At the opposite end side of the spectrum are people who may compromise the IS accidentally. Hackers range from inexperienced professional, college student, or novice (e.g., script kiddy) to the highly technical and capable. Most hackers pride themselves on their skill and seek, not to destroy, but simply to gain access so that the computer or network can be used for later experimentation. Hackers often believe that by exposing a hole or 'back-door' in a computer system, they are actually helping the organization to close the holes, providing a benefit to the Internet and a needed resource. Other hackers have less benign motives for getting inside.

Information security risk management for computerized health information systems in hospitals: a case study of Iran

Information security risk management for computerized health information systems in hospitals: a case study of Iran

In the third step, based on results of the previous stage, health information management and computer experts’ opin- ions, and observations of the five selected hospitals, a com- prehensive form was designed to assess the status of ISRM for computerized health information systems, including four dis- tinct parts encompassing general information about hospitals, specifications of computerized health information systems, information security incidences, and self-assessment checklist of ISRM. Its content validity was confirmed by 12 experts of health information management, medical informatics, information technology (IT), and computer engineering (three professionals per area of study).These scholars were selected on the basis of their previous work experience in the hospital’s IT departments or their familiarity with the structure of the IT department in the hospitals of Iran. For data collection, this questionnaire and its guideline were sent to all 908 active hospitals in Iran by the Ministry of Health of Iran. To remove any possible ambiguity, an instruction sheet was attached to this questionnaire, explaining all sections. The hospitals were selected with regard to their CHIS application, such as hospi- tal information system, Electronic Medical Record, Patient’s Admission and Discharge Systems, and so on. Hospitals that did not use CHIS at the time of this research were excluded. To facilitate and expedite the collection of data, this form was placed electronically in the official Web site (portal) of the Ministry of Health of Iran and hospitals were asked to register the relevant information in the aforementioned Web site.

Information security risk management in a public institution: a case study

Information security risk management in a public institution: a case study

Electronic information used by companies constantly increases, while its management, ease of access, adequacy, reliability and compliance tends to be even more complex in order to meet organizational objectives. In addition, organizations are concerned about exposure caused by incidents that could compromise their activities (Posthumus and Von Solms, 2004).Influenced by needs, goals, security requirements, processes, size and structure, organizations tend to specify and strategically implement an Information Security Management System (ISMS) that meets organization's objectives. In its latest update, ISO/IEC 27001:2013 standardizes definitions and structures of different ISO standards in order to provide an even more effective risk management by including requirements to assess and treat information security risks (ISO/IEC 27001, 2013). Nevertheless, a continuous improvement approach through a process of creating, implementing, operating, monitoring, reviewing, maintaining and improving the organization's ISMS adopts the Plan-Do-Check-Act (PDCA) cycle while taking into account security requirements of information and actions required to meet stakeholder's expectations. The model reflects, among others, the principles of governance of information systems and networks, risk analysis, specification, implementation, administration and security revaluation (Da Veiga and Eloff, 2007; ISO/IEC 27001, 2005; ISACA, 2012). Information privacy and security are concepts related to protection and both should be considered when dealing with

Information Security Management System Standards: A Comparative Study of the Big Five

Information Security Management System Standards: A Comparative Study of the Big Five

Information is the lifeblood of organizations, a vital business asset in today’s Information Technology (IT) -enabled world. Access to high-quality, complete, accurate and up-to- date information is vital in supporting managerial decision- making process that leads to sound decisions. Thus, securing information system resources is extremely important to ensure that the resources are well protected. Information security is not just a simple matter of having usernames and passwords [5]. Regulations and various privacy / data protection policy impose a raft of obligations to organizations [6]. Meanwhile viruses, worms, hackers, phishers and social engineers threaten organizations on all sides. Hackers or sometimes we call edit by unidentified user is likely to cause huge losses for an organization [figure 1], such as by theft of customer data, spy on business strategy, for the benefit of competitors [7]. It is imperative for organizations to use an information security management system (ISMS) to effectively manage their information assets. ISMS is basically consist of sets of policies put place by an organization to define, construct, develop and maintain security of their computer based on hardware and software resources. These policies dictate the way in which computer resources can be used.

