Security panel
You can limit access to an Adobe PDF document when you export it. When files have
restricted features, any tools and menu items related to those features are dimmed. In Adobe
InDesign CS, the Security panel is consistent with the same panel in Adobe Illustrator CS
and Acrobat 6 Professional.
Note:
PDF export presets do not support passwords and security settings. If you export a
document that includes security, and click Save Preset from the Export PDF dialog box, the
passwords and security settings won’t be preserved.
Pass wor ds se c t ion
An Adobe PDF file can have an open document password (user password) and a change
security settings password (master password). If you set any security restrictions in your
file, you should also specify a master password; otherwise anyone who opens the file could
remove the restrictions. If a file is opened with a master password, the security restrictions
are temporarily disabled. If the file has both passwords, you can open it with either one.
