\chapter{Conclusions}
The aim of this research was to provide an understanding of the use of visualizations in cybersecurity and to identify the current state of the art, the real-world effectiveness and limitations of the tools developed and used in this field. To achieve this, a mixed-methods approach was used, combining a systematic review of the literature and a practical test of available visualization tools.

The systematic review of the literature revealed that visualizations have been widely used in cybersecurity to support various tasks such as threat detection, forensic investigation, and network analysis and showed how there is currently a steadfast research support and ongoing innovation in the field, particularly concerning the development of new methodologies and and the adoption of user-design methodologies. The analysis of the literature has also enabled the identification and definition of ideal objectives for security visualization, which can be summarized as providing an in-depth understanding of security data, detecting and responding to security incidents, effectively communicating security information, supporting decision-making, and enhancing security awareness among users and system operators.

In addition to the literature analysis, a practical analysis was also conducted, selecting the available solutions encountered during the review to evaluate their actual effectiveness in handling security data. Furthermore, proprietary tools from the current real-world scenario were selected to enable a comparison between the two approaches.

The results of the study showed that visualizations can be effective in enhancing cybersecurity by providing insights into complex data and facilitating decision-making spanning across various fields within the realm of security. However, the comparison with proprietary tools has highlighted that the latter are still preferable in terms of adoption. This preference stems from the prototypical nature of the majority of solutions encountered in the research, as well as the potential dedicated support and services that these proprietary solutions can offer. Furthermore, it was possible to highlight how current solutions in the market do not leverage the research findings in terms of innovative visualization methodologies, indicating the potential for improvements derived from such research.

The study also identified several limitations and challenges associated with the use of visualizations in cybersecurity, such as the lack of standardization and evaluation of visualizations and the disparity of solutions towards different types of end users. Following this, a possible implementation of a development framework was provided, obtained through a refinement of a previously presented framework, pointing out the various steps that as a result of the review showed critical issues and need for improvement.

Overall, the methodology used in this research explores the possibilities of security visualization and enumerates its various gaps and limitations. The obtained results can be leveraged to enhance the design and development of applications aimed at improving the security of computer systems and networks.

\section{Future Works}
The conducted study has identified several areas of interest where further research and the development of solutions are needed to address the identified gaps. The need to promote information exchange in security among users at the same level, as well as among different types of end users, emerged as one of the main gaps identified during the conducted research, based on the analyzed studies and received feedback. In this regard, it would be beneficial to explore the various possibilities offered by the tools considered in this study and propose the development of a methodology or solution aimed at addressing this gap. 

Given the large percentage of tools in the prototype state encountered, it would be useful to start with one of the proposed solutions and refine it through the framework produced in this work, so as to propose a solution that can be used in a real-world context and evaluate its actual functionality and efficiency through a broader evaluation than those conducted and cited. This would provide actual evidence of the contribution of security visualization techniques. Simultaneously with this approach, it would be possible to develop a new type of solution, using the framework produced and proposed in this work, in order to verify its validity.

Another interesting field of application is definitely is the investigation on how visualizations can be utilized in the context of cybersecurity awareness training. Conducting a study to assess the effectiveness of visualizations in conveying complex cybersecurity concepts in an accessible and engaging manner to learners, thereby enhancing their understanding and awareness of digital threats, is an aspect undervalued by current research, but potentially significant.