A Risk Driven Investment Model for Analysing Human Factors in Information Security

A Risk Driven Investment Model for Analysing Human Factors in Information Security

Technical advancements do not always produce a more secure environment. All kinds of human factors can deeply affect the management of security in an organisational context; therefore, security is not solely a technical problem; rather, we need to understand human factors to achieve effective information security system practice. For this purpose, the study identifies critical direct and indirect human factors that impact upon ISSs. These factors were analysed through the study of two security incidents in UK financial organisations using the SWOT (Strength, Weaknesses, Opportunities, and Threats) technique discussed in the preceding chapter. Typically, human work within an organisation falls into four categories: individual, team, management and customer/interested party [83] [31]. Human factors within these categories can become uncontrollable forces. Because people have different perceptions of security, their reactions to information security procedures are diverse. Each individual has concerns, values, culture, skills, knowledge, attitudes and behaviour of his or her own. These factors are highly subjective and extremely hard to measure and calculate in ISS processes. These human forces interact with technological elements in an interconnected world of so-called “secure information systems” [32]. People have their own unique culture, attitudes, skills, knowledge, understandings, behaviour and interests that depend upon the role that they play within the organisation. Individuals’ interaction with computers and decisions made with regard to information security are certainly very dynamic and complex issues. Human factors are the greatest single issue of concern in IS [33]. We therefore need a comprehensive understanding of human factors and their impacts for an effective implementation of ISSs. This task is challenging, as the domain is highly subjective by nature and it is difficult to quantify all the factors into a measuring scale. There are many areas in which judgement becomes extremely difficult and hugely subjective because the study is about people and their reactions to IS and, therefore, it is highly personal. For instance, it would be extremely difficult to judge and evaluate people’s apathy and their attitudes towards ISSs.

A Mobile Agent Model For Management Information System

A Mobile Agent Model For Management Information System

Abstract: Management Information Systems represent a managerial approach to information systems concepts and applications. Computers have become pervasive in every aspect of our lives. Mobile agent paradigm is an emerging and exciting paradigm for Management Information System. Reasons are the inefficiencies associated with more traditionally distributed systems such as client-server applications in terms of latency, bandwidth, vulnerability to network disconnection, mobility etc. The main problems like scaling, integrating and staffing (security expert) are expected of this study to decrease. The study aims to develop Mobile Agent for MIS for quick and adequate operation enhancement. Mobile agent technology helps design wide range of adaptive, flexible applications with non -permanent connections by adding mobility to code, machine based intelligence, improved network and database possibilities. The adoption of Mobile Agent System Model in this study has shown the strength of an agent on information retrieval. Apart from these, the Mobility of Mobile Agent Architecture has been used as a concept for searching and retrieving information among categorized MIS databases available on a network. The system was designed using JAVA as its frontend and MySQL which is the control and management of the data call for database management system (DBMS) which also handle structured data that will store information submitted as its backend. This language was chosen because of its wealth of compatibilities and features for developing applications. Regardless of the available tools, management information system with mobile agent is a system that will enhance better achievement of result.

Managing Social Security Data in the Web 2 0 Era

Managing Social Security Data in the Web 2 0 Era

Social security data management is an important topic both in application of information management and in social se- curity management. In the Web 2.0 era, more and more human information and healthcare information is released to the Internet through various approaches. This abundance makes managing social security data go beyond managing con- ventional social security database records. How to organize the conventional records together with the related informa- tion gathered from the Web is an interesting problem to solve to provide more convenient and powerful social security information service. In this paper, we introduce our initial work on building a Web-oriented social security information system named i-SSIS. I-SSIS is a database system which adopts a new object-role data model named INM model and deploys INM database system as its core. With the assistance of auxiliary tools to carry out social security information extraction, analyzing and query, i-SSIS can properly provide social security-related information gathered from the Web. We introduce the basic ideas of designing i-SSIS and describe the architecture and major components of the system.

A Reformed Information Security Management System (R ISMS)

A Reformed Information Security Management System (R ISMS)

Today’s information systems are complex collections of technology (i.e., hardware, software, and firmware), processes, and people, working together to provide organizations with the capability to process, store, and transmit information in a timely manner to support various missions and business functions. Information needs to be available, accurate and up-to-date to enable an organization make good business decisions. While various ISMS frameworks have been implemented and adopted by organizations, the focus has been more on the use of technology as a means of securing information systems. However, information security needs to become an organisation-wide and strategic issue, taking it out of the IT domain and aligning it with the corporate governance approach. Furthermore, an algorithm-based ISMS model demonstrating Information Technology General Controls (ITGC) concepts, is proposed with a more human-centred

Information Security System and Its Different Techniques

Information Security System and Its Different Techniques

Qualitative: It involves the assessment of the effects of identified risk factors and the creation of priorities that can be used to decide on how to solve the potential risk factors. They are simple and hence are considered better than quantitative method as the risks are expressed in terms of descriptive variables. They are based on judgment and intuition. They are complex and pose serious problems in secondary schools due to complexities. Ex: Hazard and Operability study (HAZOP), Failure Mode and Effects Analysis (FMEA) and CCTA-Risk Analysis and Management Method (CRAMM). Not all techniques require strong expertise or are complex. Technique like OCTAVE (Operationally Critical Threat, Asset and Vulnerability Evaluation) which is a layered based technique provides easy, cheap and viable means of achieving the same objectives. It has also been found to be the most appropriate one as not much knowledge is required in the field of information risk management. Hence OCTAVE is always recommended for small scale organizations.

