Brazilian Grand Prix organisers have been issued with suggested revised security procedures after an array of incidents at this year's event.
Safety has been an underlying concern for several years but a sequence of attacks took place on Formula 1 personnel at Interlagos, when paddock members were returning to their hotels.
The most serious took place on the Mercedes team, with one minibus held up at gunpoint, and several crew members robbed of personal belongings.
Pirelli and McLaren consequently abandoned their planned post-race two-day tyre test.
The FIA requested that a report was compiled and its findings were discussed during a meeting of the World Motor Sport Council on Wednesday.
"The World Council was presented with the report on the security incidents that occurred at this year's Brazilian Grand Prix," read a statement.
"Following the report, the CRH [Commercial Rights Holder] recommended that the promoter, who is responsible for the security of the event, retains an independent security expert to evaluate and advise on security plans."
It also advised that it should "implement a police reporting hub at the circuit and improves overall communication between the promoter security, police and F1 stakeholders.
"The World Council strongly urged the promoter to implement these recommendations and improve the situation ahead of next year's event.
"The FIA will offer to participate in discussions with the local authorities and closely monitor the situation."
Brazil's place on the 2018 calendar was ratified during the WMSC's meeting, with no mention made of any consequences for the event if its proposal is not acted upon.
