    Ransomware: Evolution, Mitigation and Prevention

    Get PDF
    Ransomware is a rapidly growing threat to the data files of individuals and businesses. It encrypts files on an infected computer and holds the key to decrypt the files until the victim pays a ransom. This malware is responsible for hundreds of millions of dollars of losses annually. Due to the large amounts of money to be made, new versions appear frequently. This allows bypassing antivirus software and other intrusion detection methods. In this paper, we present a brief history of ransomware, the arguments for and against paying the ransom, best practices to prevent an infection, and to recover from an infection should one happen

    This paper presents an analysis of risk mitigation measures taken by countries around the world facing the current COVID-19 outbreak. In light of the current pandemic the authors collated and clustered (using harmonised terminology) the risk mitigation measures taken around the globe in the combat to contain, and since March 11 2020, to limiting the spread of the SARS-CoV-2 virus known to cause the Coronavirus disease 2019 (COVID-19). This overview gathers lessons learnt, provides an update on the current knowledge for authorities, sectors and first responders on the effectiveness and may allow enhanced prevention, preparedness and response for future outbreaks. Various measures such as mobility restrictions, physical distancing, hygienic measures, socio economic restrictions, communication and international support mechanisms have been clustered and are reviewed in terms of the nature of the actions taken and their qualitative early-perceived impact. At the time of writing, it is still too premature to express the quantitative effectiveness of each risk mitigation cluster, but it seems that the best mitigation results are reported when applying a combination of voluntary and enforceable measures.JRC.E.7-Knowledge for Security and Migratio

    The Center for Preventive Action's annual Preventive Priorities Survey (PPS) evaluates ongoing and potential conflicts based on their likelihood of occurring in the coming year and their impact on U.S. interests. The PPS aims to help the U.S. policymaking community prioritize competing conflict prevention and mitigation demands. Read the 2015 report to find out which conflicts were ranked the top preventive priorities for U.S. policymakers

    Barriers to Mitigation: A Pilot Study

    This pilot research was undertaken to discover barriers that prevent homeowners from mitigating earthquake hazards in their homes. There is a relatively significant body of literature on disaster mitigation, which is reviewed and summarized in this report. However, no studies address how these barriers may be overcome so that homeowners would be more proactive in mitigation. If the barriers can be identified, then future communications and policy actions that address these barriers can be taken, resulting in more widespread mitigation implementation that reduces the injury and damage potential that communities face, leading to a reduction in the post-disaster response requirement, and the time required to achieve recovery. Data came from an online survey of San José State University employees; the survey took approximately 15 minutes for respondents to complete. Questions addressed home characteristics, demographic characteristics, perceptions of earthquake risk, levels of mitigation, past experience with earthquake injury or damage, social influences on hazard and damage prevention, and reactions to various incentives. Statistical analyses were done using SPSS version 16.0. Of the total 331 respondents, 215 were homeowners and consequently used for data analysis. Of these homeowners, 79 % owned single-family homes. The sample overwhelmingly expects a major earthquake to occur within the next 10 years, and most expect to suffer earthquake-caused injuries and damage within their homes in the near future. The findings indicate the importance of earthquake expectations and the social network for influencing mitigation. Physical proximity to others who experienced earthquake damage and relational closeness to those who have taken mitigation actions were found to have a positive effect on mitigation implementation by individuals. Homeowners assumed responsibility for mitigation, and cost is generally not a concern. The most prevalent obstacles to mitigation were the feeling that the mitigation is not necessary or that it is inconvenient. Home structures and systems mitigation is far more commonplace than home contents mitigation. Mitigation of home contents was perceived as not being very important, and this perception prevents individuals from taking mitigation actions. All incentive types that were presented to respondents, which were primarily financial in nature, were reported as likely to increase mitigation. Providing advice and information was also reported to likely result in higher levels of mitigation. The development of mitigation approaches that are low-cost and simple is expected to have a positive effect on mitigation actions. In addition, codes were found to be effective at prompting mitigation – most respondents had mitigated for items that have code requirements. One outcome of this is that mitigation of structures is more widely reported than mitigation of home contents. More research is needed to explore non-financial incentives for mitigation, including incentives provided by personal relationships and how social relationships may be leveraged. There is also a need to explore whether different types of incentives (such as free labor or education) would be more or less effective at prompting particular mitigation actions (such as securing the foundation or strapping down appliances). It would be helpful to take a “bottom up” approach by conducting focus groups on these topics. Demographic effects on mitigation and barriers to mitigation also need to be explored further. There were suggestions that demography mattered, but the sample size for this survey was not sufficiently large to draw statistically valid conclusions. There is also a need to revise the survey instrument to remove some ambiguities and inadequacies that currently exist. It would be useful to explore why persons might have taken particular mitigation actions and how social networks affect their mitigation action, among other things. Heightened perceptions of earthquake threats, experience with earthquake injuries and damage, and social relationships are critical predictors of mitigation. Individuals who know others who have mitigated are more likely to mitigate; therefore improved communications, on the personal level, on the topic of mitigation can be effective. Given the perceptions of mitigating home contents, the public also needs to be made more aware of the threats posed by home contents during an earthquake

