Last week the Home Secretary confirmed the threat of a terrorist attack was now severe meaning one is highly likely.
Theresa May said events in Syria and Iraq was a huge cause for concern.
She's worried Islamic State (I.S.) fighters may come back to the UK to commit attacks.
Police Scotland is the first UK force to issue a direct appeal to churches and other places of worship about their security measures.
Officers have asked faith-based communities to review security at community centres, places of worship and places of education.
Assistant chief constable Ruaraidh Nicolson said: "They may wish to consider within this review what extra security measures may be proportionate or necessary. Local Community Police officers will be delighted to assist with advice and guidance if necessary.
"Police Scotland has responsibility for keeping people safe across all communities and our response to the threat from terrorism is constantly assessed and reviewed, with policing operations shaped appropriately and based on the latest intelligence analysis.
"At this time there is no specific threat to Scotland or Scottish communities, however I would ask our businesses and communities to take cognizance of this increase in the UK threat level and remain vigilant.
"Faith based communities should take this opportunity to review their security stance at community centres, places of worship and places of education.
"Whilst any increase in threat levels is concerning, Scotland's communities should be aware that we have a variety of well-established security arrangements and operational tactics in place to ensure that we remain well prepared and protected from the threat of terrorism.
"These plans have now been activated, and increased high visibility police patrols will already be evident in and around town centres, shopping centres and places of worship.
"Our officers have been encouraged to proactively engage with and support businesses and community groups in their areas.
"Police Scotland has a strong relationship with all our communities and your continued support in promoting these positive links is greatly appreciated."
