The DAA says an internal review is underway after a man boarded a flight without ID or a boarding pass.
The 48-year-old managed to make it through security and onto a plane for Birmingham on Monday night.
But he was then removed and brought to court.
The DAA says it notes the speedy apprehension of the individual by airport police and says an interal review is under way
Transport Minister Eamon Ryan says it will be investigated.
"In any instance where someone gets through without showing a passport, without showing a boarding pass, clearly it's of concern.
"And we'll be discussing with Dublin Airport how they can further tighten the arrangements so that that doesn't happen."
Aviation journalist Eoghan Corry from Air and Travel Magazine says security may be increased as a result.
"Hugely embarrassing for the airport.
"And people will remember the big security queues [and] the problems that we had last summer.
"What inevitably happens out of an event like this is that the security will be upscaled and that that will mean extra checks on everybody going through.
"So it could cause security queues to slow down a little."
