NIC is providing dialup Internet facility to users from more than 20 locations. Till now, different locations were using different means for authentication like tacacs, local, tacacs+ , third party software etc. There was no AAA (Authentication, Authorisation and Accounting) standard being followed from the various offices. The Internet Services Group of NIC has taken the task of implementing the AAA standard in all offices of NIC. Radius (Remote Authentication Dial In User Service) is the protocol used for implementing the AAA solution. The code runs on Solaris/ Linux. Radius Technology has been selected for the purpose as it is now the industry standard. It uses UDP and can assign various restrictions and privileges to users dynamically. Radius supports Roaming facility and users can be restricted on group, login basis etc. Radius support is available on almost all NAS devices. In the first phase of the Project, the radius software was installed and configured with the local NAS. While installing, five standard groups were also made in the system namely: free, paid, staff, popfree and poppaid. Basically FREE and PAID groups are for internet users and POPFREE and POPPAID group are for ‘email-only’ users. The Staff group is for NIC staff. While creating the users it was requested that a dialup user should be one of these five groups for dialup access. Thus this enables a uniform grouping policy for dialup. Each group has its own authorization features for e.g the users in the Free and Paid group can access all internet services while the users in the POPFREE and POPPAID groups, can access inside the NIC. Accounting scripts were also installed during this phase and a half day training was organised. A web based password change facility was also implemented for the users of these locations. Now users can change their password through the web URL www.ren.nic.in In the second phase roaming facility was implemented. Now the dialup users of 20 cities listed in the table can be authenticated from all the listed places for accesing the network. Hence there is no need for creating the multiple user-ids at different locations for the same user and the users can roam among these 20 locations. Example: Suppose “xyz” is the username created at Delhi and the user wants to use the dialup from Mumbai. The user has to dial the local number of Mumbai NIC office as listed in the table given below and give the username as xyz@pppdel Rest of the procedure remains the same. The RADIUS will authenticate the user from Delhi. In the next phase technologies such as ISDN line authentication, use of calling telephone number with username and password to provide further credibility to authentication mechanism, web based radwho, usage display from same web location etc may be also be implemented.
