Design of network information visualization security cognition system based on QSOFM network and FR algorithm

ABSTRACT Network information is complex, there is no lack of hidden risks of information to the user caused by bad effects. But analyzing and evaluating them is complex and requires more diverse and powerful techniques. This research will combine Fruchterman-Reingold (FR) information visualization algorithm and information security risk assessment method based on Quantum self-organizing feature map (QSOFM) network to build information visualization security cognitive system. By introducing quantum neurons into self-organizing feature mapping network (SOFM), a network information security evaluation model is constructed. The system can evaluate the security level of network information and visualize the evaluation results. The experimental results show that the system has fast response speed and strong interactivity. The accuracy of QSOFM algorithm is 86%, 12% higher than the traditional algorithm, which can provide more powerful technical support for the visual security cognition of network information.

According to this method, this paper analyzed 25 smart cities in China, and provided suggestions and guidance for information security control in the process of urban informatization construction.

Research on Information Security Risk Analysis and Prevention Technology of Network Communication Based on Cloud Computing Algorithm

Data communication network must use telephone, cable or optical fiber as transmission medium and computer as information receiving, output and communication tool. Customers can not only process the received information, but also realize information sharing through the network. With the wide application of network communication in daily life, network security issues have higher requirements. In order to solve the problems of subjectivity, long modeling time and low classification accuracy of information security risk assessment methods, this paper first proposes an intelligent information security risk assessment method based on decision tree. Compared with other classification algorithms such as support vector machine, the decision tree classification algorithm has no requirement for data category distribution, and has good classification effect and fast speed. Finally, this paper introduces the security measures in network data communication for reference only.

An analysis of methods for assessing information security risks of financial institutions

The paper presents an analysis of the existing methods for assessing information security risks, their features, advantages and disadvantages, as well as determines the possibility of using such techniques for assessing information security risks in financial institutions. Criteria for comparing information security risk assessment methods have been formed, the advantages and disadvantages of the methods are described. It is shown that, despite the requirements of regulators for assessing information security risks, most of the regulatory documents deal with operational risks. The evaluation of information security risks of credit and financial institutions does not have sufficient regulation and formalization.The authors substantiate the necessity of developing a method for assessing information security risks for credit and financial organizations, taking into account the features of risk assessment inherent to the mentioned organizations. The paper considers the need to create lists of existing threats to the credit and financial sector and their linking to existing vulnerabilities to optimize the process of assessing information security risks. The development of a methodology for assessing information security risks will increase the degree of compliance of credit and financial institutions with the requirements of international, state and industry standards through an optimal set of protection measures and models for evaluating information security risks.

Research on Information Security Risk Assessment Method Based on Fuzzy Rule Set

With the increasing complexity of the network structure and the increasing size of the network, various network security incidents pose an increasing threat to the security of computer systems and the network. Especially, in the network environment, the diversified intrusion methods and application environment make the security of the network more fragile. In order to improve information security, based on fuzzy rule sets, this paper proposes a fuzzy association rule mining algorithm based on fuzzy matrix and applies it to security event correlation. In addition, this paper combines the embedded system to construct an information security risk assessment system and sets the system performance based on the actual situation. Finally, this paper carries out experimental design to verify the performance of the system and analyzes the experimental results by mathematical statistics. From the experimental research, it can be seen that the system constructed in this paper has a certain effect.

Combination of D-AHP and Grey Theory for the Assessment of the Information Security Risks of Smart Grids

