Issue
- The admin wants to upload a document to the site, but he or she must limit other users from downloading the document and from taking screenshots of the document on that site.
Resolution
- This business-specific requirement is not fulfilled through any feature included in an out-of-the-box Liferay DXP 7.0
- However, unlike Service Builder, Liferay DXP's permissions framework is configured declaratively.
As a workaround, users can define all of their permission in an XML file called default.xml by convention. They can then implement permissions checks in the appropriate places in their code.
