Smart cards have provided an innovative means for storage and portability of data in business and computing systems. The smart cards are accesses far and wide and for many-many applications. Thus they have their own security management issues.
Data security covers a wide range of applications that we come across in our daily lives. As the technology is advancing at a great pace and has started governing almost every sphere of our daily lives, data security is a very important issue. The networks of the computing systems are highly interactive, located far and wide and are inter-dependent. At all places data is being created and shared among those at the network. It is updated, and stored at different locations. The data and users both show a great diversity. All these diversifications and interdependency gives rise to an imperative need of security systems. These security systems are needed to protect the secret data, and also the whole lot of data against unethical use. It is also crucial to protect the rights and work of the users of the network.
There are many methods adopted to manage the storage and sharing of data, ensuring its privacy and safety. The application of these means is the Information security. Technical implications of this information security, deal with technical method, cost and extent of applications. The social implications of the information system concern the public, individual freedom, privacy, ethics and laws. The final choice is of the system designed and the employer of the system.
The system has the normal computing system elements like hardware, software, data and the personnel. The servers, mass storage devices, remote devices, communication lines and channels, the smart cards, etc are the hardware. The operation system employed in the system, the DBMS, the security programs, and the communication application constitute the software. The entire customer related information and related databases are the data for the IS. The final link, the humans i.e. users, professionals, computer professionals, clerical and administrative staff working on the system are the personnel.
