What terms are often used to describe the relationship between a sub-directory and the directory...

Directories are commonly organized in a hierarchical structure, where each directory can contain sub-directories and files. In this hierarchy, the directory that contains another directory is referred to as theparent, and the contained sub-directory is referred to as thechild. This parent–child relationship is foundational to how file systems and many directory services represent and manage objects, including how paths are constructed and how inheritance can apply.

From a cybersecurity perspective, understanding parent and child relationships matters because access control and administration often follow the hierarchy. For example, permissions applied at a parent folder may be inherited by child folders unless inheritance is explicitly broken or overridden. This can simplify administration by allowing consistent access patterns, but it also introduces risk: overly permissive settings at a parent level can unintentionally grant broad access to many child locations, increasing the chance of unauthorized data exposure. Security documents therefore emphasize careful design of directory structures, least privilege at higher levels of the hierarchy, and regular permission reviews to detect privilege creep and misconfigurations.

The other options do not describe this standard hierarchy terminology. “Primary and Secondary” is more commonly used for redundancy or replication roles, not directory relationships. “Multi-factor Tokens” relates to authentication factors. “Embedded Layers” is not a st
