The Dublin Airport Authority has said it could take around two months to address an outstanding security issue uncovered by a European audit.
The DAA are reiterating that it does not affect the screening of passengers or their luggage at Dublin Airport.
They said they are working with the Department of Transport to resolve the problem.
Minister for Transport Leo Varadkar said: "The Commission found two deficiencies during the audit at Dublin and, as a result, is imposing some additional security procedures on aircraft departing from Dublin and arriving into other EU airports.
"The first matter has been resolved. The other is technical in nature and does not affect passenger screening or baggage handling at the airport. Dublin Airport will adopt back-up procedures to address this second matter in the short term, while a longer term solution is implemented, and the security of the airport is maintained.
The Minister claimed the additional procedures are not expected to have any significant impact on passengers at the airport unless they are transferring through another EU airport en route to their final destination, in which case they will be required to undergo screening again.
Management at Dublin is also pointing out that Cork and Shannon airports are not affected.
Mr Varadkar said: "This does not impact on other airports in the State.
"I take these findings by the EU Commission very seriously and have taken steps to ensure that any deficiencies are rectified swiftly. I have met with officials from both my own Department and from the DAA, and I visited the airport on Monday. Immediate steps have now been taken.
"I cannot provide further detailed information on the audit findings, or respond further publicly on security grounds. However, I can assure that every effort is being made to enhance the measures in place to ensure they fully meet all EU requirements. "
