Physical security

Your first line of defence against intruders is the furthest external part of your premises.

This might be the fence or wall and gates, or simply the facade of your building. Therefore, a good way of ensuring you have good security is to physically approach your business from the boundary and work your way to the inside, including staff and internet use. Have a look at each stage in turn and see if there are any weaknesses which may lead you to be vulnerable from offenders.
