Security management refers to a large area in the management of physical and material assets. This management process entails conducting research to find out the types of inherent and potential risks in an organization with the aim of developing policies to effectively eradicate or mitigate those risks. Security management is used mostly in conjunction with information technology and its application toward preventing the breach of computer security that can result in the loss of sensitive information or the breach of computer-controlled security systems. Poor security management can lead to the loss of human lives. An example of how this may occur is if a breach in a computer-controlled alarm allows intruders to enter premises and harm the occupants.
When setting up a security management system, an area of concentration and consideration includes installing measures to prevent the physical theft of the assets of an individual or an organization. For instance, effective security management in a big retail department store will allow for the monitoring of customers with the aim of preventing incidents like shoplifting, purse snatching, and even child abduction. An effectively managed network of cameras and computers will be integrated in such a way to monitor the different corners of the store, including the parking lots and other hidden corner.
The same concept applies to organizations like museums where highly valuable items are stored. Security management involves the integration of technology like sensors, cameras and laser beams in conjunction with a highly functional computer backbone to prevent theft. Another aspect of security management is its use in the limitation of access to sensitive data. In large organizations, access to some information in the computer network may be limited to only a few members. Such limitations may be enforced through the assignment of access codes, which will permit only those with certain authority to access the information.
This may also apply to restricted portions of a building within an organization. Through security management, such portions will only be accessible to those who have been granted access. The access may be in the form of finger scans, retina scans, voice-activated codes, numerical codes or a combination of numerical and alphabetical codes. After the security system has been set up, constant upgrades and maintenance will ensure that the system stays updated and more efficient at managing security. Examples of this include updating software and also old hardware to newer, more modern versions.
