What does 'System Isolation' mean?

System isolation is the practice of segregating a system, application, or component from others to ensure security, stability, and performance. This approach minimizes the risk of interference, such as unauthorized access, resource conflicts, or cascading failures, by creating controlled environments for specific processes or workloads. In IT and cybersecurity, system isolation is often used during incident response to contain threats, such as malware or network breaches, preventing them from spreading to other parts of the system. It can also be implemented for testing new software in a sandbox environment without impacting production systems. By limiting interactions and dependencies, system isolation enhances security, simplifies troubleshooting, and maintains system integrity.
