Authorization is usually performed by checking the authenticated user has the appropriate permissions to access the page they are trying to visit The permission check can be as simple as ensuring that a user has in fact signed in but can also be very sophisticated involving checks about the user s roles, group, or even which computer the user is accessing the web site from In this chapter, you ll start off by looking at how Pylons handles private data before learning how to implement a basic security system from scratch You ll then move on to considering an authentication and authorization tool called AuthKit and looking at its main features In the next chapter, you ll use the knowledge you ve gained about AuthKit in this chapter to add a sign-in form and role-based permissions system to the SimpleSite application..

Going through and rewriting all your string manipulation code might be a lot of work, and you might be wondering if there is some way around it. Rewriting your code might be a reasonable approach, but it might introduce new bugs or not handle all of the existing bugs correctly. There are some additional solutions that can help you insulate your code against many (but not all) types of buffer overflow attacks in a quicker way.

The easiest way to prevent any user from accessing a controller action is to make that action private. You ll remember from 9 that Pylons treats any controller method that starts with an underscore (_) character as private and will not dispatch to it as a controller action. This means controller methods beginning with _ are not directly publicly accessible. Let s create a controller to demonstrate this. Run the following commands to create a test project; you won t need SQLAlchemy or Google App Engine support:

png" ), QStringList() ); // Verify that we have one image and get the id for it QList<int> ids = cgetIds( QStringList() ); QCOMPARE( idscount(), 1 ); int id = ids[0]; // Add one tag, total one caddTag( id, "Foo" ); QCOMPARE( cgetTags()count(), 1 ); // Add one tag, total two caddTag( id, "Bar" ); QCOMPARE( cgetTags()count(), 2 );.

StackGuard is a compiler technique developed by Crispin Cowan. StackGuard inserts a canary just before the return address on the stack, and some additional code that checks that the canary is not corrupted just before a function returns. Microsoft has also incorporated a similar canary-like feature in its C++ compiler, which can be enabled by compiling with a /GS flag on the compiler s command line.

// Add one tag, total three c.addTag( id, "Baz" ); QCOMPARE( c.getTags().count(), 3 ); // Add a duplicate tag, total three c.addTag( id, "Foo" ); QCOMPARE( c.getTags().count(), 3 ); // Try to add a tag to a nonexisting id QEXPECT_FAIL("", "The tag will be added to the non-existing image.", Continue); c.addTag( id+1, "Foz" ); QCOMPARE( c.getTags().count(), 3 ); // The ImageConnection adds a database that we close here QSqlDatabase::removeDatabase( QLatin1String( QSqlDatabase::defaultConnection ) ); }

class ExampleController(BaseController): def hello(self): return self._result() def _result(self): return 'Hello World!' If you start the server and visit http://localhost:5000/example/_result, you will be shown a 404 Not Found error document, but if you visit http://localhost:5000/example/hello, you will see the Hello World! message because the public action hello() is able to return the value from the private method _result().

The next test case, which is shown in Listing 16-24, checks that the image storage and retrieval mechanisms work and are implemented in the testImages slot. The test procedure is very simple: Add an image to the database (tests addImage), make sure it is there (tests getIds), retrieve it (tests getImage), and compare it with the original image. One final test, which has been commented out, attempts to retrieve an image using an invalid id. This results in a call to qFatal in the ImageCollection class, and the application will end even if you call QTest::ignoreMessage(QString). The ignoreMessage can otherwise be handy to avoid showing expected warning messages emitted using qDebug or qWarning. Listing 16-24. Testing storing and retrieving images void ImageCollectionTest::testImages() { ImageCollection c; QCOMPARE( c.getIds( QStringList() ).count(), 0 ); QImage image( "test.png" ); c.addImage( image, QStringList() ); // Verify that we have one image and get the id for it QList<int> ids = c.getIds( QStringList() ); QCOMPARE( ids.count(), 1 ); int id = ids[0]; QImage fromDb = c.getImage( id ); QVERIFY( pixelCompareImages( image, fromDb ) );
