| Summary/Abstract |
In the present cyber age, public services are getting more and more dependent on use of Information and communication technologies (ICT) day by day. A number of applications viz., Internet of Things, PDF, cloud computing and virtualization and machine to machine (M2M) system usage are sneaking deeply into our everyday life. The more we depend on ICT, the more deepens our concern about IT security or cyber security. Cyber security protects the data and integrity of assets that belong to or connect to a network. It is meant to defend those assets against all sorts of threat actors throughout the life cycle of a cyber attack. It is quite unsurprising that cyber security industry is growing at the same pace as ICT is doing.
