Risk assessment
Start with the operating environment
Good security planning begins with people, routines, access points, valuable assets and the consequences of disruption. A useful review focuses on realistic exposure rather than fear.
Build controls in layers
Physical presence, access procedures, CCTV, alarms and communication each solve different parts of the problem. Their value comes from clear responsibilities and a proportionate design.
Review after change
Construction, new operating hours, staff growth, events and new equipment can change the risk profile. Periodic review keeps the plan aligned with the site.
