+This article explains how `SfPdfViewer` handles secured PDF documents, including password-protected files and documents with permission restrictions. It describes expected behavior when opening secured files. It links to task-focused guides for implementation details.
 
 The PDF specification defines two common security configurations:
 
 - [Password-protected documents](./document-security/password-protected) — a password is required to decrypt and open the file.
 - [Permission-restricted documents](./document-security/permission) — an owner password sets granular permissions such as printing, copying, editing, annotating, and form filling.
 
-Behavior and expectations:
+### Behavior and expectations
+
 - When a password-protected PDF is loaded, the viewer prompts for the password. If the password is incorrect or omitted, the document does not open.
-- For permission-restricted PDFs, the viewer reads and enforces the document’s security flags. Disallowed actions (for example, print, copy, or annotate) are disabled in the UI and blocked through APIs.
+- For permission-restricted PDFs, the viewer reads and enforces the document's security flags. Disallowed actions (for example, print, copy, or annotate) are disabled in the UI and blocked through APIs.
+
+The viewer enforces the following document permission flags:
+
+- **Print**: when disallowed, the print action is not available.
+- **Copy**: when disallowed, copy commands are disabled and text selection may be limited.
+- **Edit / Modify content**: when disallowed, content editing actions are not available.
+- **Annotate**: when disallowed, the annotation toolbar and related actions are disabled.
+- **Form filling**: when disallowed, form fields are read-only.
