Post an idea.
Get feedback from the IBM team and other customers to refine your idea.
Follow the idea through the IBM Ideas process.

I would like to request a security enhancement to the TS4500 CLI tool to support authentication credentials to be read from a file on disk of the workstation.
Today, typical TS4500 CLI usage is something like this:
# java -jar /opt/TS4500/TS4500CLI.jar -ip <TS4500-IP> -u <our-username-here> -p <our-pw-is-here> --viewDriveSummary
The problem with how the tool works is that it will run sometimes for tens of seconds or even minutes, depending on the task. While the CLI tool is running, any unprivileged (non-root) user can run 'PS' and see the password in clear text. Here's an example:
[operator@swift ~]$ ps faux | grep TS4500
root 3302 1.7 0.0 35760408 70372 pts/3 Sl+ 10:50 0:00 | \_ java -jar /opt/TS4500/TS4500CLI.jar -ip 192.168.128.73 -u admin -p <our-pw-is-here-in-cleartext> --downloadResources MountHistory

IBM has reevaluated the request and has determined that it cannot be implemented at this time or does not align with the current multi-year strategy.
You may continue to view, comment upon, upvote, and subscribe to ideas marked as not under consideration. IBM will review and may reconsider ideas if new information surfaces or there is additional client interest in an Idea.
IBM has re-assesed this request and has determined to implement this security enhancement on a future release.
From what I see in the CLI encryption topic referenced, this is just specific to encrypting/scrambling a clear-text password via
--encrypt <Encrypt a Password>
.However, anyone on the machine can still run
ps
and see the encrypted password while a CLI task or command is running. While it does not reveal the original password used, anyone who captures the encrypted password will still have full administrative access to the TS4500.For example:
$ java -jar /opt/TS4500/TS4500CLI.jar -ip 192.168.128.73 -u admin -p <our-pw-is-here-in-cleartext> --encrypt "blah"
yRgW
$ ps faux | grep TS4500
root 48278 62.0 0.0 35760036 74012 pts/0 Sl+ 11:53 0:00 | \_ java -jar /opt/TS4500/TS4500CLI.jar -ip 192.168.128.73 -u admin
-ep yRgW
--downloadResources MountHistory
Please note that I can see what the encrypted "admin" password is, even as non-privileged user on this machine.
The other part of the request is to be able to specify the CLI credentials from a file on disk. So for example:
java -jar /opt/TS4500/TS4500CLI.jar -ip 192.168.128.73 -u admin -p ~/.my_ts4500_pw --downloadResources MountHistory
This is already supported, please see the following reference:
