Technology and physical protection cannot replace operational awareness.
A barrier left open at the wrong time provides little protection. A road closure implemented differently from the security plan can create a new vehicle approach. A legitimate vehicle admitted without appropriate controls can bypass an otherwise effective perimeter.
The people operating the site therefore need to understand:
- What they are responsible for;
- Who can authorise vehicle access;
- What abnormal activity looks like;
- What to do when a control fails;
- How information should be communicated;
- How emergency procedures are activated.
NPSA includes security awareness, incident-response planning, training, operational security, traffic management and physical obstructions among the measures that can form part of HVM.
Training, briefings and exercises are a critical complement to physical protection.
The bigger idea
Effective Hostile Vehicle Mitigation is not simply about installing stronger barriers.
It is about understanding how a hostile vehicle could reach a crowded place, reducing what that vehicle can achieve, and positioning appropriate protection where it matters most.
Digital tools help turn that reasoning into a security plan that can be understood, discussed and implemented in the real world.
