At its broadest sense, security refers to all the measures one takes to protect a place, an asset, an interest, or a group of people. In business, however, security could refer to a lot of things. It could mean financial security, computer security, information security, legal security, or physical security. It could also refer to the precautions firms take to safeguard trade secrets or keep the lid on a sensitive project. There are many security systems and measures that one can adopt in the workplace. Surveillance cameras, for one, could be put up in strategically chosen places to monitor the goings-on of any cubicle, any department, or any floor any time of the day.
