What does "system interconnectivity" refer to in the context of SCAs?

"System interconnectivity" in the context of Security Control Assessors (SCAs) refers specifically to how systems interact with each other. This concept encompasses the various ways that different systems can communicate, share data, and collaborate to achieve functionality within a larger operational framework. Understanding interconnectivity is crucial for SCAs because it impacts security posture, risks associated with data sharing, and overall system vulnerability.

When systems are interconnected, safeguarding one system often entails considering the security measures of interconnected systems as vulnerabilities may propagate across connections. Therefore, SCAs must assess not only individual systems but also the implications of their interconnections to ensure comprehensive security assessments are conducted. The awareness of how systems interact helps in identifying potential threat vectors that could compromise the integrity of the overall environment.