As a modern power infrastructure, smart grids have great advantages over traditional power grids, but their effective operation is largely restricted by information security. Hence, a smart grid information security risk assessment (ISRA) method is proposed. This method combines D numbers to improve the classical analytic hierarchy process (D-AHP) independent of experts’ subjective qualitative assessment and then integrated with grey theory which does not require complete and unambiguous information. First, we establish a smart grid ISRA system according to the characteristics and development reality of smart grid technology. The proposed system includes 5 first-level indexes as an intelligent terminal, a wireless communication channel, password security, application code and embedded system, and corresponding 13 secondary indexes. Second, a D-AHP method aimed at the uncertainty of human subjective judgment and fuzziness of language assessment is used to obtain the weight of each index. The D-AHP method is then combined with the grey assessment matrix solved by grey theory, to obtain the comprehensive assessment value and corresponding risk grade. With a smart grid demonstration project in Suzhou, China, as an example, an empirical study is carried out using expert scoring. The comprehensive assessment risk value is 3.8199, and the corresponding risk level is moderate. The results of this work could serve as a reference for the information security protection of smart grids.

The Validity of Information Security Risk Assessment Methods for Organizations

Based on statistical data, a contradiction is shown between an increase in financial investments in the information security (IS) of organizations and a steady increase in the number of IS incidents caused by internal users. A conclusion is made about the cognitive vulnerability and low degree of validity of modern IS risk assessment methods. Stereotypes have been identified, the result of which are cognitive errors in assessing IS risks: the priority of technical protection of information from external threats of IS over organizational and technical protection from internal threats; distrust of the internal client, perception of it exclusively as an object of tough managerial influence, ignoring its subjective role in IS management; restriction of work with personnel within the IS management system with one-time measures and static criteria for assessing human risks and inattention to systemic measures and dynamic, situational criteria. The necessity of updating standards for IS risk management, as well as the development of new methods and tools for assessing, IS risks based on rejecting outdated stereotypes, is substantiated.

Information Security Risk Assessment Method for Ship Control System Based on Fuzzy Sets and Attack Trees

Information security risk assessment for industrial control system is usually influenced by uncertain factors. For effectively dealing with problem that the uncertainty and quantification difficulties are caused by subjective and objective factors in the assessment process, an information security risk assessment method based on attack tree model with fuzzy set theory and probability risk assessment technology is proposed, which is applied in a risk scenario of ship control system. Firstly, potential risks of the control system are analyzed and the attack tree model is established. Then triangular fuzzy numbers and expert knowledge are used to determine the factors that influence the probability of a leaf node and the leaf nodes are quantified to obtain the interval probability. Finally, the fuzzy arithmetic is used to determine the interval probability of the root node and the attack path. After defuzzification, the potential risks of the system and the probability of occurrence of each attack path are obtained. Compared with other methods, the proposed method can greatly reduce the impact of subjectivity on the risk assessment of industrial control systems and get more stable, reliable, and scientific evaluation results.

A framework for estimating information security risk assessment method completeness

In general, an information security risk assessment (ISRA) method produces risk estimates, where risk is the product of the probability of occurrence of an event and the associated consequences for the given organization. ISRA practices vary among industries and disciplines, resulting in various approaches and methods for risk assessments. There exist several methods for comparing ISRA methods, but these are scoped to compare the content of the methods to a predefined set of criteria, rather than process tasks to be carried out and the issues the method is designed to address. It is the lack of an all-inclusive and comprehensive comparison that motivates this work. This paper proposes the Core Unified Risk Framework (CURF) as an all-inclusive approach to compare different methods, all-inclusive since we grew CURF organically by adding new issues and tasks from each reviewed method. If a task or issue was present in surveyed ISRA method, but not in CURF, it was appended to the model, thus obtaining a measure of completeness for the studied methods. The scope of this work is primarily functional approaches risk assessment procedures, which are the formal ISRA methods that focus on assessments of assets, threats, vulnerabilities, and protections, often with measures of probability and consequence. The proposed approach allowed for a detailed qualitative comparison of processes and activities in each method and provided a measure of completeness. This study does not address aspects beyond risk identification, estimation, and evaluation; considering the total of all three activities, we found the “ISO/IEC 27005 Information Security Risk Management” to be the most complete approach at present. For risk estimation only, we found the Factor Analysis of Information Risk and ISO/IEC 27005:2011 as the most complete frameworks. In addition, this study discovers and analyzes several gaps in the surveyed methods.

