What is port communication?

Is Port map Safe?
For these reasons, it is difficult to secure. Securing portmap only affects NFSv2 and NFSv3 implementations, since NFSv4 no longer requires it. If you plan to implement a NFSv2 or NFSv3 server, then portmap is required, and the following section applies.
