Today the web technology is growing rapidly and so with it the threat of intruder hacking the system. Companies today depend hugely on web technology for sharing important information inside the companies. One such information system is employee information .for example Information like his personnel contacts, his qualification, his performance details etc. so net becomes a very unsafe place to host such information on system. So it’s our responsibility to think one step ahead. All computers has a Unique Mac-address .So if we can trace what is Mac address of the client system then we can make sure it system trying to access the site is valid or not. For example suppose if an unauthorized person gets valid login and password of such site even then he can’t access the system unless he login from authorized machine. This is nothing but to make sure that both the machine and the login user both are authorized. So I am planning to develop a web application which has all contains all Human Recourse related information of all the employees in an organization and implement Mac-address base authentication in this site
