+
+## Permission dependencies
+
+Feature policies can be quite complex and consist of multiple rules.
+Quite often, one permission can be based on another.
+
+Designing good permissions means reusing existing permissions as much as possible
+and making access to features granular.
+
+In the case of a complex resource, it should be broken into smaller pieces of information
+and each piece should be granted a different permission.
+
+A good example in this case is the _Merge Request widget_ and the _Security reports_.
+Depending on the visibility level of the _Pipelines_, the _Security reports_ will be either visible
+in the widget or not. So, the _Merge Request widget_, the _Pipelines_, and the _Security reports_,
+have separate permissions. Moreover, the permissions for the _Merge Request widget_
+and the _Pipelines_ are dependencies of the _Security reports_.
+
+### Permission dependencies of Secure features
+
+Secure features have complex permissions since these features are integrated
+into different features like Merge Requests and CI flow.
+
+ Here is a list of some permission dependencies.
