This thesis aims to develop a technical representation of the MITRE ATT\&CK matrix to enable faster and more effective responses to cyber attacks. Based on a analysis of common cyber attack models, such as the Diamnond Model of Intrusion Analysis and the Lockheed Martin Cyber Kill Chain, the MITRE ATT\&CK matrix is used to develop an extended Kill Chain model. In this new model, MITRE tactics are grouped into five sequential attack phases, allowing for a clearer differentiation between actions taken during an attack. Aditionally, one ongoing group of MITRE tactics was identified. Building on this model, two graph-based representations are developed: a simple graph structure and a hierarchical, tree-shaped graph of MITRE tactics and techniques. The following discussion addresses the practical application of the new model, as well as potential further developments, such as integrating AI to analyse and predict existing and potential attack patterns.}, subject = {Computersicherheit}, language = {en} } @masterthesis{Reinhardt2024, type = {Bachelor Thesis}, author = {Reinhardt, Janek Simon}, title = {Untersuchung der Realisierbarkeit von Heartbeat-Monitoring in Wazuh}, publisher = {Technische Hochschule Brandenburg}, address = {Brandenburg an der Havel}, doi = {10.25933/opus4-3220}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:522-opus4-32204}, school = {Fachhochschule Brandenburg}, pages = {99}, year = {2024}, abstract = {Der Stellenwert der {\"U}berwachung der Sicherheit von IT-Systemen nimmt mit dem Voranschreiten der Digitalisierung immer weiter zu.

A major limitation regarding microscopic objects is spatial resolution, which is overcome by microscopes. Time resolution can be dealt with using either time-lapse or high-speed cameras. Finally, eyes only detect visible radiation within the wavelength range from about 380 nm to 780 nm. Changing the detected spectral range of electromagnetic radiation can dramatically enhance our vision.

In order to explain all uses of these waves in the food industry, the chapter begins with a general discussion of properties of waves and their description with wavelength frequency, speed of propagation, and also energy transport. Using visible light as starting point, electromagnetic waves in other wavelength regimes are discussed. The interaction of EM radiation with matter reveals that the wave description alone is insufficient to explain all observed phenomena. Understanding the attenuation of EM radiation in matter requires knowledge of the particle properties of electromagnetic waves, most easily summarized by the concept of photons which carry energy as well as momentum. This wave-particle duality does apply not only to EM waves, i.e. photons, but also to the particles which build up matter, in particular electrons, which also need to be described as waves. This leads to respective quantum mechanical explanations of the microscopic structure of matter in the form of atoms, molecules, and nuclei. Knowledge of their structure is a prerequisite to understand, first, the generation of EM radiation and, second, also its interaction with matter. As a result, it will become obvious that there are mostly three different usages of EM radiation in the food industry: preserving, characterizing, and heating.}, language = {en} } @misc{OPUS4-3250, title = {Jahrbuch 2023/2024 der Absolventinnen und Absolventen}, editor = {Wilms, Andreas}, publisher = {Technische Hochschule Brandenburg}, address = {Brandenburg an der Havel}, organization = {Technische Hochschule Brandenburg}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:522-opus4-32507}, pages = {92}, year = {2024}, language = {de} } @misc{OPUS4-3254, title = {Forschungs- und Transferbericht der Technischen Hochschule Brandenburg 2022/23}, editor = {Wilms, Andreas and Hirsch, S{\"o}ren}, publisher = {Technische Hochschule Brandenburg}, address = {Brandenburg an der Havel}, organization = {Technische Hochschule Brandenburg}, issn = {1861-3462}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:522-opus4-32541}, pages = {98}, year = {2024}, language = {de} } @inproceedings{FroschLindauerZuidhof2024, author = {Frosch, Katharina and Lindauer, Friederike and Zuidhof, Niek}, title = {Exploring the Digital Divide in Workplace Learning: A Rapid Review}, series = {ICDS 2024, The Eighteenth International Conference on Digital Society, Barcelona, Spain}, booktitle = {ICDS 2024, The Eighteenth International Conference on Digital Society, Barcelona, Spain}, publisher = {IARIA}, pages = {1 -- 6}, year = {2024}, abstract = {This article examines the digital learning divide in workplace learning, with an emphasis on the disparity in the distribution of advanced learning technologies (ALT) across different types of workplaces.

The flow has been considered to be radial, incompressible and laminar. The time-dependent Navier-Stokes equation has been solved in cylindrical coordinates using Fourier transform, and the oscillating flow velocity across the thickness of the cell has been obtained at different times. The flow velocity function in the unsteady state is related to the vertical component of the coordinates in the form of parabolic functions and also to the inverse of the radial component. The time dependence appears as a simple harmonic with a frequency equal to the oscillation frequency. The velocity of the flow is maximum at the middle of the cell along its height and gradually decreases from the middle towards the top or bottom plane and reaches zero. Pressure does not depend on the height and changes logarithmically with the radius. The dependence of pressure on time is also a simple harmonic with the external frequency, but it has a phase shift with respect to the velocity.}, language = {en} } @inproceedings{SoniNeubertDietrichetal.2023, author = {Soni, Jaykumar and Neubert, Tom and Dietrich, Benjamin and Vielhauer, Claus}, title = {Virtual Sessions for Forensic Analysis of Video Conferencing Systems: A Novel Methodology}, series = {Konferenz: IARIA SECURWARE 2023, the Seventeenth International Conference on Emerging Security Information, Systems and Technologies: Porto, Portugal}, booktitle = {Konferenz: IARIA SECURWARE 2023, the Seventeenth International Conference on Emerging Security Information, Systems and Technologies: Porto, Portugal}, publisher = {IARIA}, pages = {18 -- 20}, year = {2023}, language = {en} } @article{HascheKaraschewskiCreutzburg2023, author = {Hasche, Eberhard and Karaschewski, Oliver and Creutzburg, Reiner}, title = {iPhone12 imagery in scene-referred computer graphics pipelines}, series = {Electronic Imaging}, journal = {Electronic Imaging}, publisher = {Society for Imaging Science and Technology}, doi = {10.2352/EI.2023.35.3.MOBMU-350}, pages = {350-1 -- 350-14}, year = {2023}, abstract = {With the release of the Apple iPhone 12 Pro Max in 2020, various features were integrated that make it attractive as a recording device for scene-related computer graphics pipelines.

Among new photodetector types are photosensitive structures based on cascade concentrators, whose operational principle involves the absorption of optical radiation followed by its reemission at a longer wavelength and radiation concentration onto a highly efficient small-area photodetector. The absorption and re-emission spectra of each cascade layer depend on the characteristics of the material used. Сolloidal quantum dots are among the most promising materials for cascade layers due to their manufacturing technology, which provides for accurate control over the photoluminescence maximum position. It seems highly relevant to develop and to study photosensitive structures with cascade concentrators of various shapes based on CdS, CdSe/ZnS, and PbS colloidal quantum dots. Aim . To develop photosensitive structures with a wide-range sensitivity spectrum based on concentrators containing arrays of metal chalcogenide CQDs and to study their characteristics. Materials and methods . Cascade photosensitive structures were manufactured based on layers made of polymethyl methacrylate and layers of colloidal quantum dots embedded in a polystyrene matrix. Results . Three-layer concentrators were manufactured with different colloidal quantum dots in each concentrator layers. A 22 \% increase in the output power was observed for a three-layer cascade structure based on different cascade layer materials compared to a similar structure using a single layer concentrator. Conclusion . The conducted studies showed an increase in the efficiency of photosensitive structures with a cascade concentrator based on colloidal quantum dots of various types (CdS, CdSe/ZnS, and PbS) in the cascade layers.}, language = {ru} } @article{Vollmer2023, author = {Vollmer, Michael}, title = {So weit das Auge tr{\"a}gt}, series = {Physik in unserer Zeit}, volume = {54}, journal = {Physik in unserer Zeit}, number = {5}, publisher = {Wiley}, issn = {1521-3943}, doi = {10.1002/piuz.202301675}, pages = {222 -- 230}, year = {2023}, abstract = {Sichtweiten in der Atmosph{\"a}re reichen von wenigen Metern im Nebel bis zu einigen hundert Kilometern bei extrem guten Fernsichtbedingungen.

While doing our research in two different countries, we distinguish between commercial and non-commercial organizations as well as add an international perspective. Based on an acknowledged European skills framework, we focus our study on such soft skills as teamwork, communication, and conflict management and use recognized surveys to quantify them. We use a well-known Gallup methodology to evaluate employee engagement. Using correlation analysis, we investigate the impact of the three selected skills on employee engagement while considering the organization type and country, factors that may play an important role in the digital transformation of businesses and companies.}, language = {en} } @article{MansoorSchwarzCreutzburg2023, author = {Mansoor, Nazneen and Schwarz, Klaus and Creutzburg, Rainer}, title = {Importance of OSINT/SOCMINT for modern disaster management evaluation - Australia, Haiti, Japan}, series = {Electronic Imaging}, volume = {35}, journal = {Electronic Imaging}, number = {3}, publisher = {Society for Imaging Science and Technology (IS\&T)}, doi = {10.2352/EI.2023.35.3.MOBMU-354}, pages = {354-1 -- 354-14}, year = {2023}, abstract = {Open-source technologies (OSINT) and Social Media Intelligence (SOCMINT) are becoming increasingly popular with investigative and government agencies, intelligence services, media companies, and corporations.

