Information Security Risk

With the development of society, we have entered the information age.Computer network technology is widely used in people’s life and production, and has played an important role in promoting social progress. However, due to its own nature and characteristics, some security risks have appeared in the process of application in the development of computer network technology, which interferes with the safe use of computer networks. This article combines the information security risk of computer network, making an analysis of the information security architecture of computer network based on WPDRRC model, and the strategy of how to prevent computer network security risk.

Security Risk Management

One of the key requirements for the protection of an organization's information assets is to ensure proper information security risk management. In the process of risk management, they should be identified, assessed, analyzed and processed in order to change the value of risk to an acceptable level. The article proposes to consider ways to reduce information risks that may be caused by critical categories of threats and vulnerabilities.

Information Security Risk

This paper developed a method to assess information security risks in e-healthcare. Specifically, it first developed a static E-Healthcare Information Security Risk (EHISR) model to present thirty-three security risk factors by identifying information security threats and their sources in e-healthcare. Second, a dynamic E-Healthcare Information Flow (EHIF) model was developed to logically link these information risk factors in the EHISR model. Pattern analysis showed that information security risks could be classified into two levels, and versatility analysis showed that the overall security risks for eight information flows were close with a range from 55% to 86%. Third, one quantifiable approach based on a relative-weighted assessment model was developed to demonstrate how to assess the information security risks in e-healthcare. This quantitative security risk measurement establishes a reference point for assessing e-healthcare security risks and assists managers in selecting a reliable information flow infrastructure with a lower security risk level.

Contemporary methods for assessing information security risks have adopted mainly technical views on information and technology assets. Organizational dynamics of information management and knowledge sharing have gained less attention. This article outlines a new, genre-based, approach to information security risk assessment in order to orientate toward organization- and knowledge-centric identification and analysis of security risks. In order to operationalize the genre-based approach, we suggest the use of a genre-based analytical method for identifying organizational communication patterns through which organizational knowledge is shared. The genre-based method is then complemented with tasks and techniques from a textbook risk assessment method (OCTAVE Allegro). We discuss the initial experiences of three experienced information security professionals who tested the method. The article concludes with implications of the genre-based approach to analyzing information and knowledge security risks for future research and practice.

Abstract To assess and prevent the smart grid information security risks more effectively, this paper provides risk index quantitative calculation method based on absorbing Markov chain to overcome the deficiencies that links between system components were not taken into consideration and studies mostly were limited to static evaluation. The method avoids the shortcomings of traditional Expert Score with significant subjective factors and also considers the links between information system components, which make the risk index system closer to the reality. Then, a smart grid information security risk assessment model on the basis of set pair analysis improved by Markov chain was established. Using the identity, discrepancy, and contradiction of connection degree to dynamically reflect the trend of smart grid information security risk and combining with the Markov chain to calculate connection degree of the next period, the model implemented the smart grid information security risk assessment comprehensively and dynamically. Finally, this paper proves that the established model is scientific, effective, and feasible to dynamically evaluate the smart grid information security risks.

Information security risk assessment is an important part of enterprises’ management practices that helps to identify, quantify, and prioritize risks against criteria for risk acceptance and objectives relevant to the organization. Risk management refers to a process that consists of identification, management, and elimination or reduction of the likelihood of events that can negatively affect the resources of the information system to reduce security risks that potentially have the ability to affect the information system, subject to an acceptable cost of protection means that contain a risk analysis, analysis of the “cost-effectiveness” parameter, and selection, construction, and testing of the security subsystem, as well as the study of all aspects of security.

Informationization and automation are important in library management due to the development of computer technology and network technology. Although computer networks bring great convenience and improvement to library management’s efficiency and quality, there are many security issues that could tag along with networks. The library information is prone to leak due to virus and hackers as well as the transparency of the network. Thus, this leads to a high security risk in library management. Therefore, this paper mainly analyses the security management strategies of library computer networks.