    DDoS Attacks: Coverage, Mitigation, and Prevention

    Get PDF
    The Internet is a complex system of autonomous but cooperating networks that constitute a critical Infrastructure with a vast socio-economic significance. Any disruption of the Internet and its services has detrimental effects to its users, be it in the private sector or the industry. This is why Internet research aims for observing, mitigating, and ultimately preventing attacks. In this thesis, we provide methodologies to evaluate and extend the coverage of attack observations, we assess the efficacy of current and emerging attack mitigation solutions, and we identify new opportunities for attack prevention. We do so by utilizing two major vantage point positions, the Internet core and the Internet edge. Our contributions have an operational impact on today's Internet but also its future deployment

    Cyclic blackout mitigation and prevention

    Severe and long-lasting power shortages plague many countries, resulting in cyclic blackouts affecting the life of millions of people. This research focuses on the design, development and evolution of a computer-controlled system for chronic cyclic blackouts mitigation based on the use of an agent-based distributed power management system integrating Supply Demand Matching (SDM) with the dynamic management of Heat, Ventilation, and Air Conditioning (HVAC) appliances. The principle is supported through interlocking different types of HVAC appliances within an adaptive cluster, the composition of which is dynamically updated according to the level of power secured from aggregating the surplus power from underutilised standby generation which is assumed to be changing throughout the day. The surplus power aggregation provides a dynamically changing flow, used to power a basic set of appliances and one HVAC per household. The proposed solution has two modes, cyclic blackout mitigation and prevention modes, selecting either one depends on the size of the power shortage. If the power shortage is severe, the system works in its cyclic blackout mitigation mode during the power OFF periods of a cyclic blackout. The system changes the composition of the HVAC cluster so that its demand added to the demand of basic household appliances matches the amount of secured supply. The system provides the best possible air conditioning/cooling service and distributes the usage right and duration of each type of HVAC appliance either equally among all houses or according to house temperature. However if the power shortage is limited and centred around the peak, the system works in its prevention mode, in such case, the system trades a minimum number of operational air conditioners (ACs) with air cooling counterparts in so doing reducing the overall demand. The solution assumes the use of a new breed of smart meters, suggested in this research, capable of dynamically rationing power provided to each household through a centrally specified power allocation for each family. This smart meter dynamically monitors each customer’s demand and ensures their allocation is never exceeded. The system implementation is evaluated utilising input power usage patterns collected through a field survey conducted in a residential quarter in Basra City, Iraq. The results of the mapping formed the foundation for a residential demand generator integrated in a custom platform (DDSM-IDEA) built as the development environment dedicated for implementing and evaluating the power management strategies. Simulation results show that the proposed solution provides an equitably distributed, comfortable quality of life level during cyclic blackout periods.Severe and long-lasting power shortages plague many countries, resulting in cyclic blackouts affecting the life of millions of people.

    Health and Safety Risk Mitigation among Artisanal and Small-Scale Gold Miners in Zimbabwe

    Get PDF
    Artisanal and small-scale gold mining (ASGM) is often associated with no or compromised attention to health and safety. Although headlines of fatal accidents in Zimbabwe characterise ASGM, little attention is paid to prevention strategies. This study, therefore, explores health and safety risk mitigation in ASGM in Zimbabwe to inform prevention strategies. A qualitative design was used with focus group discussions and in-depth interviews. Data were analysed using thematic analysis, coding, and descriptive statistics. Reported factors contributing to compromised health and safety included immediate causes, workplace factors, ASM related factors, and contextual factors, with interconnectedness between the causal factors. In addition, factors related to ASGM were significant. For risk mitigation, formalisation, organisation of risk reduction, behaviour change, and enforcement of prevention strategies is proposed. A multi-causal analysis is recommended for risk assessment and accident investigation. A multi-stakeholder approach could be considered for risk mitigation including community and public health interventions. However, risk mitigation has been characterised by gaps and weaknesses such as lacking ASM policy, lack of capital, poor enforcement, negative perceptions, and non-compliance. Therefore, we recommend addressing the threats associated with health and safety mitigation to ensure health and safety protection in ASGM

    Perilaku UMKM Dalam Menggunakan Fintech: Fokus Regulatory dan Mitigasi Risiko

    Get PDF
    The purpose of this research is to evaluate the use of fintech by conducting a study of the behavior of MSME actors, both that focus on promotion and focus on prevention of risk mitigation in the use of fintech. Data collected using a questionnaire with respondents who use MSME using fintech (payment). This study analyzes the data using the Structural Equation Model (SEM) by going through two stages of data analysis, namely evaluating the measurement model and testing the hypotheses that are built. The results showed that traits that focused on promotion would always try to choose risk while traits that focused on prevention would try to avoid risks. The risk mitigation of fintech carried out by users will increase according to the willingness of MSME actors to use fintech. So in other words, the higher the risk, the individual character that focuses on promotion and focuses on prevention will affect the intention to use fintech.
