Business Security Information

While trying to catch up on some of my reading this week, I came across an article from the December 14, 2009 edition of Forbes magazine which discussed computer-controlled vending.  A vending machine is equipped with an add-on box which captures all the transactions and transmits the information back to the company.  The boxes can also send an e-mail or text message when a vending machine sells out of an item.  This type of electronic device saves the vending company money in lower fuel costs and more efficient use of their manpower.  If you are interested in learning more, you can check out the website for Cantaloupe Systems .

I have written numerous articles covering the different elements and aspects of security, but one issue I have never touched on is the importance of having quality information to make good security decisions for your business.  Quality or complete information is key to any business decision including security issues, but most businesses fail to track security incidents or issues at their company.  I have worked with a lot of small and medium-sized businesses over the years, and I have not run into one yet who does.

It seems like there are numerous websites on the Internet covering the main aspects of computer security but very few on physical security for a typical business.  On this website I try to cover all types of security on this website, but today I want to focus on physical security.

Physical security is mainly related to the protection of people, buildings, equipment and other physical or tangible assets.  Physical security is often overlooked in this high-tech business world where protecting digital assets of a business is emphasized. Adequately protecting digital assets, though, depends on implementing physical security as well.

A strike plate is a part of a door lock.  It is the metal plate that is attached, usually with screws, to the door jamb (door frame) and has one or more holes that hold the lock bolt when the lock is engaged.  When the door is closed, the lock bolt extends into the hole which then keeps the door closed.  Refer to the picture for a look at a high security strike plate.

This past month I have been working with a business regarding some physical security improvements, and one of those items was a security or intrusion alarm system.  It got me thinking about businesses that I deal with who usually ask me about why a certain element of security they have implemented, such as security systems, is not working.  Most of the time when I look at their particular situation, one or more elements of the security system does not fit their needs.  Usually this is not discovered until the system has been installed and paid for, leaving the business with a system that does not fulfill their needs and sometimes results in the system not being used after a period of time.  This results in wasted time and money for the business owner as well as poor or nonexistent security.

I just got done watching this short video (2 minutes) on installing a security door plate on a residential door with a wood frame.  It showed how this security plate could provide another layer of security against a criminal that tries to break in by kicking down your door.  As you watch, you will see that the door leads to what appears to be the speaker’s home office.  Although many commercial structures have metal doors with metal door frames which do not need security door plates, I have seen numerous offices and other commercial buildings which have exactly the same type of doors with wood frames where security door plates would have helped reduce the risk of someone kicking down the door.  Also, note that the security door plate helps the deadbolt lock resist such an attack (the door entry lock or door handle lock really is not affected by this security measure.)  Along this line, I would recommend that you install deadbolt locks on your exterior doors if you have not already.  Make sure any exterior door locks you use are resistant to lock bumping (read the definition and watch the videos on lock bumping to understand the dangers from this type of attack).

Lock Bumping, or “bumping” as it is sometimes called, has been around for the past fifty years and is a form of lock picking where a specially cut key is used to move the pins in the lock so the lock can be opened.  The key is made by cutting all cuts in the key to their maximum depth and is sometimes called a 999 key because the cuts are made to the maximum depth of 9.  The cuts can be made by using a hand file, but using a key-cutting machine speeds up the process of making a bump key.

In the picture, you can see that this business first installed metal bars to protect against someone from breaking in through the window.  As you can tell from the cut and bent bars, that was not enough security so the business went to the next level which was to remove the window and then fill the opening in with bricks.  For most businesses that are trying to protect themselves from a break-in, this  would be just too ugly of a solution.

IP Cameras are surveillance or CCTV cameras that use IP (Internet Protocol) to transmit a video image and any control signals for the camera over an Ethernet network.  IP cameras are also referred to as network cameras.  They are usually recorded using a digital video recorder (DVR) or a network video recorder (NVR).  The use of IP cameras allow the video to be stored and retrieved from anywhere on the existing network.  IP cameras also allow a business to view the cameras through an internet connection or across private networks such as LANS (local area networks) or WANS (wide area networks).  Also, IP cameras are able to be deployed or used across a wireless network.  Resolution of IP cameras, just like digital cameras, has improved over time.

A variety of different swing arm gates, similar to the ones in the pictures, are used to secure the entry points to lots and storage yards at a variety of businesses.  I have seen them at businesses such as lumber yards, a variety of dealerships, storage yards used by contractors, entrances to fairgrounds, and other similar types of businesses.  In the majority of cases, I have seen one or more things done that make this type of security barrier less effective.  To maximize their effectiveness, businesses should consider the following:
