But this requires a certain amount of restraint on the part of the designers of the respective setting and at the same time seems to require a full disclosure of the underlying theoretical and aesthetic concepts to the participants, if the participants are really to be taken seriously and given the means to actually be able to become creative themselves in an understandable way within the given context. In this paper, the consequences of such a demand are first discussed theoretically. Finally, for the concept developed by the author, "Every human being can compose on the basis of natural numbers", an attempt is made in this specific case to determine in what form such a concept could be passed on in order to meet the above criteria.}, language = {en} } @misc{OPUS4-3211, title = {Forschungsbericht der Fachhochschule Brandenburg 2013 - 2014}, editor = {Wieneke-Toutaoui, Burghilde and Fischer, Arno}, address = {Brandenburg an der Havel}, organization = {Fachhochschule Brandenburg}, issn = {1861-3462}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:522-opus4-32112}, pages = {216}, year = {2015}, subject = {Fachhochschule Brandenburg}, language = {de} } @masterthesis{Schwabe2024, type = {Bachelor Thesis}, author = {Schwabe, Carina}, title = {Derivation of a technical representation of the MITRE ATT\&CK matrix and further analyses of the kill chain}, publisher = {Technische Hochschule Brandenburg}, address = {Brandenburg an der Havel}, doi = {10.25933/10.25933/opus4-3215}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:522-opus4-32152}, school = {Technische Hochschule Brandenburg}, pages = {46}, year = {2024}, abstract = {In modern societies, technology has a high value, as nearly all systems are controlled by information technology. 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. Um diese Aufgabe zu vereinfachen werden Monitoring-Systeme eingesetzt. Diese sammeln und verarbeiten Daten, um den Status des IT-Systems zu ermitteln. Zu diesen Monitoring-Systemen z{\"a}hlt Wazuh, welches in der Lage ist, die "Integrit{\"a}t" und "Vertraulichkeit" unter Zuhilfenahme von Agenten zu {\"u}berwachen. Damit deckt Wazuh lediglich zwei der drei Schutzziele der IT-Sicherheit ab. Aus diesem Grund wird in dieser Bachelorarbeit untersucht, auf welche Art und Weise sich das SIEM und XDR System um Heartbeat Monitoring erweitern l{\"a}sst. Dadurch wird Wazuh bef{\"a}higt das dritte Schutzziel der IT-Sicherheit, die Verf{\"u}gbarkeit, zu {\"u}berwachen. Zu diesem Zweck wird eine Erweiterung der Wazuh-Implementierung um den Heartbeat Daemon des Elastic Stacks durchgef{\"u}hrt. Die Implementierung soll in der Lage sein, die Daten des Heartbeat Daemons zu empfangen, zu speichern, darzustellen und Benachrichtigungen auszul{\"o}sen, sobald sich der Status von {\"u}berwachten Systemkomponenten {\"a}ndert. Um die Funktionalit{\"a}t dieses Proof of Concepts zu {\"u}berpr{\"u}fen wird Heartbeat Monitoring ebenfalls in einem Vergleichssystem umgesetzt. Dabei handelt es sich um die native Umgebung des Daemons, den Elastic Stack. Die Funktionalit{\"a}t des Elastic Stacks konnte auf unterschiedlichen Wegen reproduziert werden. Dies erfolgt zum einen durch die direkte Verarbeitung der Heartbeat-Ausgabe durch Wazuh. Alternativ besteht die M{\"o}glichkeit, die Heartbeat-Daten direkt in Wazuhs Datenbank zu schreiben. In Abh{\"a}ngigkeit der Version des Heartbeat-Daemons ist die Verwendung von Logstash als Middleware erforderlich. Das Darstellen der Daten ist f{\"u}r beide Methoden in Wazuhs Weboberfl{\"a}che m{\"o}glich. Das Erweitern von Wazuh um Heartbeat Monitoring erm{\"o}glicht der Software die Abdeckung der relevantesten Schutzziele der IT-Sicherheit.
