| dc.description.abstract | Authentication provides access to server, networking equipment, application and other services after verify user's credential from authentication server. Authentication system is important because it keeps organization secure by allowing only authenticated user to access the network resources. Administration of Data Center is another area, where maintaining secured access is very important. Today UNIX administrators use only user name and password to access server for data center administration. Traditional user name and password is vulnerable because attack can happen by password theft, snooping, brute force attack. To protect login information of administrator, we have developed a multilevel authentication system that provides strong three level protection since administrator will be prompted for password, verification code and single sign on. Once three level will be matched with authenticate server, administrator will be allowed to access server for administration in data center. In multilevel authentication system we have used password, Time based One Time Password, single sign on. | en_US |
