immutable linux

Immutable Linux configurations employ read-only file systems and filesystem-level immutability attributes to protect essential binaries, libraries, and configurations from alteration or tampering.

This approach enhances system security by preventing unauthorized or accidental changes, reducing the attack surface for malware and misconfigurations, and ensuring a consistent baseline environment.

Common use cases include embedded systems, immutable infrastructure in cloud deployments, and container base images with read-only layers. Updates are applied via atomic image replacements or specialized tooling to preserve immutability guarantees.
