Students from several tertiary institutions in Singapore, including SUSS, have gotten together to organise a concert to promote racial and religious harmony in Singapore, and around the world. This concert will be held at the Fort Canning Green with the permission of NParks. It is located behind the National Museum of Singapore, near to the Singapore Management University. About 1,000 participants and members of the public are expected to be there. It will be managed by student volunteers. Current plans of the organising committee call for a large stage to be put up at the bottom of the Fort Canning Green, where the audience can lay out picnic mats and sit on the lawn that stretched from the Fort Canning Arts Centre down to the stage. There are two walls on either side of the lawn but otherwise the venue is open for members of the public to walk in from the various footpaths surrounding it.

Tickets would be sold online for a nominal sum of $2. The committee has decided to make use of Eventix, an online ticketing company, to sell the tickets through its online sales page and collect the money through online payment. To purchase a ticket, a buyer will have to enter his particulars, including his full name, his phone number and/or email address.

A local event management company has kindly agreed to sponsor the sound and light systems for the concert but has requested for someone to guard the equipment from when these were brought to the venue, during the concert and until after the concert when their movers would pick them up. As part of this concert, not only are acts and bands from local tertiary institutions invited to perform, but those from other countries as well. As some of them are from countries involved in recent conflicts, the Singapore Police Force has some concerns about the security surrounding the concert venue and asked for more details on security arrangements before they are willing to issue a permit to hold the event. Your friend is on the organising committee of the concert. He knows that you have recently taken a course on security risk management. To help the committee with its application for a permit to hold the event, he has asked that a security risk assessment proposal be proposed, about the suitability of the venue selected.

Based on the context above,

What are some strategies that can be formulated to discover the various risks faced by the concert, particularly the risk assessment approach, the data to be collected, the sampling plan, the analyses to be conducted, and the measurement standards/framework to be used as benchmarks (if any)? Why are these methods/strategies chosen?
