    Cyber insider threat is one of the most difficult risks to mitigate in organizations. However, innovative validated visualizations for cyber analysts to better decipher and react to detected anomalies has not been reported in literature or in industry. Attacks caused by malicious insiders can cause millions of dollars in losses to an organization. Though there have been advances in Intrusion Detection Systems (IDSs) over the last three decades, traditional IDSs do not specialize in anomaly identification caused by insiders. There is also a profuse amount of data being presented to cyber analysts when deciphering big data and reacting to data breach incidents using complex information systems. Information visualization is pertinent to the identification and mitigation of malicious cyber insider threats. The main goal of this study was to develop and validate, using Subject Matter Experts (SME), an executive insider threat dashboard visualization prototype. Using the developed prototype, an experimental study was conducted, which aimed to assess the perceived effectiveness in enhancing the analysts’ interface when complex data correlations are presented to mitigate malicious insiders cyber threats. Dashboard-based visualization techniques could be used to give full visibility of network progress and problems in real-time, especially within complex and stressful environments. For instance, in an Emergency Room (ER), there are four main vital signs used for urgent patient triage. Cybersecurity vital signs can give cyber analysts clear focal points during high severity issues. Pilots must expeditiously reference the Heads Up Display (HUD), which presents only key indicators to make critical decisions during unwarranted deviations or an immediate threat. Current dashboard-based visualization techniques have yet to be fully validated within the field of cybersecurity. This study developed a visualization prototype based on SME input utilizing the Delphi method. SMEs validated the perceived effectiveness of several different types of the developed visualization dashboard. Quantitative analysis of SME’s perceived effectiveness via self-reported value and satisfaction data as well as qualitative analysis of feedback provided during the experiments using the prototype developed were performed. This study identified critical cyber visualization variables and identified visualization techniques. The identifications were then used to develop QUICK.v™ a prototype to be used when mitigating potentially malicious cyber insider threats. The perceived effectiveness of QUICK.v™ was then validated. Insights from this study can aid organizations in enhancing cybersecurity dashboard visualizations by depicting only critical cybersecurity vital signs

    The increasing degree of connectivity in factory of the future (FoF) environments, with systems that were never designed for a networked environment in terms of their technical security nature, is accompanied by a number of security risks that must be considered. This leads to the necessity of relying on risk assessment-based approaches to reach a sufficiently mature cyber security management level. However, the lack of common definitions of cyber threat actors (CTA) poses challenges in untested environments such as the FoF. This paper analyses policy papers and reports from expert organizations to identify common definitions of CTAs. A significant consensus exists only on two common CTAs, while other CTAs are often either ignored or overestimated in their importance. The identified motivations of CTAs are contrasted with the specific characteristics of FoF environments to determine the most likely CTAs targeting FoF environments. Special emphasis is given to corporate competitors, as FoF environments probably provide better opportunities than ever for industrial espionage if they are not sufficiently secured. In this context, the study aims to draw attention to the research gaps in this area

    Future Implications of Emerging Disruptive Technologies on Weapons of Mass Destruction

