A Theory on Information Security
Australasian Conference on Information Systems Horne et al. 2016, Wollongong, Australia A Theory on Information Security A Theory on Information Security Craig A. Horne Department of Computing and Information Systems The University of Melbourne Victoria, Australia Email: [email protected] Atif Ahmad Department of Computing and Information Systems The University of Melbourne Victoria, Australia Email: [email protected] Sean B. Maynard Department of Computing and Information Systems The University of Melbourne Victoria, Australia Email: [email protected] Abstract This paper proposes a theory on information security. We argue that information security is imperfectly understood and aim to bring about an altered understanding of why efforts are made to engage in information security. The goal of information security is widely recognised as the confidentiality, integrity and availability of information however we argue that the goal is actually to simply create resources. This paper responds to calls for more theory in information systems, places the discussion in philosophical context and compares various definitions. It then identifies the key concepts of information security, describes the relationships between these concepts, as well as scope and causal explanations. The paper provides the theoretical base for understanding why information is protected, in addition to theoretical and practical implications and suggestions for future research. Keywords Information security, resources, controls, threats, theory development. 1 Australasian Conference on Information Systems Horne et al. 2016, Wollongong, Australia A Theory on Information Security 1 INTRODUCTION Despite the concept of information security being very well established, the reasons and motivations behind it are imperfectly understood. This paper seeks to explain how and why the phenomena that comprise the concepts of information security occur. -
Information Security Essentials Definition of Information Security
Computing Services Information Security Office Information Security Essentials Definition of Information Security Information security is the protection of information and systems from unauthorized access, disclosure, modification, destruction or disruption. The three objectives of information security are: • Confidentiality • Integrity • Availability Confidentiality Confidentiality refers to the protection of information from unauthorized access or disclosure. Ensuring confidentiality is ensuring that those who are authorized to access information are able to do so and those who are not authorized are prevented from doing so. Integrity Integrity refers to the protection of information from unauthorized modification or destruction. Ensuring integrity is ensuring that information and information systems are accurate, complete and uncorrupted. Availability Availability refers to the protection of information and information systems from unauthorized disruption. Ensuring availability is ensuring timely and reliable access to and use of information and information systems. Information Security Policy Carnegie Mellon has adopted an Information Security Policy as a measure to protect the confidentiality, integrity and availability of institutional data as well as any information systems that store, process or transmit institutional data. Institutional data is defined as any data that is owned or licensed by the university. Information system is defined as any electronic system that stores, processes or transmits information. Policies • Throughout its lifecycle, all Institutional Data shall be protected in a manner that is considered reasonable and appropriate given the level of sensitivity, value and criticality that the Institutional Data has to the University. • Any Information System that stores, processes or transmits Institutional Data shall be secured in a manner that is considered reasonable and appropriate given the level of sensitivity, value and criticality that the Institutional Data has to the University. -

Understanding Holistic Database Security 8 Steps to Successfully Securing Enterprise Data Sources 2 Understanding Holistic Database Security
Information Management White Paper Understanding holistic database security 8 steps to successfully securing enterprise data sources 2 Understanding holistic database security News headlines about the increasing frequency of stolen information and identity theft have focused awareness on data security breaches—and their consequences. In response to this issue, regulations have been enacted around the world. Although the specifics of the regulations may differ, failure to ensure compliance can result in significant financial penalties, loss of customer loyalty and even criminal prosecution. In addition to the growing number of compliance mandates, organizations are under pressure to embrace the new era of computing, which brings with it new security challenges and a complex security landscape. Hackers are becoming more skilled; they are building sophisticated networks and in some cases are state sponsored. The rise of social media, cloud computing, mobility and big data are making threats harder to identify. Thus unscrupulous insiders are finding more ways to pass protected information to outsiders with less chance of detection. Organizations need to adopt a more proactive and Figure 1: Analysis of malicious or criminal attacks experienced according to systematic approach to securing sensitive data and addressing the 2011 Cost of Data Breach Study, Ponemon Institute published March 2012 compliance requirements amid the digital information explosion.

Vol. 7, No. 3, 2019, pp. 82-86. doi: 10.11648/j.jeee.20190703.12 Received : August 18, 2019; Accepted : September 21, 2019; Published : October 9, 2019 Abstract: The author describes computing strategic tasks that are used for ensuring defense and national security, the most important scientific, technical, biomedical and sociology tasks. Most typically, these are capability-based tasks. Supercomputers for their solution are respectively called Technical Capability, i.e. machines of extreme technical capabilities. Machines of this segment are also called High End Computers (HEC), and in our terminology - strategic supercomputers (SCs). Moving to the engineering level, author says that for tasks with good spatio-temporal work with memory, cache memory and schemes for automatically pre-loading data into the cache memory can be effectively used. This can significantly reduce the average memory access time of several hundred processor cycles to fractions of a processor cycle. Such tasks are usually called computational or cache-friendly (cach-friendly) - CF tasks. On tasks with poor spatio-temporal work with memory, the cache memory is useless, so each memory access is hundreds of processor cycles, the processor is idle because of this, and therefore the real performance is in units or even a fraction of a percent of the peak. -
