I have questions regarding the FTP on SAS grid server:
1) Is it a safe way for data transfer between PC and SAS server?
2) is FTP allowed at your company's SAS server? I want to know the standard procedure about it.

First, I would use SFTP instead of FTP, for sure. Other options could be a shared file system. The latest versions of EG also allow to transfer files to the server from a PC.
I am not sure if there is a standard... I guess it depends on each company. I would say that the most common way to transfer files is just a secured shared file system and/or EG. A shared filesystem is a specially good choice if you are speaking of a Grid environment.

Hello @Jade_SAS, a pleasure.
This is what I meant: https://en.wikipedia.org/wiki/List_of_cryptographic_file_systems then you can create a shared folder or a mount on the top of it.
Anyway, just using your current shared or clustered file system on your Grid (a new one, to not fill in the current one whis is supposed to be for your SAS configuration only) should be enough. Then the last step for you would be to create some shared folders where only the people you want can access.
Also, as said, SFTP is another good option. SFTP is just the secured version of FTP.

Use secure shell. The standard FTP and telnet ports (21 and 23) should be closed anyway on any production server.
Both protocols work without encryption, and allow the retrieval of passwords with a simple network sniffer.
sftp is a secure shell client.
