Minister for Justice Simon Harris has spoken to Garda Commissioner Drew Harris and the Houses of the Oireachtas authorities following renewed concerns about the safety of politicians.
The development comes after bags of excrements were thrown at Minister for State Anne Rabbitte and Fine Gael TD Ciaran Cannon in Gort, Co Galway on Wednesday night.
Separately, Sinn Féin Justice spokesman Martin Kenny has said he is planning to move house following two separate attacks at his Co Leitrim home in recent years.
Minister Harris said he was reassured that An Garda Síochána is providing politicians with security advice and assistance.
While not commenting on any individual case, he said any attack on a public representative was "an attack on democracy".
He said any attack or assault will be treated "extraordinarily seriously" by the most senior levels of An Garda Síochána.
"The gardaí are very much aware of this issue," he added.
Minister Harris said Commissioner Harris was adamant that the ability of representatives to do their work on behalf of the people is vital.
"It is a core part of democracy that people can do their work safely and move around safely," he said.
Gardaí are expected to reissue advice to TDs and Senators regarding personal safety. Politicians had received information in the past but the advice will be updated and reissued.
Last year, Commissioner Harris met Ceann Comhairle Seán Ó Fearghaíl to discuss the safety and security of TDs and senators.
Minister Harris also spoke to the Houses of the Oireachtas authorities and reassured them of his support in any security measures they wish to take.
He said it was important that politicians knew that the gardaí were in a position to provide advice to any public representatives who had concerns about their security.
Meanwhile, Mr Kenny has said TDs and other public representatives should continue to be accessible to the public, despite threats being made by a small cohort of people.
Mr Kenny himself has been the subject of a number of incidents at his house in Co Leitrim, including in 2019 when his car was set alight outside his home.
Last year, a man was arrested after a vehicle crashed through the gates of his home during the middle of the night.

Speaking on RTÉ's Morning Ireland, he described the incident in Co Galway this week as "simply outrageous and a new low in the way people behave".
"If you have to resort to throwing things at people rather than civil discourse there is a clear problem from the outset," he said.
Mr Kenny said it is a dangerous direction as he described how some people are encouraging each other online to be disrespectful, ignorant and outrageous.
This has created an atmosphere where a small number of people attack members of the public and public representatives, he said.
Mr Kenny said the threats and attacks on himself and his family have caused huge trauma, as he referred to his safety being "violated a number of times".
He said he may have to change where he lives because of the action taken against him and his family by some people.
Elsewhere, Minister for Health Stephen Donnelly has described the incident in Galway as an act of "cowardice and an act of thuggery".
Mr Donnelly added: "We have to have open, frank and sometimes difficult debate in this country and everyone needs to be able to air their views, but those kinds of actions are just not acceptable.
"Matters of security are best addressed by the gardaí."
