What is sandboxed execution? Constraining files, permissions, and networks
Understand process isolation, containers, read-only mounts, shared kernels, and network boundaries through unknown-script execution, with allowed and denied checks.
Understand the concept
Sandboxed execution runs programs with constrained resource access, using mechanisms such as containers and operating-system permissions. It is not one product or absolute security. Shared mounts and high privileges can expand impact. AI-tool restrictions must be enforced by runtimes rather than only instructions.
Actual configuration determines isolation
A text-processing sandbox can receive only needed inputs and mount originals read-only. A writable user-directory mount still permits changes. Test or sandbox names do not establish limited access.
Docker describes namespaces and control groups while containers share the host kernel. They are not full virtual machines or proof of zero host impact. This is architecture explanation without unknown-code or adversarial execution.
Control files, networks, and credentials separately
Write limits do not automatically prevent network sending, and network blocking does not protect all mounts. Check capabilities separately and avoid unnecessary credentials or inherited configuration for public-text scripts.
Docker rootless mode reduces host privilege requirements but does not eliminate every risk. Check environment support and limitations. Granting administrator access to fix startup can undermine intended isolation.
Validate both allowed and denied operations
Use harmless files to test permitted writes, denied outside writes, and expected networking. This is test design without permission changes. A successful normal script does not establish denial enforcement or accurate error reporting.
Inspect artifacts and retained data and limit cleanup to task paths. Review AI-generated scripts; sandboxing is one impact-control layer. Keep recovery methods and verify actual outcomes for important work.
