2	Visualization Of Cyber Threats : Visualization To Leading Operatives During Cybersecurity exercises Tysk, Gustaf January 2023 (has links) The increasing dependence on digital infrastructure leaves individuals, societies and even nations vulnerable in the case of a cyberattack. To prepare for threats and attacks, cyberattacks be simulated in environments called cyber ranges. CYBER RANGE AND TRAINING ENVIRONMENT (CRATE), Sweden's cyber range, is an example of such an environment. This environment is sophisticated and complex, but challenges remain for the operatives in how to interpret the multitude of information items that are produced during a simulation. An emerging field of study is the study of situational awareness in the cyber domain, which describes how an operative can render an accurate mental picture, which enables for quick assessment and decision-making in a situation where a multitude of data or information items are involved. An integral part of situational awareness is effective visualization. Visualization can form the linkage in the human-computer interaction and has been demonstrated in other industries and fields to facilitate situational awareness. However, the linkage between situational awareness and visualization in the unique context of a cyber range was a new topic of study. This thesis aim was to provide insight and advance the knowledge of visualization for situational awareness in the unique context of the cyber range CRATE. Conclusively, in the development of a visualization software, the abstraction levels and time frame of the information items collected should be considered. Each information item is of different relevance depending on both the operative's role and in which time frame through which the information is analyzed. A visualization technique that recognizes the abstraction level and the time frame increases the situational awareness for the operative conducting the simulation because it renders both an estimation of critical core processes, current events that are unfolding and enables for the future projection of events.

3	Social Media Usage among First Responders to Hurricane Harvey Spinuzzi, Lacey Cook 05 1900 (has links) Social media plays an important role during multiple phases of a disaster. While it is widely known that citizens turn to social media during disasters to gain information and send help requests, there is a significant gap in our knowledge of how, or if, first responders use social media to conduct disaster response operations. To help address this gap this study employed qualitative, semi-structured interviews with a sample of first responders (N = 20) who were deployed to Hurricane Harvey in 2017. The interviews sought to gain a better understanding of how social media was used to conduct response operations and identify both limitations and advantages of social media as perceived by first responders. Through a systematic coding process the analysis identified four themes related to social media usage among first responders to disasters: (1) more than just Twitter; (2) rumor has it; (3) one size does not fit all; and (4) timing is everything. The findings of this research highlight the importance of social media for both organizations and individuals involved in responding to disasters. social media first responders Hurricane Harvey disaster communication crisis communication crisis informatics common operational picture Sociology, General
4	The effective use of multiple unmanned aerial vehicles in surface search and control Berner, Robert Andrew 12 1900 (has links) Approved for public release; distribution in unlimited. / This study analyzes the effective use of multiple unmanned aerial vehicles (UAVs) for the Navy's Surface Search and Control mission. In the future, the Navy hopes to leverage the capabilities of a family of UAVs to provide increased situational awareness in the maritime environment. This family of UAVs includes a Broad Area Maritime Surveillance (BAMS) UAV and Vertical Take-Off UAVs (VTUAVs). The concepts of operations for how these UAVs work together have yet to be determined. Questions exist about the best number of UAVs, types of UAVs, and tactics that will provide increased capabilities. Through modeling and agent-based simulation, this study explores the validity of future UAV requirements and provides insights into the effectiveness of different UAV combinations. For the scenarios modeled, the best UAV combination is BAMS plus two or three VTUAVs. However, analysis shows that small numbers of VTUAVs can perform as well without BAMS as they do with BAMS. For combinations with multiple UAVs, BAMS proves to be a valuable asset that not only reduces the number of missed classifications, but greatly improves the amount of coverage on all contacts in the maritime environment. BAMS tactics have less effect than the mere presence of BAMS itself. / Lieutenant, United States Navy Drone aircraft Military surveillance Naval tactics Sea control Unmanned Aerial Vehicles UAVs Agent-based modeling MANA Surface Search and Control Surface Surveillance Coordination SSC Broad Area Maritime Surveillance BAMS VTUAV Common Operational Picture
5	Förståelse vid krishantering Wedebrand, Christoffer January 2017 (has links) Studiens syfte är tvåfaldigt. Dels är syftet att undersöka hur organisationers förståelse (i meningen deras lägesbild och situationsförståelse) och handlande tycks förhålla sig sinsemellan. Dels är syftet att undersöka hur organisatoriska skillnader tycks påverka förståelsen (återigen i meningen deras lägesbild och situationsförståelse). I båda fallen inom sammanhanget av samhällelig krishantering. Studiens forskningsfrågor besvaras genom en kombination av kvalitativa metoder. Det empiriska materialet utgörs av intervjuer med personal inom somliga av de räddningstjänster som inblandades i hanteringen av en omfattande skogsbrand på Gotland, våren 2016.
