Filesystem Security
Noun · Security & Infosec
Definitions
The protection of files, directories, metadata, and mount behavior through permissions, ownership, encryption, auditing, and safe configuration. Filesystem security is fundamental because many higher-level controls fail if local file access is too permissive.
In plain English: Protecting files and directories from unauthorized access or tampering.
Example: "The container escape became serious because filesystem security on the host allowed access to sensitive mounts."
