Re: Commands for Limited Users

Jim,

Sorry, I should have been more clear.  This is the list of commands that
limited capabilities are allowed to run from an OS/400 command line.
But as I mentioned earlier, there are other interfaces that limited
capability users can use to run these (and other) commands.

LMTCPB users can are not restricted from running other commands from
within a compiled program - assuming they have at least *USE authority
to the command object.

John - is this list commands they can execute from a
command line, or the
total list of commands they can execute, even if the
command is within
a clp program (assuming normal auth to the pgm, not
adopted, and the program
executing under the authority of the user of the program,
not the owner)?
It was my understanding that this list was a limitation of
what a limited
user
can do on a command line.

Dave,

I'm reciting this from memory, so it may not be an

exhaustive list, but

if I recall correctly there were somewhere around 8

commands shipped

with the operating system that are available to limited

users.  Let's

see which ones I can remember, and then we'll see if

others can chime in

with any I may have missed.

DSPJOB
DSPJOBLOG
DSPMSG
SIGNOFF
SNDMSG
STRPCO
WRKENVVAR
WRKMSG

Of these, SIGNOFF is virtually essential, and the three

"DSP" and the

SNDMSG command are relatively inconsequential risk

(assuming you are

doing appropriate tightening elsewhere, as you have

said).  STRPCO is

risky, and probably completely unnecessary, and, absent

a specific

reason to leave them open, the WRKENVVAR and WRKMSG

could afford to be

restricted as well.

This list only includes commands that are allowed by

Limited Capability

users as shipped from the factory.  You may have more OS

commands or

application commands that have been opened to Limited

Capability users

as well.  There is at least one commercial product (uh,

why yes, that

would be a PowerTech product :) ) that will show you

this list quickly

in a single report (and help you ensure that the list

stays constant),

but I am not aware of any automated facility in the OS

that will track

this parameter for you.

HTH,

jte

Subject: [Security400] Commands for Limited Users

I am trying to get a handle on security on our systems,
and have now
arrived at "Commands for Limited Users." I have an

Excel

spreadsheet
which has all the commands in this category on our
systems.

First, I would like to know what are the commands for
limited users that
come with the system as shipped from IBM. Second, do

you

agree with that
list? I.e., should there be ANY commands available to
limited users?

I await your reply.

Thank you,

Dave
