CHAPTER ONE

INTRODUCTION

Computer Security Guard (CSG) is an important aspect of any system.  Computer Security Guard is the act of ensuring that an authenticated user accesses only what they are authorized to and no more.  The bad news is that security is rarely at the top of people’s lists, although mention terms such as data confidentiality, sensitivity, and ownership and they quickly become interested.  The good news is that there is a wide range of techniques that you can apply to help secure access to your system.  The bad news is that as Mitnick and Simon (2002) point out “…the human factor is the weakest link.  Security is too often merely an illusion, an illusion sometimes made even worse when gullibility, naivette, or ignorance come into play.”  The go on to say that “security is not a technology problem – it’s a people and management problem.”  Having said that, my experience is that the “technology factor” and the “people factor” go hand in hand; you need to address both issues to succeed. 

            Access control is the ability to permit or deny the use of a particular resource by a particular entity. Access control mechanisms can be used in managing physical resources (such as a movie theater, to which only ticket holders should be admitted), logical resources (a bank account, with a limited number of people authorized to make a withdrawal), or digital resources (for example, a private text document on a computer, which only certain users should be able to read).

Banks are secured financial institutions. They are often housed in large buildings that are located in a commercial or residential area. Banks store money and other financial information and goods.

Money and valuables have been stored in banks since ancient times. As a result of the long history that banks have enjoyed, bank security has also been important for a long time. Some of the oldest banks in the world have the best security available. These banks include the Bank of Sweden, the Bank or England, Bank of America, and Swiss Banking.

Bank security usually includes a staff of security guards, a security system, and one or more vaults. Security guards are uniformed personnel that maintain high visibility and watch cameras and alarms. Cameras and alarms are usually top of the line systems in banks and other financial buildings. But these security elements are not exclusive to banks. Some of these elements can be found in other commercial buildings and even residential homes.

Basic security starts with the locks. For a high level of security, windows and doors will need the best locks. After high quality locks are installed many property owners opt for a security system or even security cameras.

Security cameras are often a small part of a larger security system. Systems often include motion detectors, alarms, sensors, and cameras. Cameras are arguably the most important because they allow the property owner to see and record everything that happens in and around their building or property.

Cameras can be installed by a professional or by a property owner. For a large and elaborate system it may be best for a professional to do the work. But for a smaller and easy layout, a property owner should have no problem installing a system by following the manufactures instructions. If he does than there is usually a local installer that can be called to help finish the job.
