security method to allow for these risks to be evaluated and ensure that appropriate security countermeasures are applied.

Abstract

E-commerce security is a complex issue; it is concerned with a number of security risks that can appear at either a technical level or organisational level. This paper uses a systemic framework, the viable system model (VSM) to determine the high level security risks and then uses baseline security methods to determine the lower level security risks.

Security methods
The aim of the research was too combine a information systems modeling method with a baseline security method to form a hybrid security method. This method could be used to evaluate high and low level security risks associated with e-commerce. The methods used in this model are the viable system model (VSM) and baseline security approach. The VSM is used to model an organisation's basic functions and associated data flows, whilst the baseline security approach is used to implement appropriate security countermeasures.

The viable system model (VSM)

...information security and for managing information system-related security risks (National Institute of Standards and Technology, 2010). One common methodology for implementing information security is known as Certification and Accreditation. Certification and Accreditation is a process that ensures that systems and major applications adhere to formal and established security requirements that are well documented and authorized (Tipton & Krause, 2007). In order to improve information security, strengthen risk management processes, guarantee standardization, and enforce federal policies, the National Institute of Standards and Technology (NIST) partnered with the Department of Defense to transform the traditional Certification and Accreditation (C&A) process into the six-step Risk Management Framework (RMF) (National Institute of Standards and Technology, 2010). The Risk Management Framework provides a structured, yet flexible approach for managing risk to the business processes of a federal organization; however, these principles are crucial to both federal and commercial IT operations since they certify that the management of security risks is consistent with the organization’s mission objectives. Additionally, they ensure the risk management framework is smoothly integrated into the organization’s enterprise architecture (NSIT, 2010). Risk Management Framework The following steps identify the six steps encompassed in the RMF and define the approach required......

...Therefore, a proper understanding of risk management and all that it entails is of the utmost importance for every IT professional, regardless of specialization. The purpose of this paper is to identify what risk management is and give an overview of the three phases or undertakings that make up the risk management process and then conclude with a discussion and explanation of the six-step Risk Management Framework (RMF) developed by the Department of Defense and the National Institute of Standards and Technology (NIST) (National Institute of Standards and Technology, 2010). “Risk management is the process of Identifying risks, as represented by vulnerabilities, to an organization’s information assets and infrastructure, and taking steps to reduce this risk to an acceptable level” (Michael E. Whitman, Herbert J. Mattord, 2012, p. 119.). Thus, risk management is merely the ability of a person or organization to implement due diligence and identify any potential issue and develop policies and security measures to combat these risks. Risk management is comprised of three phases: risk identification, risk assessment, and risk control (Michael E. Whitman, Herbert J. Mattord, 2012, p. 119.). Risk Identification Risk identification is simply the identification and documentation of the assets and the threats to those assets. Risk identification is an iterative process that consists of six steps: the planning and organization of the risk management process, categorize the......

Security and Risk Management

...operations are filled with risk. On a personal level we take risks crossing the road, travelling by train and making investment decisions. From a business perspective, risk is managed at many levels - operational, marketing, legal and financial. Traditionally, much risk inherent in a business operation has been managed through insurance. In reality, we are all aware that risk can no longer be managed on an ad hoc basis, but should be sewn into the fabric of corporate management. In other words, an organization will not be able to make strategic choices to maximise performance without having a clear understanding of the risk it faces. People make risk decisions at all levels in an organization, ranging from individual responsibilities to collective decisions made at Board level. Allowing individuals too much autonomy within an organisation can have disastrous consequences. Consequently, compliance and adherence to regulations is important to all risk management programmes, which in turn have focused organisations on corporate governance as a form of management control. Risk analysis helps put in place checks and procedures that reduce the chance of negative outcomes. In relation to the risk management situation, we can always relate to Nick Leeson's case, who had lost Baring’s Bank $1.3 billion on trading derivatives, destroying Barings and its reputation within a short period of time. Inter-related Crisis and Risk management Crisis and Risk management are two......

A periodic review of the E-Security framework, in light of the quickly evolving threat landscape, is both timely and appropriate. Over the last thirty years there have been dramatic advances in information technology - the development of the microprocessor, the rise of the personal computer, the emergence of the Internet - which have revolutionised the way information is created, stored, shared, and used. Today, powerful, affordable and diverse devices, together with expanding broadband networks, create a powerful opportunity for connectivity for individuals and communities. Over the past two decades, rapid advances in software, IT services, and communications have enabled many traditionally separate and disparate infrastructures and business operations to become more connected. Through this connectivity virtually every aspect of society has experienced a transformation. Businesses and governments have been able to manage and streamline their operations. Individuals have been offered ready access to multiple sources of information thereby expanding knowledge and choice. Across every field of endeavour – commercial, social, scientific and philanthropic – the power of information has been increased and the transaction costs of engagement have been lowered.
