This detailed insight is critical for understanding evolving cyber threats and developing robust security solutions.

4. Protection from Zero-Day Exploits

Zero-day vulnerabilities pose significant risks as they are often unknown to software developers or security teams. Sandboxing helps mitigate the impact of these exploits by isolating potentially dangerous applications or processes. Even if a zero-day attack occurs, the sandbox prevents it from compromising the entire system, limiting the damage.

5. Prevents Unauthorized Access

Sandboxes provide an additional layer of protection by preventing unauthorized access to system resources. For example, many mobile applications are sandboxed, ensuring they can only access data within their own environment. This restriction helps prevent unauthorized apps from accessing sensitive information, reducing the likelihood of data breaches.