organization Gartner as: The information assets need new processing mode to have the greater deci- sion-making power, insight discovery and process optimization of massive, high growth rate and diversi- fication. From the data category, the big data refers to the information which can’t be dealt with by using traditional processes or tools. The definition of big data is defined by Wikipedia as: A collection of data can’t be captured, managed, and processed with con- ventional software tools in the affordable time range. Big data has four features: Volume, Velocity, Variety and Value. ĸ The features of big data are also reflected in two aspects, one is the data volume that grows in a geometric level, and the other is that the data source is very abundant. The proportion of non-structured data increases more and more. The security industry has begun to shift to the cloud with the widespread big data and cloud services, because the traditional secu- rity system, which can’t effectively and quickly find unknown threats, has been very weak or disintegrated to the role of big data and cloud platform.

Testing and bug fixing of the information security management system

Testing and bug fixing of the information security management system

Development of the Information Security Management System (ISMS software) has been started since 2008 at SCAN. Because, ISMS had initially been developed for governmental organization, therefore delivering a quality product has been important for the company. Moreover, as one of its obligations the company should service its clients according to the CMMI level 3 standard. In addition to the above, SCAN should support the ISMS client (the government) with the newer versions. Therefore, in order to maintain the quality of the software, the ISMS must be delivered with the least possible problems. One of the solutions to this problem is to frequently test the software and fix the problems for every new version that is going to be released.

Optimization Methodology for Change Management Controls Using Grey Systems Theory

Optimization Methodology for Change Management Controls Using Grey Systems Theory

In Otero, Otero, and Qureshi (2010), innovative control evaluation and selection approach were developed, particularly for information security controls, to help decision makers select the most effective ones in resource- constrained environments. The approach used desirability functions to quantify the desirability of each security control after taking into account the benefits and restrictions associated with implementing the particular control. The above-provided management with a measurement that was representative of the overall quality of each security control based on organizational goals. Through a case study, the approach proved successful in providing a way for measuring the quality of security control in organizations. Otero et al.’s (2010) methodology took into consideration relevant quality attributes of each security control in order to determine their relative importance. This allowed a control selection scheme that represented how well these security control met quality attributes, and how important those quality attributes were for the specific organization. The quality attributes were defined in terms of different features, where each feature was determined by the organization to either be present or not. Once all features were identified, each individual security control was evaluated against each feature using a simple binary (boolean) scale (0 or 1). Security controls that satisfied the highest number of features exposed a higher level of quality (or priority) for that particular quality attribute. The above resulted in a control evaluation approach based on how well security controls met quality attributes, and how important those quality attributes were for the organization. However, boolean criteria for evaluating the quality attributes of each security control in order to ultimately determine which ones to select, may not be considered a precise enough assessment for selecting and ultimately implementing security controls in organizations.

THE NEED FOR ESTABLISHMENT OF PROFESSION “DESIGNER OF INTEGRATED SECURITY MANAGEMENT SYSTEM”

THE NEED FOR ESTABLISHMENT OF PROFESSION “DESIGNER OF INTEGRATED SECURITY MANAGEMENT SYSTEM”

However, the inclusion of those subjects or of a part thereof in training of professionals is not sufficient. This approach includes only the organizational part (see the beginning of this article) in the construction of integrated security systems. What about the training of professionals capable of developing the technical part and writing procedures for the implementation of each of the activities related to security and defense? As already mentioned, not all of the team to build the system can know everything, for this purpose there are specialists in different disciplines and subsystems of the management system of the organization. But I think two people should have at least general knowledge of all subjects relating to the provision of security and protection of critical infrastructure. This is the Designer of Integrated Security Management System and Security Project Manager. Both should make sure you have knowledge and experience in the establishment of the organizational part of the system. As for the technical part, the Designer must master, above all, the specificity of information technology, while the Project Manager needs to know how they should be managed for security purposes (IT are at the heart of building security systems). Someone will say that for that purpose, system administrators or engineers in the IT area. This will answer that "narrow" IT professionals should always have corrective in the face of security specialists, the latter is necessary to master the basic principles in the IT area. This is a must if we don’t want IT specialists always to offer us for building security systems to buy the most expensive "toys" in their area (this is the mentality of most of his colleagues who really deep knowledge in IT area). Namely security specialists must have the ability to make accurate analysis of cost-benefit and build security levels of the organization, taking into account its specific needs in this area. And such a security expert in this case must be the Designer, which laid the foundations of the security system.
