Three Decades of Deception Techniques in Active Cyber Defense -- Retrospect and Outlook
Deception techniques have been widely seen as a game changer in cyber
defense. In this paper, we review representative techniques in honeypots,
honeytokens, and moving target defense, spanning from the late 1980s to the
year 2021. Techniques from these three domains complement with each other and
may be leveraged to build a holistic deception based defense. However, to the
best of our knowledge, there has not been a work that provides a systematic
retrospect of these three domains all together and investigates their
integrated usage for orchestrated deceptions. Our paper aims to fill this gap.
By utilizing a tailored cyber kill chain model which can reflect the current
threat landscape and a four-layer deception stack, a two-dimensional taxonomy
is developed, based on which the deception techniques are classified. The
taxonomy literally answers which phases of a cyber attack campaign the
techniques can disrupt and which layers of the deception stack they belong to.
Cyber defenders may use the taxonomy as a reference to design an organized and
comprehensive deception plan, or to prioritize deception efforts for a budget
conscious solution. We also discuss two important points for achieving active
and resilient cyber defense, namely deception in depth and deception lifecycle,
where several notable proposals are illustrated. Finally, some outlooks on
future research directions are presented, including dynamic integration of
different deception techniques, quantified deception effects and deception
operation cost, hardware-supported deception techniques, as well as techniques
developed based on better understanding of the human element.Comment: 19 page
SYNERGY OF BUILDING CYBERSECURITY SYSTEMS
The development of the modern world community is closely related to advances in computing resources and cyberspace. The formation and expansion of the range of services is based on the achievements of mankind in the field of high technologies. However, the rapid growth of computing resources, the emergence of a full-scale quantum computer tightens the requirements for security systems not only for information and communication systems, but also for cyber-physical systems and technologies.
The methodological foundations of building security systems for critical infrastructure facilities based on modeling the processes of behavior of antagonistic agents in security systems are discussed in the first chapter.
The concept of information security in social networks, based on mathematical models of data protection, taking into account the influence of specific parameters of the social network, the effects on the network are proposed in second chapter.
The nonlinear relationships of the parameters of the defense system, attacks, social networks, as well as the influence of individual characteristics of users and the nature of the relationships between them, takes into account.
In the third section, practical aspects of the methodology for constructing post-quantum algorithms for asymmetric McEliece and Niederreiter cryptosystems on algebraic codes (elliptic and modified elliptic codes), their mathematical models and practical algorithms are considered. Hybrid crypto-code constructions of McEliece and Niederreiter on defective codes are proposed. They can significantly reduce the energy costs for implementation, while ensuring the required level of cryptographic strength of the system as a whole. The concept of security of corporate information and educational systems based on the construction of an adaptive information security system is proposed.

Розвиток сучасної світової спільноти тісно пов’язаний з досягненнями в області обчислювальних ресурсів і кіберпростору. Формування та розширення асортименту послуг базується на досягненнях людства у галузі високих технологій. Однак стрімке зростання обчислювальних ресурсів, поява повномасштабного квантового комп’ютера посилює вимоги до систем безпеки не тільки інформаційно-комунікаційних, але і до кіберфізичних систем і технологій.
У першому розділі обговорюються методологічні основи побудови систем безпеки для об'єктів критичної інфраструктури на основі моделювання процесів поведінки антагоністичних агентів у систем безпеки.
У другому розділі пропонується концепція інформаційної безпеки в соціальних мережах, яка заснована на математичних моделях захисту даних, з урахуванням впливу конкретних параметрів соціальної мережі та наслідків для неї.
Враховуються нелінійні взаємозв'язки параметрів системи захисту, атак, соціальних мереж, а також вплив індивідуальних характеристик користувачів і характеру взаємовідносин між ними.
У третьому розділі розглядаються практичні аспекти методології побудови постквантових алгоритмів для асиметричних криптосистем Мак-Еліса та Нідеррейтера на алгебраїчних кодах (еліптичних та модифікованих еліптичних кодах), їх математичні моделі та практичні алгоритми. Запропоновано гібридні конструкції криптокоду Мак-Еліса та Нідеррейтера на дефектних кодах. Вони дозволяють істотно знизити енергетичні витрати на реалізацію, забезпечуючи при цьому необхідний рівень криптографічної стійкості системи в цілому. Запропоновано концепцію безпеки корпоративних інформаційних та освітніх систем, які засновані на побудові адаптивної системи захисту інформації.

Digital transformation and organizational implications
Digital technologies surround us. Some technologies, such as platforms, help us book our holidays, others, like apps, transform our appearance, and more sophisticated technology, such as artificial intelligence, even translates texts for us. With that in mind, it seems almost unbelievable that there are yet areas in our lives that are not digital but require pen and paper. This dissertation aims to gain a better understanding of the ongoing digital transformation of organizations, with a specific focus on the following aspects: (1) understand what digital transformation is and how it affects firms, (2) shed light on the business value implications and contingencies in the SME context, and (3) to unravel different actions on how firms may deal with institutional pressure. Chapter 2 addresses the conceptual nature of digital transformation through a literature review and provides a process model for different stages of digital change and insights on transforming from the analog world into a digitally transformed organization. Chapter 3 deals with the business value implications of digital transformation for small to medium firms (SMEs) by focusing on the pressure between doing radically different activities and overcoming established routines is provided. Chapter 4 takes a broader perspective on the institutional arrangement and how digital transformation may promote legitimacy challenges. Finally, Chapter 5 ties everything together, presents a general discussion of the different studies and their outcomes, explores managerial and societal implications, and offers future research directions

Towards an Uncertainty-Aware Adaptive Decision Engine for Self-Protecting Software: an POMDP-based Approach
The threats posed by evolving cyberattacks have led to increased research
related to software systems that can self-protect. One topic in this domain is
Moving Target Defense (MTD), which changes software characteristics in the
protected system to make it harder for attackers to exploit vulnerabilities.
However, MTD implementation and deployment are often impacted by run-time
uncertainties, and existing MTD decision-making solutions have neglected
uncertainty in model parameters and lack self-adaptation. This paper aims to
address this gap by proposing an approach for an uncertainty-aware and
self-adaptive MTD decision engine based on Partially Observable Markov Decision
Process and Bayesian Learning techniques. The proposed approach considers
uncertainty in both state and model parameters; thus, it has the potential to
better capture environmental variability and improve defense strategies. A
preliminary study is presented to highlight the potential effectiveness and
challenges of the proposed approach
