Security management is essential to any company. There are many different aspects of security management including Computer Network security, Entry Identification and Logging system and Fire Detection and Prevention.

Companies are increasingly using programmed magnetic or chipped Identity Cards for employees that allow access only to specific parts of the site. The system records every entry and exit made, meaning that access to sensitive areas is automatically limited and the person responsible for any theft or damage is easily identified. Theft and damage are reduced of course, because employees are aware of the system, its capabilities and the increased likelihood of being caught.

Heat and smoke detectors are generally wired to a central control room that has instant video access to any area where an alarm is raised, meaning that false alarms are quickly identified and productivity losses are minimized.

The technology has fallen in price so much that even schools and colleges have chipped identity cards for staff. The system is more acceptable to clerical and professional staff than clocking in and out, but achieves that function as well as its primary security function.

Video surveillance is a part of modern life. It is used in all shops and many production facilities. The output from all the cameras can be output to a single screen as large thumbnail pictures, where security personnel can zoom in on any suspicious activity.

Computer Network Security has a very high profile in most companies. If someone from outside managed to get into the network they could either, create mayhem by deleting essential files, or they could steal confidential company data. Firewalls are designed to prevent this happening. Computer Network Security is much more than checking for hackers, though. More damage is caused by employees' unauthorized use of files from home PCs which have viruses on them. Network PCs in many companies no longer have floppy disk drives, or even CD drives to prevent employee damage to the system in this way.