    This report asks the questions: What are the future implications of Emerging Disruptive Technologies (EDTs) on the future of Weapons of Mass Destruction (WMD) warfare? How might EDTs increase the lethality and effectiveness of WMDs in kinetic warfare in 2040? How can civic leaders and public servants prepare for and mitigate projected threats? Problem  In the coming decade, state and non-state adversaries will use EDTs to attack systems and populations that may initiate and accelerate existing geopolitical conflict escalation. EDTs are expected to be used both in the initial attack or escalation as well as a part of the detection and decision-making process. Due to the speed of EDTs, expected confusion, and common lack of human oversight, attacks will also be incorrectly attributed, which has the capacity to escalate rapid geopolitical conflict to global military conflict, and ultimately, to the use of nuclear WMDs. The use of EDTs in the shadow of nuclear WMDs is also expected to create an existential threat to possible adversaries, pushing them to “lower the bar” of acceptability for using nuclear WMDs. EDTs will enable and embolden insider threats, both willing and unknowing, to effect geopolitical conflict on a global scale. In addition, the combination of multiple EDTs when used together for attacks will create WMD effects on populations and governments. Furthermore, EDTs will be used by adversaries to target and destabilize critical infrastructure systems, such as food, energy, and transportation, etc. that will have a broader effect on populations and governments. EDTs will enable adversaries to perpetrate a long-game attack, where the effect and attribution of the attack may not be detected for an extended period -- if ever. Solution  To combat these future threats, organizations will need to conduct research and intelligence gathering paired with exploratory research and development to better understand the state of EDTs and their potential impacts. With this information, organizations will need to conduct collaborative “wargaming” and planning to explore a range of possible and potential threats of EDTs. The knowledge gained from all of these activities will inform future training and best practices to prepare for and address these threats. Organizations will also need to increase their investments in EDT related domains, necessitating countries to not only change how they fight, but also evolve their thinking about deterrence. Expanded regulation, policy making, and political solidarity among members will take on an increasingly more significant and expanded role. Broader government, military, and civilian cooperation will be needed to disrupt and mitigate some of these future threats in conjunction with broader public awareness. All of these actions will place a higher value on cooperation and shared resiliency among NATO members

    Air Power’s Cyber Risk: How Operational Causes will have Strategic Consequences

    Get PDF
    This thesis argues that air power's cyber risk which has emerged from operational causes will create profound strategic consequences. Through a comprehensive examination of existing literature, it challenges prevailing perspectives by highlighting a critical gap in knowledge: a failure to map the link between operational causes and strategic consequences of air power’s cyber risk which, when realised, will threaten the roles and, in extremis, survival of states. While acknowledging the risks emergent nature and situational specificity with not all states reliant on air power and size inverse to severity, the thesis asserts that the realisation of these strategic consequences is a matter of 'when', not 'if'. Developed within a risk management framework, supported by literature reviews and case studies, and leading to observations and recommendations, the thesis responds by offering a pathway for further research which can mitigate air power’s cyber risk. If embraced, an opportunity exists for academia and practitioners to act in synergy, fill the identified gap in knowledge and address the risk proactively. Conversely, if ignored and the pathway is not followed, the implications will, the thesis predicts, result in the unmitigated strategic consequences of air power’s cyber risk reshaping the geopolitical landscape of the 21st century

