The attack, in which six police officers and two civilians were killed and six Sri Lanka players injured, meant Pakistan became a virtual no-go area for touring teams. Apart from a brief visit by Zimbabwe in 2015, Pakistan has since been playing its home matches in the United Arab Emirates.
But last month Pakistan hosted three Twenty20 internationals against a World XI in the Gaddafi Stadium in Lahore.
The SLC said over the past two months it had conducted a thorough evaluation with the assistance of the governments of Sri Lanka and Pakistan, the Pakistan Cricket Board and independent Security experts.
"Having been fully satisfied with the stringent security measures in place, the SLC ExCo unanimously decided to play the 3rd T20 in Lahore on the 29th October," the SLC said in the statement.
The first two matches in the Twenty20 series will played in the United Arab Emirates.