Security Risk Assessment in Internet of Things Systems

Information security risk assessment methods have served us well over the past two decades. They have provided a tool for organizations and governments to use in protecting themselves against pertinent risks. As the complexity, pervasiveness, and automation of technology systems increases and cyberspace matures, particularly with the Internet of Things (IoT), there is a strong argument that we will need new approaches to assess risk and build trust. The challenge with simply extending existing assessment methodologies to IoT systems is that we could be blind to new risks arising in such ecosystems. These risks could be related to the high degrees of connectivity present or the coupling of digital, cyber-physical, and social systems. This article makes the case for new methodologies to assess risk in this context that consider the dynamics and uniqueness of the IoT while maintaining the rigor of best practice in risk assessment.

Traditional Security Risk Assessment Methods in Cloud Computing Environment: Usability Analysis

The term “Cloud Computing” has become very common in our daily life. Cloud computing has emerged with promises to decrease the cost of computing implementation and deliver the computing as service, where the clients pay only for what he needed and used. However, due to the new structure of the cloud computing model, several security concerns have been raised and many other security threats have been needed to be reevaluated according to the cloud structure. Besides, the traditional security risk assessment methods become unfit for cloud computing model due to its new distinguished characteristics. In this paper, we analysis the traditional information security risk assessment methods’ ability to assess the security risks in cloud computing environments.

Knowledge-based information security risk assessment method

It is an important function for managers to keep away from information security risks. With the increasing complex and scale of information systems, information system security risks may be more difficult to assess and strategies for risk reduction may be lack of objectivity. To solve this problem, this paper proposes a knowledge-based information security risk assessment method in which basic rules and specific rules are defined to match every asset, threat and vulnerability. Basic rules are defined as the rules without influence of external relationships. Specific rules are defined as the rules by user group. Performance analysis shows this method could increase efficiency and ensure accuracy of risk assessment.

Fuzzy Comprehensive Risk Assessment Method Based on Consistent Matrix and Information Entropy

To solve the following problems of information security risk assessment method: inconsistency of judgment matrix, and irrationality of expert weight, risk assessment method based on the consistent matrix and information entropy (RAMCI) is proposed, which uses the priority relationship matrix to establish consistent judgment matrix and information entropy to calculate the weight of multiple experts with an indicator score. This method was used in a case to assess the risk. The results show that: in comparison with previous assessment methods, RAMCI has the following advantages: con- sistency of judgment matrix not concerned; objectively reflects the statistical profile of individual risk factors. So RAMCI is a practical information system risk assessment method.

Development of an E-Healthcare Information Security Risk Assessment Method

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.

A Comparative Study of Risk Assessment Methodologies for Information Systems

In todays dynamic and changing economic environment, businesses are subjected to greater risks than ever before. As a result of this, IT Project Leaders/Managers/Director/Senior Technical Staff should be in a position to identify the business risks that an organization faces and the risk management policies that an organization has to effectively manage those risks. These risks may be related with the Finance, Accounting, Information Systems and their security etc. Here, in this paper, we are emphasizing on Information Systems Security risks. Risk assessment is currently used as a key technique for managing Information Systems Security. Every organization is implementing the risk management methods. Risk assessment is a part of this superset, Risk Management. There are various information security risk assessment methods available that can be implemented by the organization, and each has different approaches to assess the information security risks. Organizations find it difficult to select an information security risk assessment method; therefore there is a need for a critical review of existing risk assessment methodologies. This paper presents a brief discussion on the top risk assessment methodologies, particularly COBRA, CORAS, CRAMM, OCTAVE, SOMAP, and NIST Guide, along with strengths and weaknesses of each one. After that a comparative study is also done on the basis of the review results. Further research directions may also be taken by the weaknesses section. This work provides an evaluation to determine whether an information security risk assessment method is in line with information technology governance or not. The research paper will help the Senior IT Personnel to provide their recommendations for using a risk assessment methodology based on the specific requirements of an organization.
