Best practice has been since decades for NATO and affiliated Air Forces to warn intruders and accompany them out of the violated air space. Only if they don't comply with this, escalation would happen, e.g. forcing to land and/or firing warning shots. Shooting down would be very last resort if they don't turn away and are not compliant at all.
Shoot first, ask then is more best practice in 'less civilised' parts of the world or where military exchanges are normal part of politics.
