Configuration management is the act of controlling, determining, and updating the characteristics of any element of a computer system if trouble occurs, with emphasis on its software functions and hardware components. By using configuration management, you can distinguish the technical problems of the system, and what particular component is affected, so that appropriate problem solutions can be applied.
The good thing about configuration management is that when any alteration is made to the coding, version, and address of the computer software and hardware, it is immediately documented. The records can then be used for evaluation if any error occurs again. Moreover, configuration management acknowledges and tracks the actions taken for the system, (such as when you are downloading, and saving a downloadable program from the Internet; accessing or altering files; connecting different PC units to one computer unit which is solely responsible for Internet access of all the PCs; and installing or accessing a hardware component.). It also records the programs being executed as well as alerts the users about unauthorized access to files, and of the presence of illicit and harmful sites on the net. Likewise, it can also execute recommendations on how to use unusual functions of the computer system, and even how to resolve software inaccuracies.
Configuration management is being used and adopted by many sectors in society such as different companies engaged in telecommunications, BPO (or Business Processing Outsourcing), military organizations (for surveillance purposes, and information haulage), the government (for its inter-departmental communications and access to worldwide affairs), and – the biggest client of all companies dealing with cyber-applications.
