We just not recovered from the terrorist incident that happened at west gate. There is need to enhance security at premises, home, public transport e.t.c;

Some points to note;

1. Entry to access roads should be furthest from entry premises.
2. Multiple barriers or speed bumps to reduce speed.
3. Entry points covered on the CCTV and continually monitored. CCTV should be be accessible off site..DVRs should be IP capable with proper escalation, incase of an incident
4. Enhanced access control systems..biometrics.
5. Know your neighbour

More please
