Example:

// Create a blank document, which has no security of any kind by default
Document doc = new Document();

// The "Security" property serves as a description of the security level of a document
Assert.assertEquals(doc.getBuiltInDocumentProperties().getSecurity(), DocumentSecurity.NONE);

// Upon saving a document after setting its security level, Aspose automatically updates this property to the appropriate value
doc.getWriteProtection().setReadOnlyRecommended(true);
doc.save(getArtifactsDir() + "Properties.Security.ReadOnlyRecommended.docx");

// We can open a document and glance at its security level like this
Assert.assertEquals(new Document(getArtifactsDir() + "Properties.Security.ReadOnlyRecommended.docx").getBuiltInDocumentProperties().getSecurity(),
        DocumentSecurity.READ_ONLY_RECOMMENDED);

// Create a new document and set it to Write-Protected
doc = new Document();

Assert.assertFalse(doc.getWriteProtection().isWriteProtected());
doc.getWriteProtection().setPassword("MyPassword");
Assert.assertTrue(doc.getWriteProtection().validatePassword("MyPassword"));
Assert.assertTrue(doc.getWriteProtection().isWriteProtected());
doc.save(getArtifactsDir() + "Properties.Security.ReadOnlyEnforced.docx");

// This document's security level counts as "ReadOnlyEnforced"
Assert.assertEquals(new Document(getArtifactsDir() + "Properties.Security.ReadOnlyEnforced.docx").getBuiltInDocumentProperties().getSecurity(),
        DocumentSecurity.READ_ONLY_ENFORCED);

// Since this is still a descriptive property, we can protect a document and pick a suitable value ourselves
doc = new Document();

doc.protect(ProtectionType.ALLOW_ONLY_COMMENTS, "MyPassword");
doc.getBuiltInDocumentProperties().setSecurity(DocumentSecurity.READ_ONLY_EXCEPT_ANNOTATIONS);
doc.save(getArtifactsDir() + "Properties.Security.ReadOnlyExceptAnnotations.docx");

Assert.assertEquals(new Document(getArtifactsDir() + "Properties.Security.ReadOnlyExceptAnnotations.docx").getBuiltInDocumentProperties().getSecurity(),
        DocumentSecurity.READ_ONLY_EXCEPT_ANNOTATIONS);
