The decision to increase surveillance and introduce tougher regulations for players and officials of the six franchises were taken in a bid to avoid the spot-fixing scandal that hit the second edition of PSL last year.
The scandal led to five-year bans of Pakistan batsmen Sharjeel Khan and Khalid Latif and also temporary suspensions of other national team players Muhammad Irfan, Shahzaib Hasan, Muhammad Nawaz and Nasir Jamshed.
The PCB has already placed advertisements for the appointment of integrity officers for two months to beef up security and vigilance of teams during the PSL.
The source said the PCB had also changed the hotel where the franchises and officials used to stay in the first two editions of the PSL.

The source said that the PCB is keen to restore a clean image of the PSL which has become a successful brand now.