    Tesis por compendio[ES] La información y los sistemas que la tratan son un activo a proteger para personas, organizaciones e incluso países enteros. Nuestra dependencia en las tecnologías de la información es cada día mayor, por lo que su seguridad es clave para nuestro bienestar. Los beneficios que estas tecnologías nos proporcionan son incuestionables, pero su uso también introduce riesgos que ligados a nuestra creciente dependencia de las mismas es necesario mitigar. Los actores hostiles avanzados se categorizan principalmente en grupos criminales que buscan un beneficio económico y en países cuyo objetivo es obtener superioridad en ámbitos estratégicos como el comercial o el militar. Estos actores explotan las tecnologías, y en particular el ciberespacio, para lograr sus objetivos. La presente tesis doctoral realiza aportaciones significativas a la caracterización de los actores hostiles avanzados y a la detección de sus actividades. El análisis de sus características es básico no sólo para conocer a estos actores y sus operaciones, sino para facilitar el despliegue de contramedidas que incrementen nuestra seguridad. La detección de dichas operaciones es el primer paso necesario para neutralizarlas, y por tanto para minimizar su impacto. En el ámbito de la caracterización, este trabajo profundiza en el análisis de las tácticas y técnicas de los actores. Dicho análisis siempre es necesario para una correcta detección de las actividades hostiles en el ciberespacio, pero en el caso de los actores avanzados, desde grupos criminales hasta estados, es obligatorio: sus actividades son sigilosas, ya que el éxito de las mismas se basa, en la mayor parte de casos, en no ser detectados por la víctima. En el ámbito de la detección, este trabajo identifica y justifica los requisitos clave para poder establecer una capacidad adecuada frente a los actores hostiles avanzados. Adicionalmente, proporciona las tácticas que deben ser implementadas en los Centros de Operaciones de Seguridad para optimizar sus capacidades de detección y respuesta. Debemos destacar que estas tácticas, estructuradas en forma de kill-chain, permiten no sólo dicha optimización, sino también una aproximación homogénea y estructurada común para todos los centros defensivos. En mi opinión, una de las bases de mi trabajo debe ser la aplicabilidad de los resultados. Por este motivo, el análisis de tácticas y técnicas de los actores de la amenaza está alineado con el principal marco de trabajo público para dicho análisis, MITRE ATT&CK. Los resultados y propuestas de esta investigación pueden ser directamente incluidos en dicho marco, mejorando así la caracterización de los actores hostiles y de sus actividades en el ciberespacio. Adicionalmente, las propuestas para mejorar la detección de dichas actividades son de aplicación directa tanto en los Centros de Operaciones de Seguridad actuales como en las tecnologías de detección más comunes en la industria. De esta forma, este trabajo mejora de forma significativa las capacidades de análisis y detección actuales, y por tanto mejora a su vez la neutralización de operaciones hostiles. Estas capacidades incrementan la seguridad global de todo tipo de organizaciones y, en definitiva, de nuestra sociedad.[CA] La informació i els sistemas que la tracten són un actiu a protegir per a persones, organitzacions i fins i tot països sencers. La nostra dependència en les tecnologies de la informació es cada dia major, i per aixó la nostra seguretat és clau per al nostre benestar. Els beneficis que aquestes tecnologies ens proporcionen són inqüestionables, però el seu ús també introdueix riscos que, lligats a la nostra creixent dependència de les mateixes és necessari mitigar. Els actors hostils avançats es categoritzen principalment en grups criminals que busquen un benefici econòmic i en països el objectiu dels quals és obtindre superioritat en àmbits estratègics, com ara el comercial o el militar. Aquests actors exploten les tecnologies, i en particular el ciberespai, per a aconseguir els seus objectius. La present tesi doctoral realitza aportacions significatives a la caracterització dels actors hostils avançats i a la detecció de les seves activitats. L'anàlisi de les seves característiques és bàsic no solament per a conéixer a aquests actors i les seves operacions, sinó per a facilitar el desplegament de contramesures que incrementen la nostra seguretat. La detección de aquestes operacions és el primer pas necessari per a netralitzar-les, i per tant, per a minimitzar el seu impacte. En l'àmbit de la caracterització, aquest treball aprofundeix en l'anàlisi de lestàctiques i tècniques dels actors. Aquesta anàlisi sempre és necessària per a una correcta