Towards a framework to ensure alignment among information security professionals, ICT security auditors and regulatory officials in implementing information security in South Africa

Basani, Mandla 02 1900 (has links)
Information security in the form of IT governance is part of corporate governance. Corporate governance requires that structures and processes are in place with appropriate checks and balances to enable directors to discharge their responsibilities. Accordingly, information security must be treated in the same way as all the other components of corporate governance. This includes making information security a core part of executive and board responsibilities. Critically, corporate governance requires proper checks and balances to be established in an organisation; consequently, these must be in place for all information security implementations. In order to achieve this, it is important to have the involvement of three key role players, namely information security professionals, ICT security auditors and regulatory officials (from now on these will be referred to collectively as the ‘role players’). These three role players must ensure that any information security controls implemented are properly checked and evaluated against the organisation’s strategic objectives and regulatory requirements. While maintaining their individual independence, the three role players must work together to achieve their individual goals with a view to, as a collective, contributing positively to the overall information security of an organisation. Working together requires that each role player must clearly understand its individual role, as well the role of the other players at different points in an information security programme. In a nutshell, the role players must be aligned such that their involvement will deliver maximum value to the organisation. This alignment must be based on a common framework which is understood and accepted by all three role players. This study proposes a South African Information Security Alignment (SAISA) framework to ensure the alignment of the role players in the implementation and evaluation of information security controls. The structure of the SAISA framework is based on that of the COBIT 4.1 (Control Objectives for Information and Related Technology). Hence, the SAISA framework comprises four domains, namely, Plan and Organise Information Security (PO-IS), Acquire and Implement Information Security (AI-IS), Deliver and Support Information Security (DS-IS) and Monitor and Evaluate Information Security (ME-IS). The SAISA framework brings together the three role players with a view to assisting them to understand their respective roles, as well as those of the other role players, as they implement and evaluate information security controls. The framework is intended to improve cooperation among the role players by ensuring that they view each other as partners in this process. Through the life cycle structure it adopts, the SAISA framework provides an effective and efficient tool for rolling out an information security programme in an organisation / Computer Science / M.

A risk based approach for managing information technology security risk within a dynamic environment

Mahopo, Ntombizodwa Bessy 11 1900 (has links)
Information technology (IT) security, which is concerned with protecting the confidentiality, integrity and availability of information technology assets, inherently possesses a significant amount of known and unknown risks. The need to manage IT security risk is regarded as an important aspect in the daily operations within organisations. IT security risk management has gained considerable attention over the past decade due to the collapse of some large organisations in the world. Previous investigative research in the field of IT security has indicated that despite the efforts that organisations use to reduce IT security risks, the trend of IT security attacks is still increasing. One of the contributing factors to poor management of IT security risk is attributed to the fact that IT security risk management is often left to the technical security technologists who do not necessarily employ formal risk management tools and reasoning. For this reason, organisations find themselves in a position where they do not have the correct approach to identify, assess and treat IT security risks. The IT security discipline is complex in nature and requires specialised skills. Organisations generally struggle to find a combination of IT security and risk management skills in corporate markets. The scarcity of skills leaves organisations with either IT security technologists who do not apply risk management principles to manage IT security risk or risk management specialists who do not understand IT security in order to manage IT security risk. Furthermore, IT is dynamic in nature and introduces new threats and vulnerabilities as it evolves. Taking a look at the development of personal computers over the past 20 years is indicative of how change has been constant in this field, from big desktop computers to small mobile computing devices found today. The requirement to protect IT against threats associated with desktops was far less than the requirement associated with protecting mobile devices. There is pressure for organisations to ensure that they stay abreast with the current technology and associated risks. Failure to understand and manage IT security risk is often cited as a major cause of concern within most organisations’ IT environments because comprehensive approaches to identify, assess and treat IT security risk are not consistently applied. This is due to the fact that the trend of IT security attacks across the globe is on the increase, resulting in gaps when managing IT security risk. Employing a formal risk based approach in managing IT security risk ensures that risks of importance to an organisation are accounted for and receive the correct level of attention. Defining an approach of how IT security risk is managed should be seen as a fundamental task and is the basis of this research. This study aims to contribute to the field of IT security by developing an approach that assists organisations in treating IT security risk more effectively. This is achieved through the use of a combination of existing best practice IT security frameworks and standards principles, basic risk management principles, as well as existing threat modelling processes. The approach developed in this study serves to encourage formal IT security risk management practices within organisations to ensure that IT security risk is accounted for by senior leadership. Furthermore, the approach is anticipated to be more proactive and iterative in nature to ensure that external factors that influence the increasing trend of IT security threats within the IT environment are acknowledged by organisations as technology evolves. / Computing / M.

Integration of information management systems to enhance business intelligence at the Department of Transport in South Africa

Chauke, Tshepo 02 1900 (has links)
Public sector decision makers are confronted by pressures to make faster and better decisions as a result of the competitive environment they operate in. However, there is a trend in the public sector, including the Department of Transport (DoT) in South Africa, to invest in management information systems (MIS) that are highly fragmented and not aiding effective and timely decision-making. As a result, the country witnessed several service delivery protests since 2008 which also affected the public transport sector, such as the widespread burning of Metrorail trains several times by angry commuters. In most instances, poor service delivery emanates from the fact that public servants do not have information at their fingertips to make decisions. This quantitative study utilised Control Objectives for Information and Related Technologies 5 (COBIT 5) as a theoretical framework to investigate the integration of MIS at the DoT with a view to enhancing business intelligence for effective decision-making. Data were collected through a questionnaire directed at middle managers and senior managers that were selected through stratification of business units at the DoT, as well as analysis of documents such as system specifications and strategic plans. The study established that the DoT has several systems such as Alfresco, BAS, GIS, Logis and Persal to name a few, which serve different purposes. However, in most instances, the systems are not integrated as the current infrastructure did not support integration needs and plans to accommodate changing requirements. This is compounded by the system policy implementation constraints, as well as ageing legacy systems that are obsolete. The only component where MIS was found to be integrated, was in the financial business units (Supply Chain Management, Finance and Budgeting). Core business units use off-the-shelf systems and, in some cases, custom-made applications that do not integrate with any other system and thus hinder decision-making. In conclusion, decisions are made based on thumb-sucking, as management does not have access to comprehensive information that is stored in fragmented unintegrated systems. The study recommends that governance structures should be set up to deal with a more holistic business, information and technology architecture for the DoT that enable integration of various systems for effective decision-making. Failure to transform this pattern would lead to service delivery protests persisting. A further study on a framework to integrate MIS in the public sector is recommended. / Information Science / M.

Addressing the incremental risks associated with adopting a Bring Your Own Device program by using the COBIT 5 framework to identify keycontrols

Weber, Lyle 04 1900 (has links)
Thesis (MComm)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: Bring Your Own Device (BYOD) is a technological trend which individuals of all ages are embracing. BYOD involves an employee of an organisation using their own mobile devices to access their organisations network. Several incremental risks will arise as a result of adoption of a BYOD program by an organisation. The research aims to assist organisations to identify what incremental risks they could potentially encounter if they adopt a BYOD program and how they can use a framework like COBIT 5 in order to reduce the incremental risks to an acceptable level. By means of an extensive literature review the study revealed 50 incremental risks which arise as a result of the adoption of a BYOD program. COBIT 5 was identified as the most appropriate framework which could be used to map the incremental risks against. Possible safeguards were identified from the mapping process which would reduce the incremental risks to an acceptable level. It was identified that 13 of the 37 COBIT 5 processes were applicable for the study.
