A security sandbox is an isolated environment that restricts the execution of code or applications to prevent them from affecting the rest of the system. In cybersecurity, sandboxes are used to safely run untrusted programs, analyze malware, or test new software without risking the integrity of the host device. For example, Android uses a security sandbox to ensure that each app operates in its own space, preventing unauthorized access to other apps’ data. This isolation mechanism is crucial for maintaining privacy and security, as it limits the potential damage from malicious or faulty software by confining their actions within a controlled boundary.
