Evaluation of Efficiency of Cybersecurity

Uurimistöö eesmärgiks on uurida, kuidas tõhus küberjulgeolek on olnud edukas. Uurimistöö kasutab parima võimaliku tulemuse saamiseks mitmesuguseid uurimismeetodeid ja kirjanduse ülevaade on süstemaatiline. Kuid uurimistöö järeldus on see, et uuring ei suuda kinnitada või tagasi lükata peamist töö hüpoteesi. Uuring ei õnnestunud, sest puuduvad korralikud teooriad, mis näitavad ohutuse ja küberjulgeoleku nähtusi ning puuduvad head näitajad, mis annaksid küberohutuse tõhususe kohta kehtivaid ja ratsionaalseid tulemusi, kui hästi on küberkuritegevuse abil õnnestunud küberkuritegevuse tõhusaks võitmiseks ja küberkuritegude tõhusaks vähendamiseks. Seepärast on küberjulgeoleku teadusteooria ja julgeoleku teadusteooria vähearenenud 2018. aastal. Uuringud on teinud küberjulgeoleku ja turvalisuse arendamise põhilisi avastusi. Edasiste põhiuuringute suund on luua üldine turbeteooria, mis kirjeldab ohtlike muutujate ohtlike muutujate kavatsust, ressursse, pädevust ja edusamme ohtlike muutujate ja aksioomide puhul, kus ohtlike muutujate mõõtmisel saab teha selle sisse loodetavas ja teooria kirjeldab, millised on tõhusad meetmed, et vältida ja leevendada ning millised ei ole ja lõpuks kehtestada nõuetekohased mõõdikud, et mõõta turvalisuse ja küberjulgeoleku tõhusust loodetavus ja kehtivusega.The purpose of the thesis is to research how effectively cybersecurity has succeeded on its mission. The thesis used multiple research methods to get best possible answer and the literature review has been systematic. However, the conclusion of the research was that the study is unable to either confirm or reject the main working hypothesis. The study is unable to do it because of the lack of proper theories to describe what are the phenomena in secu-rity and cybersecurity and the lack of proper metrics to give valid and sound conclusion about the effective of cybersecurity and how well have cybersecurity succeed on its mis-sion to effectively prevent and mitigate cybercrime. Therefore, the science of security and science of cybersecurity are underdeveloped in 2018. The research has made basic discov-eries of development of cybersecurity and security. A direction of further basic research is to establish a general theory of security which describes threat variables, threat variables intention, resources, competence and progress of the threat variables and axioms where measurement of threat variables can be made with reliability and the theory would describe which are effective measures to prevent and mitigate and which are not and finally, estab-lish proper metrics to measure efficiency of security and cybersecurity with reliability and validity

Cyber-Physical Threat Intelligence for Critical Infrastructures Security

Modern critical infrastructures comprise of many interconnected cyber and physical assets, and as such are large scale cyber-physical systems. Hence, the conventional approach of securing these infrastructures by addressing cyber security and physical security separately is no longer effective. Rather more integrated approaches that address the security of cyber and physical assets at the same time are required. This book presents integrated (i.e. cyber and physical) security approaches and technologies for the critical infrastructures that underpin our societies. Specifically, it introduces advanced techniques for threat detection, risk assessment and security information sharing, based on leading edge technologies like machine learning, security knowledge modelling, IoT security and distributed ledger infrastructures. Likewise, it presets how established security technologies like Security Information and Event Management (SIEM), pen-testing, vulnerability assessment and security data analytics can be used in the context of integrated Critical Infrastructure Protection. The novel methods and techniques of the book are exemplified in case studies involving critical infrastructures in four industrial sectors, namely finance, healthcare, energy and communications. The peculiarities of critical infrastructure protection in each one of these sectors is discussed and addressed based on sector-specific solutions. The advent of the fourth industrial revolution (Industry 4.0) is expected to increase the cyber-physical nature of critical infrastructures as well as their interconnection in the scope of sectorial and cross-sector value chains. Therefore, the demand for solutions that foster the interplay between cyber and physical security, and enable Cyber-Physical Threat Intelligence is likely to explode. In this book, we have shed light on the structure of such integrated security systems, as well as on the technologies that will underpin their operation. We hope that Security and Critical Infrastructure Protection stakeholders will find the book useful when planning their future security strategies

Nature-inspired survivability: Prey-inspired survivability countermeasures for cloud computing security challenges

