I speak from memory about 1 year ago.
At 1 am (the time I got to the airport) the security area was closed. There were many people sleeping on the floor inside the airport. At around 4 am the security area reopened. The cleaners started work around this time, so those who were still sleeping were woken up.
Anyway, there was a 24 hour bar pre-security, located just outside the toilets.
