It is one of the important issues in today's world coz everything has become related to technology and everything has become online to reduce the work pressure load on the user. So regarding this matter the important issue that requires knowledge to every layman is the Client server security. There are usually three main components for the Client/Server computing which are as follows. The Client and then the Server which may be one or many depends on the user and then the Network which keeps the Client and the Server bonded together for any dealings.

The Client is the user who sends information through the computer which is simply by giving input on the screen. The server is the place where the information has to reach for the full processing of the input that has been given by the user and proper validation there are a few checkpoints. This is all present in the network which connects the user and the server, it connects in such a way that the user is able to send the information to the right server and then the server is able to process the raw data and give its result in the form of output. But the major problem during this transferring of data from the user to the server or the server to the user is the privacy invasion by some of the hackers or it can be many viruses or anything which disturbs the normal flow of data causing a hindrance on the pathway. So as to rectify these problems a Client server Security is necessary.

A Client server security keeps a check on the flow of information and it also helps in the smooth functioning of the computers. The Client server Security works on the basis of authority, first it has to have the authority to identify and then identify the hindrance in the security pathway and then it should have the Discretionary control to set things back to their normal place and then another check is done which can called as an audit and then the object can be re-used or the data can be send all over again. The major disadvantage is that there is no single security system which can handle all the problems related to the Client server security, so there are many which has to be installed and checkpoints have to be maintained at every point.
