The legal tools applied in the context of IT technology development failing to solve the problems facing society. On the other hand, the development of innovation is sometimes hindered. The intensity of the development of information systems and technologies requires highly flexible and adaptive approaches to cybersecurity. One of these approaches is IT risk assessment. There are currently many methodologies that can be used to effectively assess cyber threats. For institutions with multiple exposures, the correlation between different positions may not be correctly estimated. Measuring known risk is a common problem in risk assessment practice. In order to develop a simple IT risk assessment method, the article examines existing IT risk assessment methods, proposes IT risk assessment solutions and presents the results of practical application.

The South Sumatra Gas Pipeline has a total length of 250 km and varies in pipe size. It delivers 250 MMSCFD gas from scattered gas fields to gas markets in Palembang, the industrial center in South Sumatra. The 16-inch Rambutan-Betung segment has ruptured three times. Based on these failures a maintenance program was conducted to avoid similar problems in other segments. These programs were accelerated inline inspection, rupture investigation using Fault Tree Analysis (FTA) method, failure analysis and evaluation of risk assessment methods. The evaluation of risk assessment methods addresses the following considerations: Is the risk assessment method that has been used applicable? Which risk assessment method is more accurate? What actions are necessary to improve risk assessment in the future? Risk assessment methods by AGA PIMAR (American Gas Association Methods for Prioritizing Pipeline Maintenance And Rehabilitation) and Kent. W Muhlbauer method were evaluated and compared. The evaluation was applied based on five conditions. These conditions are before failure/rupture, after rupture, after intelligent pigging, after failure analysis and condition before failures but having high potential land movement. The last condition was included because the failure analysis indicated that ruptured was caused by land movement (land slide). The risk assessment evaluation indicated that each of the assessment methods used was applicable and accurate for different pipeline conditions. For the South Sumatra Gas Pipeline AGA PIMAR was found to be more suitable for the segments evaluated. This evaluation concludes that there is no exact method for implementation of risk assessment; engineering judgment is required in the process.

Discrimination Factors

Chongqing is located in southwestern China, and geological disasters occur frequently. The amount of potential landslide disasters is far greater than the number of landslides that can be managed by government funds, so the risk assessment for potential landslide disasters is critical. In practical applications, risk assessment methods based on landslide stability and loss are restricted by various factors. These methods can be simplified to semi-empirical assessment methods, which are influenced by the discrimination factors near the limit values of the determined conditions, possibly leading to sudden changes in the evaluation results and distort the conclusions. To solve this problem, we propose a full quantitative risk assessment method according to the probability of landslide damage. The mathematical probability model is used to quantitatively describe the risk assessment impacting factors, weaken the boundary influence, and improve the accuracy of landslide risk assessment. Correspondingly, the software is developed to conduct quantitative risk assessment on six landslides in Feng jie County, Chongqing, which verifies the accuracy and reliability of the full quantitative risk assessment method, and provides an important reference for judging urban landslide geological disasters.

Criticality Analysis

Objective: Performing a multiple factor analysis of the existing risk assessment methods based on the developed applicability characteristics for a given method at risk assessment phases. To ensure both industrial and environmental safety, a risk-based approach has become specifically relevant as one of the efficient instruments used in crisis management. Methods: When a risk analysis for hazardous industrial facilities is performed for potential emergencies, such analysis should be done along two primary lines – identifying the risk for preventive protection and insurance measures to be correctly arranged and implemented, as well as forecasting how the consequences of risks actualized will evolve for immediate protective measures to be arranged and planned in good time. At the same time, there are now scores of risk assessment methods, approaches and methodical guidelines for calculation that are notionally divided into five primary groups: observation methods, supplementary methods, scenario analysis, functional analysis, statistical methods. Each risk assessment method has its own specifics, field of use, relevant parameters and qualitative and quantitative characteristics expressed. Results: maintenance and toxicological risk assessment are excluded from the risk assessment methods, the most efficient methods being identified as follows: Failure mode and effects analysis (FMEA) and Failure mode, effects and criticality analysis (FMECA), maintenance focused on reliability assurance, Human reliability analysis (HRA), Event tree analysis (ETA), Layer of protection analysis (LOPA), Structured what if technique (SWIFT). Practical importance: For making a reasonable choice between the methods, benchmarking for the above methods has been performed on which basis the most acceptable approaches are identified. The resulting risk assessment method comparison table has a practical relevance for design and research work performed in forecasting and analyzing industrial and environmental hazards.

Project Risk Assessment

Based on the domestic and overseas researches of project risk assessment methods, this paper classifies project risk assessment methods into subjective judgment methods, evidence and deduction methods, system simulation methods and other methods. After exploring their definitions, advantages and disadvantages, this paper points out that subjective judgment and empirical analogy become two mainstream risk assessment methods. In the end, this paper claims that a risk assessment method does not need any unfathomable theory for its obvious engineering characteristics, but focuses on operability and applicability.

Risk Assessment Method

Successful implementation of Health and Safety (H&S) systems requires an effective mechanism to assess risk. Existing methods focus primarily on measuring the safety aspect; the risk of an accident is determined based on the product of severity of consequence and likelihood of the incident arising. The health component, i.e., chronic harm, is more difficult to assess. Partially, this is due to both consequences and the likelihood of health issues, which may be indeterminate. There is a need to develop a quantitative risk measurement for H&S risk management and with better representation for chronic health issues. The present paper has approached this from a different direction, by adopting a public health perspective of quality of life. We have then changed the risk assessment process to accommodate this. This was then applied to a case study. The case study showed that merely including the chronic harm scales appeared to be sufficient to elicit a more detailed consideration of hazards for chronic harm. This suggests that people are not insensitive to chronic harm hazards, but benefit from having a framework in which to communicate them. A method has been devised to harmonize safety and harm risk assessments. The result was a comprehensive risk assessment method with consideration of safety accidents and chronic health issues. This has the potential to benefit industry by making chronic harm more visible and hence more preventable.
