#### 3.2.3 Impact Enumeration
This diverse range of attack types underlines the complexity of the threat landscape and the need for a comprehensive security strategy that addresses different attack paths. By analyzing the distribution of attack scenarios by specific attack types, security professionals can gain valuable insight into the areas that require immediate attention and prioritization. For instance, the high prevalence of _Impersonation_ attacks may result in the need to implement multi-factor authentication, secure communication protocols, and rigorous identity management practices. The chart serves as a valuable tool for risk assessment and resource allocation. Higher-frequency attack types may warrant greater investment in security controls, incident response planning, and employee training to improve the overall resilience of the system against these threats. **Results Overview:** Our analysis of the obtained results addresses several critical issues regarding the security landscape of the system. The largest number of components observed in the attack scenarios is five: _FleetController_, _RemoteController_, _HX01_, _HxRemoteOperator_, and _SiteServer_. Further investigation shows that the system can be exposed to attacks through a variety of attack types, with 8920 cases in total. For a deeper analysis, we investigate specific attack scenarios based on different parameters. For example, we find that there are 397 attack scenarios with four components

This analysis can provide valuable insights when attack scenarios with different initial and final components are examined. For instance, in _Inpersonation_ attack scenarios with _HxRemoteOperator_ as the initial component and _SiteServer_ as the final component, a population of 288 attack scenarios is identified when five components are considered, while only one scenario appears when two components are considered. Similar patterns emerge when we extend this analysis to the _Unauthorized Access_ attack type, with the size of the population varying depending on the number of components and configurations. As mentioned earlier, our investigation involved a thorough analysis of 3100 scenarios in the provided case study, each of which has a different number of components. While configurations with different component counts provide valuable insights, scenarios with higher component counts, such as 4 or 5, reveal complicated interactions between components and potential attack paths. On the other hand, simpler scenarios consisting of 2 or 3 components are less comprehensive but easier to handle. More detailed results can be found in Tables 2 and 3, which provide a comprehensive overview of our analysis of the results. Table 2 outlines the frequency and characteristic features of various attack scenarios. Each row corresponds to a scenario with a different number of components, providing insight into the complexity and diversity of these scenarios. This table provides a comprehensive overview of the distribution and characteristics of attack scenarios, enabling in-depth understanding of potential security vulnerabilities. In parallel, Table 3 provides a comprehensive representation of the distribution of attack types based on the complexity of the scenarios. The table illustrates the distribution of different attack types of scenarios with a component count of 2 to 5, providing valuable insights into the prevalence of certain attack types at the different complexity levels of the scenarios.