detecció de les activitats hostils en el ciberespai, però en el cas dels actors avançats, des de grups criminals fins a estats, és obligatòria: les seves activitats són sigiloses, ja que l'éxit de les mateixes es basa, en la major part de casos, en no ser detectats per la víctima. En l'àmbit de la detecció, aquest treball identifica i justifica els requisits clau per a poder establir una capacitat adequada front als actors hostils avançats. Adicionalment, proporciona les tàctiques que han de ser implementades en els Centres d'Operacions de Seguretat per a optimitzar les seves capacitats de detecció i resposta. Hem de destacar que aquestes tàctiques, estructurades en forma de kill-chain, permiteixen no només aquesta optimització, sinò tambié una aproximació homogènia i estructurada comú per a tots els centres defensius. En la meva opinio, una de les bases del meu treball ha de ser l'aplicabilitat dels resultats. Per això, l'anàlisi de táctiques i tècniques dels actors de l'amenaça està alineada amb el principal marc públic de treball per a aquesta anàlisi, MITRE ATT&CK. Els resultats i propostes d'aquesta investigació poden ser directament inclosos en aquest marc, millorant així la caracterització dels actors hostils i les seves activitats en el ciberespai. Addicionalment, les propostes per a millorar la detecció d'aquestes activitats són d'aplicació directa tant als Centres d'Operacions de Seguretat actuals com en les tecnologies de detecció més comuns de la industria. D'aquesta forma, aquest treball millora de forma significativa les capacitats d'anàlisi i detecció actuals, i per tant millora alhora la neutralització d'operacions hostils. Aquestes capacitats incrementen la seguretat global de tot tipus d'organitzacions i, en definitiva, de la nostra societat.[EN] Information and its related technologies are a critical asset to protect for people, organizations and even whole countries. Our dependency on information technologies increases every day, so their security is a key issue for our wellness. The benefits that information technologies provide are questionless, but their usage also presents risks that, linked to our growing dependency on technologies, we must mitigate. Advanced threat actors are mainly categorized in criminal gangs, with an economic goal, and countries, whose goal is to gain superiority in strategic affairs such as commercial or military ones. These actors exploit technologies, particularly cyberspace, to achieve their goals. This PhD Thesis significantly contributes to advanced threat actors' categorization and to the detection of their hostile activities. The analysis of their features is a must not only to know better these actors and their operations, but also to ease the deployment of countermeasures that increase our security. The detection of these operations is a mandatory first step to neutralize them, so to minimize their impact. Regarding characterization, this work delves into the analysis of advanced threat actors' tactics and techniques. This analysis is always required for an accurate detection of hostile activities in cyberspace, but in the particular case of advances threat actors, from criminal gangs to nation-states, it is mandatory: their activities are stealthy, as their success in most cases relies on not being detected by the target. Regarding detection, this work identifies and justifies the key requirements to establish an accurate response capability to face advanced threat actors. In addition, this work defines the tactics to be deployed in Security Operations Centers to optimize their detection and response capabilities. It is important to highlight that these tactics, with a kill-chain arrangement, allow not only this optimization, but particularly a homogeneous and structured approach, common to all defensive centers. In my opinion, one of the main bases of my work must be the applicability of its results. For this reason, the analysis of threat actors' tactics and techniques is aligned with the main public framework for this analysis, MITRE ATT&CK. The results and proposals from this research can be directly included in this framework, improving the threat actors' characterization, as well as their cyberspace activities' one. In addition, the proposals to improve these activities' detection are directly applicable both in current Security Operations Centers and in common industry technologies. In this way, I consider that this work significantly improves current analysis and detection capabilities, and at the same time it improves hostile operations' neutralization. These capabilities increase global security for all kind of organizations and, definitely, for our whole society.Villalón Huerta, A. (2023).

