The security infrastructure is a mutually
supporting system of organisational, physical and electronic security
arrangements, which should be risk-driven, proactive, cost-effective,
practical, flexible and sustainable. It is aimed at deterring potential
wrongdoers, detecting undesired and threatening situations in an early
stage, delaying wrongdoers in achieving their ill-intended acts and
organising a response to remove the threat and normalise the situation.
