Add a exit point option to be executed at the end of a FTP or SFTP process

With increasing demands on security, FTP has exit points when starting a FTP process but not when it ends.

We have a need to monitor all FTP processes when they have completed. This includes inbound and outbound processes.

Providing access control up front is insufficient as someone could have access to use FTP but they may transfer unauthorized files.

The user exit has many uses but the primary use would be to work through the logs and validate the transfers.


Use Case:

The user exit upfront has several uses but is primarily used to grant access to the FTP process.

Once a user has access, they can transfer any data and there is no control over this.

In addition, people use FTP to execute commands.

A method to review what was done with FTP is required and needs to be beyond the programmers control especially where a remote user performs work.

    IBM has previously requested more clarifying information. Because the additional information was not provided within 30 days, the request has been closed.

    The CAAC has reviewed this requirement and recommends that IBM not implement this request. This scenario is not an FTP problem -- it is more of an object authority challenge that can be resolved by properly locking down the objects.

    Background: The COMMON Americas Advisory Council (CAAC) members have a broad range of experience in working with small and medium-sized IBM i customers. CAAC has a key role in working with IBM i development to help assess the value and impact of individual RFEs on the broader IBM i community, and has therefore reviewed your RFE.

    For more information about CAAC, see www.common.org/caac

    For more details about CAAC's role with RFEs, see http://www.ibmsystemsmag.com/Blogs/i-Can/May-2017/COMMON-Americas-Advisory-Council-%28CAAC%29-and-RFEs/

    The FTP performs restriction to one user's action based on the user profile's authority. When a user can access one file or object, after he/she log on to the ftp server, the user have the capability to download the file/object. The user can upload the file/object when he/she can modify the file/object. The file system's authority setting limits the user's capability.
    This is also true for the FTP cmd "SYSCMD CALL cmd". The user should have *USE special authority to run the command.

    FTP controls whether one user can run ftp commands, such as run a CL on the IBM i via the ftp. one user to run CL command in ftp. The Operation-specific information of format VLRQ0100 of exit point QIBM_QTMF_SERVER_REQ contains the CL command if the ftp client run the CL using SYSCMD. This can be used to track what commands one user run via FTP client.

    FTP did not provide a log after the command completes. Using exit point QIBM_QTMF_SERVER_REQ can keep a track when the command is issued by ftp client. This provides some sort of logs .

    Does this satisfy your requirements?

    IBM has received the requirement and is evaluating it. IBM will provide a response after evaluation is complete.

    Wouldn't the QIBM_QTMF_SERVER_REQ with the VLRQ0100 exit point interface meet your needs? It isn't called at the end of the process, but it does allow you to create a log file of what is being executed through FTP. I have an exit program that creates a log file like this in addition to providing control, like stopping certain users from executing commands, and stopping anyone with special authority from sending or receiving files from a remote IP address. It provides very granular control where some users could upload files and nothing else, not allow changing directories, etc. I use a file that contains authorized FTP users and a flag for each function to determine their level of access. If the user isn't in the file, they are also blocked from using FTP.
