What Are The Three Basic Lines Of Physical Security?

Physical security refers to the actions you make to protect your assets, buildings, and property from threats and intruders. As the first line of defense, you have the responsibility of securing visitor management. For instance, you can collect visitor IDs and run background checks on every person who comes in.

But if you want to go the extra level, you should design an effective physical security system. Your security program must touch on the three basic lines of physical security—outer perimeter, inner perimeter, and the building interior.

What should you do to protect those three lines? Keep on reading to find out.

1. Securing the Outer Perimeter

Your facility’s outer perimeter is defined by the actual lines of the property. For security, you must be able to monitor and control who can walk and drive to your property grounds.

These measures can include installing a locked gate protected by guards, planting a simple hedge around the property, or adding a barbed-wire fence. The extent of the perimeter security you install must depend on the risk of an intruder gaining or attempting access to your property.

2. Securing the Inner Perimeter

Inner perimeter refers to the doors, walls, and windows of your facilities. In securing them, you can use alarm security systems that can warn you of an entrance breach. You can also make use of locks, access controls, keys, key controls, and electronic visitor management systems.

3. Securing the Building’s Interiors

For interior security, you have to invest in protecting employee offices and all of the confidential information they hold. In monitoring the interior spaces, it is important to invest in motion detecting security cameras, access control systems, and alarm systems.

For the best security you can provide for your business, it’s essential to invest in measures that would protect each of the three levels. With risk management, the best move is staying proactive.
