Permissions in Drupal are a set of rules that determine who can access and modify certain parts of the website. They are used to control access to content, features, and functions. Permissions are assigned to roles, which are then assigned to individual users. This allows administrators to control who can view, edit, and delete content, as well as who can access certain features and functions.

In Drupal, permissions are managed through the User Permissions page. This page allows administrators to assign permissions to roles, as well as to individual users. Permissions can be assigned to roles, which are then assigned to individual users. This allows administrators to control who can view, edit, and delete content, as well as who can access certain features and functions.

Permissions are an important part of Drupal's security system. By assigning permissions to roles and users, administrators can ensure that only those with the appropriate permissions can access and modify certain parts of the website. This helps to protect the website from malicious users and hackers.
