The Sitecore Security Editor is a primary tool for managing permissions on items and their descendants. It allows administrators and developers to explicitly set standard access rights such as Read (view an item) and Write (modify an item). A core concept within the Security Editor is managing Inheritance. By default, items inherit security settings from their parent. The editor's interface is designed to visualize and override this inheritance by setting explicit "allow" or "deny" permissions, thereby directly managing how inheritance is applied to a specific role for a given item.

B. Debug: While "Debug" is a valid, specific access right in Sitecore, it is not one of the standard, columnar permissions managed directly within the main Security Editor interface for every item.

C. Access: "Access" is a general concept representing the outcome of applied permissions, not a specific, configurable permission that can be assigned within the Security Editor.

1. Sitecore XM Cloud Documentation, Security, The access rights: This document lists the standard access rights that can be assigned to items. It explicitly mentions "Read" and "Write" among the primary rights. It states, "The following access rights can be assigned to every item in a Sitecore installation: Read, Write, Rename, Create, Delete, Administer."

2. Sitecore XM Cloud Documentation, Security, Security permissions: This page details the visual representation of permissions within security tools. It explains the icons for "Allow," "Deny," and "Inheritance," confirming that managing the inherited state of a permission is a fundamental interaction. It describes the grayed-out state as "Permission is inherited," which users can change to an explicit state.

3. Sitecore XM Cloud Documentation, Security, The Security Editor: This document provides an overview of the tool, stating, "In the Security Editor, you can grant or deny roles and users access rights to the items in the content tree." The interface it presents is built around managing the standard rights and their inheritance.