    Full text link
    The smart grid is a large-scale complex system that integrates communication technologies with the physical layer operation of the energy systems. Security and resilience mechanisms by design are important to provide guarantee operations for the system. This chapter provides a layered perspective of the smart grid security and discusses game and decision theory as a tool to model the interactions among system components and the interaction between attackers and the system. We discuss game-theoretic applications and challenges in the design of cross-layer robust and resilient controller, secure network routing protocol at the data communication and networking layers, and the challenges of the information security at the management layer of the grid. The chapter will discuss the future directions of using game-theoretic tools in addressing multi-layer security issues in the smart grid.Comment: 16 page

    Capability maturity model and metrics framework for cyber cloud security

    Full text link
    © 2017 SCPE. Cyber space is affecting all areas of our life. Cloud computing is the cutting-edge technology of this cyber space and has established itself as one of the most important resources sharing technologies for future on-demand services and infrastructures that support Internet of Things (IOTs), big data platforms and software-defined systems/services. More than ever, security is vital for cloud environment. There exist several cloud security models and standards dealing with emerging cloud security threats. However, these models are mostly reactive rather than proactive and they do not provide adequate measures to assess the overall security status of a cloud system. Out of existing models, capability maturity models, which have been used by many organizations, offer a realistic approach to address these problems using management by security domains and security assessment on maturity levels. The aim of the paper is twofold: first, it provides a review of capability maturity models and security metrics; second, it proposes a cloud security capability maturity model (CSCMM) that extends existing cyber security models with a security metric framework

    In Nigeria, microfinance banks (MFB) face the burden of investing in cyber security to protect their databases, prevent monetary losses, maintain customer trust, and remain afloat in a competitive business environment. However, there are incessant cyber risks and attacks by criminals who gain undue access to the cyber-space of MFB and cause financial and non-financial loss. The objective of this quantitative study was to examine the effect of cyber security on the business sustainability of three listed, and most valued MFBs in Nigeria. The population of the study was 315 senior, medium and junior employees of three MFBs in Nigeria. As the target population was manageable, the research adopted a census. Data were collected using a semi-structured questionnaire, and the formulated hypothesis was analysed using multiple regression. The study found that cyber security has a significant and positive impact on the sustainability of MFB in Nigeria. Data availability account for the largest contribution to the sustainability of MFBs, followed by data confidentiality and data integrity. Employees in a MFB uphold that data availability, confidentiality, and integrity are pivotal elements of cyber security that influence the sustainability of their organisations in Nigeria. Given these results from the viewpoint of employees, MFBs are implored to regularly review and strengthen their risk management strategy and adopt a more integrative approach of human-centric cybersecurity, which brings technology and human elements together to address current and future cyber risks and build and sustain consumer trust in digital financial transactions. The implication of the study and areas for future research are highlighted

    An analysis of cybersecurity culture in an organisation managing Critical Infrastructure

    Get PDF
    The 4th industrial revolution (4IR) is transforming the way businesses operate, making them more efficient and data-driven while also increasing the threat-landscape brought on by the convergence of technologies and increasingly so for organisations managing critical infrastructure. Environments that traditionally operated entirely independent of networks and the internet are now connecting in ways that are exposing critical infrastructure to a new level of cyber-risks that now need to be managed. Due to the stable nature of technologies and knowledge in traditional industrial environments, there is a misalignment of skills to emerging technology trends. Globally cyber-crime attacks are on the rise with Cisco reporting in 2018 that 31% of all respondents had seen a cyber-attack in their operational environment[1]. With up to 67% of breaches reported in the Willis Towers report due to employee negligence [2], the importance of cybersecurity culture is no longer in question in organisations managing critical infrastructure. Developing an understanding of the drivers for behaviours, attitudes and beliefs related to cybersecurity and aligning these to an organisations risk appetite and tolerance is crucial to managing cyber-risk. There is a very divergent understanding of cyber-risk in the engineering environment. This study endeavours to investigate employee perceptions, attitudes and values associated with cybersecurity and how these potentially affects their behaviour and ultimately the risk to the plant or organisation. Most traditional culture questionnaires focus on information security with observations focussing more on social engineering, email hygiene and physical controls. This cybersecurity culture study was conducted to gain insight into people's beliefs, attitudes and behaviours related to cybersecurity encompassing people, process and technology focussing on the operational technology environment in Eskom1. Both technical (Engineering and IT) and nontechnical (business support staff) staff were questionnaireed. The questionnaire was categorised into four sections dealing with cybersecurity culture as they relate to individuals, processes and technology, leadership and the organisation at large. The results from the analysis, revealed that collaboration, information sharing, reporting of vulnerabilities, high dependence and trust in technology, leadership commitment, vigilance, compliance, unclear processes and lack of understanding around cybersecurity all contribute to the current levels of cybersecurity culture. Insights from this study will generate recommendations that will form part of a cybersecurity culture transformation journey
