England's tour of Pakistan later this month is not the first time the team has travelled to the country; in October the team played seven Twenty20 internationals, their first games in the country for 17 years.
All games proceeded without incident with players surrounded by military protection.
Wood, who also played in the T20 series, stated "from the security we had then I can only mention what we came across, and it was fantastic."
However, comments made by Wood surrounding the recent attack on Khan differed in tone, with the cricket player stating the attack was "worrisome".
The former Prime Minister was injured on 28th October as he travelled to Pakistan's capital Islamabad for a rally.
Wood trusts the ECB to assess any security concerns, but the ECB is yet to make any public statement regarding the tour.
