Every organization that grants remote access privilege to its users should have provisions made to include this service in its security policy. Remote access can be a very useful service, but if certain security procedures are not properly implemented the organization can be at risk. The following are points to consider when implementing remote access:
A group account for remote access should be created in the NT domain. The user names included this group should be different from the network user names. An example is that the network administrator may want to prohibit network browsing for remote users. You can effectively create and implement a security policy by setting up a group account for remote access.
Dial-up passwords should be different from the network log-on passwords.
Selecting the callback radio button and including a telephone number can ensure authenticity for that user.
Users with dial-in permission should be given only certain hours to access the network if possible. This can reduce network bandwidth.
There should be multiple access lines for users who will be using remote access service. One of the telephone lines should be made available for network-administration purposes only. This can allow the network administrator to dial in periodically and monitor audit and security logs.
You should make sure that all users who are granted dial-in permission have updated antivirus scan engines installed.
Make sure you install the latest service pack update for Windows NT/2000.
