Ministers from Britain, France, Germany, Italy, Spain and Poland will also tackle illegal immigration and organised crime during their informal meetings on Wednesday and Thursday in Stratford-upon-Avon, Britain's Home Office said.
The Home Office said in a statement accompanying the agenda for the closed-door discussions that the so-called G-6 ministers aim to "share ideas and best practice" in the areas of terrorism, immigration and crime.
However, it stressed the G-6 is not a formal decision-making body, despite criticism from some politicians that they set the tone for EU-wide security policy in virtual secrecy.
Britain's Home Secretary John Reid and his five counterparts will gather around 4:00 p.m. (1500 GMT) on Wednesday to discuss the current terrorist "threat and what can be done to pre-empt the next attack," according to the agenda.
An hour later, they are set to discuss how to challenge "extremist ideas and ideals, including through dialogue with Muslim communities," it said.
During a dinner at Warwick Castle, north of Stratford-upon-Avon, in west central England, the group will discuss ideas on improving EU capacity in "policing and effective law-enforcement in weak states."
On Thursday, the last day, the ministers will discuss how to shut off illegal immigration routes and how to work with unspecified third countries to control migration flows.
They will also debate how to reduce the harm caused by organised crime, including value added tax fraud and trafficking of drugs and people before a closing press conference is given at 12:30 p.m. (1130 GMT).