This PoC work combines the open data from Reddit and the part of the state-of-the-art BERT model. Using the PRAW Python library, the project fetches comments and posts of users. Then these texts are converted into a feature vector - representation of all user posts and comments. The main idea here is to create a comparable user's pair similarity score based on their comments and posts. For example, if we fix one user and calculate scores of all mutual pairs with other users, we will produce a total order on the set of all mutual pairs with that user. This total order can be described as a degree of written similarity with this chosen user. A set of "similar" users for one particular user can be used to recommend to the user interesting for him people. The similarity score also has a "transitive property": if \$user_1\$ is "similar" to \$user_2\$ and \$user_2\$ is similar to \$user_3\$ then inner properties of our model guarantees that \$user_1\$ and \$user_3\$ are pretty "similar" too. In this way, this score can be used to cluster a set of users into sets of "similar" users. It could be used in some recommendation algorithms or tune already existing algorithms to consider a cluster's peculiarities. Also, we can extend our model and calculate feature vectors for subreddits. In that way, we can find similar to the user's subreddits and recommend them to him.}, language = {en} } @article{SkylarSchwarzCreutzburg2023, author = {Skylar, Artem and Schwarz, Klaus and Creutzburg, Reiner}, title = {Practical OSINT investigation in Twitter utilizing AI-based aggressiveness analysis}, series = {Electronic Imaging}, volume = {35}, journal = {Electronic Imaging}, number = {3}, publisher = {Society for Imaging Science and Technology (IS\&T)}, doi = {10.2352/EI.2023.35.3.MOBMU-355}, pages = {355-1 -- 355-15}, year = {2023}, abstract = {Open-source intelligence is gaining popularity due to the rapid development of social networks.

PSP is the estimation of the 3D structure of a protein, generally through deep learning architectures. Information about the geometry of the protein chain has been proven to be crucial for accurate predictions of 3D structures. However, this information is usually flattened as machine learning features that are not representative of the geometric nature of the problem. Leveraging recent advances in geometric deep learning, we redesign the 3D projector part of a PSP architecture with the addition of CGENN layers . CGENNs can achieve better generalization and robustness when dealing with data that show rotational or translational invariance such as protein coordinates, which are independent of the chosen reference frame. CGENNs inputs, outputs, weights and biases are objects in the Geometric Algebra of 3D Euclidean space, i.e. G3,0,0, and hence are interpretable from a geometrical perspective. We test 6 approaches to PSP and show that CGENN layers increase the accuracy in term of GDT scores by up to 2.1\\%, with fewer trainable parameters compared to linear layers and give a clear geometric interpretation of their outputs.}, language = {en} } @inproceedings{MarkgrafDietrichMuelleretal.2023, author = {Markgraf, Klaus and Dietrich, Benjamin and M{\"u}ller, Katja and Flassig, Robert and Flassig, Peter}, title = {FINEconcepts - Wissenstransfer und Energiesystemoptimierung mithilfe des digitalen Zwillings}, series = {NWK, HS Harz, 2023}, booktitle = {NWK, HS Harz, 2023}, publisher = {HS Harz}, pages = {428 -- 435}, year = {2023}, abstract = {Climate change, but also geopolitical circumstances, are moving topics such as energy efficiency and renewable energies more and more into the focus of the population, economy , and politics.

Using a discretization of the terminal density, we write these integral equations as a system of linear equations. We show that the kernel matrix of this system is, in general, ill-conditioned, so that it cannot be solved for the discretized density using a naive approach. Instead, we construct a sparse model for the kernel matrix using singular value decomposition (SVD), which allows us not only to systematically improve the condition number of the kernel matrix, but also determines the computational effort and accuracy of our method. In order to allow for the treatment of realistic inputs that may contain arbitrage, we reformulate the system of linear equations as an optimization problem, in which the SVD-transformed density minimizes the error between the input prices and the arbitrage-free prices generated by our method. To further stabilize the method in the presence of noisy input prices or arbitrage, we apply an 𝐿1-regularization to the SVD-transformed density. Our approach, which is inspired by recent progress in theoretical physics, offers a flexible and efficient framework for the arbitrage-free interpolation of plain-vanilla option prices and implied volatilities, without the need to explicitly specify a stochastic process, expansion basis functions or any other kind of model.
