What is the focus of system security analysis?

The focus of system security analysis lies primarily in assessing system vulnerabilities to security threats. This process involves a thorough examination of the system's architecture, components, and operational procedures to identify areas where potential security threats could exploit weaknesses. By doing so, organizations can determine how secure their systems are and what measures need to be implemented to mitigate risks. This analysis is crucial in protecting sensitive data and maintaining the integrity and availability of systems in the face of evolving security challenges.

The other options do not align with the specific focus of system security analysis. Identifying management strategies for system performance, evaluating financial forecasts, and improving user interface design are all important aspects of systems engineering or project management but do not specifically address the vulnerabilities and threats that system security analysis aims to mitigate.
