SECURITY of CLOUD STORAGE: NAC, TLE and VPD APPROACHES

Abstract

This is the age of Information Technology (IT). The cloud computing are the biggest concept in this era and another core concept than cloud computing is that security of cloud storage. Without security of a system is like as a boat without rudder. In this time there are lot of system and method which make our life easy but security of that system is the major question. In this time the lack of security is vast problem in our life. Many resources and data are hacked day by day. So, security is the most important matter in our technology. The Network admission control (NAC) protocol is an end point device technology and solution which is provided by Cisco. It is also called Cisco NAC. NAC identifies all build up a strong security self-depending network and gives an extra performance. This paper describes how to NAC allows trusted endpoint devices and deny the access of unauthorized devices in a network or network zone. The Two Layer Encryption (TLE) techniques are that provides the extended secure communication. And the virtual Private Database (VPD) is a concept of oracle that allows the DBA (Database Administrator) to control access to data in the database. It is secured all user information row and column level so that nobody cannot see the user’s data Except DBA (Database Administrator) in this system.
