Yeah, I don't think there's any easy answer to the issue of the refugees acting as a Trojan Horse, outside of severe restrictions which would clearly be inhumane.
Screening would create a constellation of camps that would surely act not only as breeding grounds for diseases but also as centers for radicalization, I think, unless it consisted of something so simple as a questionnaire (easily flouted) and fingerprinting -- I can't imagine background checks reaching into Syria and Iraq would be very useful.
Monitoring would probably be outside the scope of the resources available to the EU's security apparatus, and would likely entail the use of NSA-style techniques which they have so recently and rightfully castigated.