As cloud computing environments become complex, adversaries have become highly sophisticated and unpredictable. Moreover, they can easily increase attack power and persist longer before detection. Uncertain malicious actions, latent risks, Unobserved or Unobservable risks (UUURs) characterise this new threat domain. This thesis proposes prey-inspired survivability to address unpredictable security challenges borne out of UUURs. While survivability is a well-addressed phenomenon in non-extinct prey animals, applying prey survivability to cloud computing directly is challenging due to contradicting end goals. How to manage evolving survivability goals and requirements under contradicting environmental conditions adds to the challenges. To address these challenges, this thesis proposes a holistic taxonomy which integrate multiple and disparate perspectives of cloud security challenges. In addition, it proposes the TRIZ (Teorija Rezbenija Izobretatelskib Zadach) to derive prey-inspired solutions through resolving contradiction. First, it develops a 3-step process to facilitate interdomain transfer of concepts from nature to cloud. Moreover, TRIZ’s generic approach suggests specific solutions for cloud computing survivability. Then, the thesis presents the conceptual prey-inspired cloud computing survivability framework (Pi-CCSF), built upon TRIZ derived solutions. The framework run-time is pushed to the user-space to support evolving survivability design goals. Furthermore, a target-based decision-making technique (TBDM) is proposed to manage survivability decisions. To evaluate the prey-inspired survivability concept, Pi-CCSF simulator is developed and implemented. Evaluation results shows that escalating survivability actions improve the vitality of vulnerable and compromised virtual machines (VMs) by 5% and dramatically improve their overall survivability. Hypothesis testing conclusively supports the hypothesis that the escalation mechanisms can be applied to enhance the survivability of cloud computing systems. Numeric analysis of TBDM shows that by considering survivability preferences and attitudes (these directly impacts survivability actions), the TBDM method brings unpredictable survivability information closer to decision processes. This enables efficient execution of variable escalating survivability actions, which enables the Pi-CCSF’s decision system (DS) to focus upon decisions that achieve survivability outcomes under unpredictability imposed by UUUR

A Novel Method for Detecting APT Attacks by Using OODA Loop and Black Swan Theory

Advanced Persistent Threat(APT) attacks are a major concern for the modern societal digital infrastructures due to their highly sophisticated nature. The purpose of these attacks varies from long period espionage in high level environment to causing maximal destruction for targeted cyber environment. Attackers are skilful and well funded by governments in many cases. Due to sophisticated methods it is highly important to study proper countermeasures to detect these attacks as early as possible. Current detection methods under-performs causing situations where an attack can continue months or even years in a targeted environment. We propose a novel method for analysing APT attacks through OODA loop and Black Swan theory by defining them as a multivector multi-stage attacks with continuous strategical ongoing campaign. Additionally it is important to notice that for developing better performing detection methods, we have to find the most common factor within these attacks. We can state that the most common factor of APT attacks is communication, thus environment has to be developed in a way that we are able to capture complete network flow and analyse it.peerReviewe

Fielding Design, Design Fielding:Learning, Leading & Organising in New Territories

A framing question; What does (meaningful) collaboration look like in action? led to the search for and identification of a polycontext, a site where advanced collaborative activity is intelligible. This research aims to explore how the epistemic foundations of learning and design theory can adapt to collaborative approaches to organizing, learning and leadership as the macro-economic transition of digital transformation proceeds. Through embedded ethnographic engagement within a learning organization facilitating group-oriented, design-led collaborative learning experiences, a case study investigates multiple sites within a global organizational network whose distinctive methodology and culture provides a setting emblematic of frontier digital economic activity. The organization’s activity generates environments which notionally act as boundary sites where negotiation of epistemic difference is necessitated, consequently distinctive forms of expertise in brokerage and perspective-taking arise to support dynamic coordination, presenting a distinct take on group-oriented learning. Comprising interacting investigation of communities of facilitators and learning designers tasked to equip learners with distinctive forms of integrative expertise, with the objective of forming individuals adept at rapid orientation to contingent circumstances achieved by collaborative organizing. In parallel, investigating narratives of an organization’s formation led to grounded theory about how collaborative activity is enabled by shared reframing practices. Consequently, the organization anticipates and reshapes the field it operates within, the research discusses scalar effects of learning communities on industry work practices. The inquiry interrogates design-led learning and expertise formation apt for transformative activity within and beyond the digital economy. Exploring how methodological innovations within collaborative learning organizations are enacted and scaled, primary perspectives on design-led, group-oriented learning are evaluated alongside relevant secondary theoretic perspectives on collaborative organizing, learning and leading. The study synthesizes contributions that point to expansions of existing learning paradigms and anticipates how collaborative learning by design intervenes with the schematic assumptions at work in individuals, communities and fields. Observational insight, systematic analysis and theoretical evaluation are applied to problematize assumptions underlying social theory to anticipate generational expansions to the design methods field which responds to inadequacies in planning and organizing approaches applied by design. The research attempts to habituate understanding from outside design methods to better equip an explanatory understanding of contemporary design-led learning and expertise formation occurring in modern professional structures, especially in the creative industries. Together, the research investigates how learners navigate challenges of organizing, learning and leading into unseen territories
