Re: Restrict certain database access using 3rd party tools.

Just deny login if your trigger does not know the program.

Check the archives for example scripts for login triggers.

RE: Restrict certain database access using 3rd party tools.

2002-10-08 Thread Mercadante, Thomas F

Yechiel,

this is a never-ending chase.  security by attempting to control what
program is to be used is useless.  it will always be broken - or the DBA
will always be stuck monitoring what is being used.


security based on Oracle Roles is the only good answer.

RE: Restrict certain database access using 3rd party tools.

2002-10-03 Thread Jamadagni, Rajendra
Title: RE: Restrict certain database access using 3rd party tools.





From the TOAD help file ...


Although TOAD is intended as a developer's tool, TOAD can be made read-only via the two license files that come with TOAD, READONLY.LIC and FULLTOAD.LIC.

TOAD.EXE only reads TOAD.LIC to determine if it is full TOAD or read-only. The license file contains a setting for read-only database access. The network administrator can copy READONLY.LIC over the TOAD.LIC on an individual workstation to make TOAD read-only at that workstation.

Remember, the TOAD.LIC file must be in the TOAD folder.

RE: Restrict certain database access using 3rd party tools.

2002-10-03 Thread Mercadante, Thomas F

Rick,

Can you change the forms application?
If so, then a really simple way of doing this is to grant insert, update and
delete access to the tables to an Oracle role.

When the form starts, enable that role to grant access to the tables.  By
default, the role would not be enabled for the user.

You could even extend this idea by having a password required on the role,
and getting that password inside the form.  that way, a sqlplus user could
not enable the role.

the other ideas restricting access by program name do not work because you
do not have control of the PC desktop.

Another thing I've seen done is to establish shadow accounts.  this idea
involves a person having an OPS account with read-only access to the db
tables.  the user also has another oracle account that has total access to
all tables.  but the user doesn't even know this account exists.  again, the
forms application is run, connecting via the OPS account.  the first thing
the form does is to query a lookup table, finding the OPS account and the
shadow account/password, and re-connects to the database using this account.

this is the best idea I have found for protecting the database.

hope these help.

  --- [EMAIL PROTECTED] a écrit :  Hi All,
  
  We have users that have OPS$ accounts that have
 full
  DML privs when they
  run forms application via citrix. Currently they
 do
  not have sqlplus,etc.  There is a requirement that
  some can have
  sqlplus,toad,etc.  I know you can set up security
  for sqlplus,etc
  using product_user_profile but is there a way to
  allow only SELECT when
  using a 3rd party tool such as TOAD.
  
  Thanks
  Rick

RE: Restrict certain database access using 3rd party tools.

2002-10-03 Thread Jacques Kilchoer
Title: RE: Restrict certain database access using 3rd party tools.





Stupid DBA trick #32, or how to drive your DBA colleague wild on April Fool's day:
go over to her machine, and change the name of the SQL*Plus executable (%ORACLE_HOME%\bin\sqlplusw.exe, plus80w.exe or whatever it is) by surrounding it with parentheses, e.g. (sqlplusw).exe and change the shortcuts to point to that program. SQL*Net will NOT be happy.

 Except for the fact that they could always change the program 
 name that they
 are running to match what you need. Then that security is bypassed.

Title: RE: Restrict certain database access using 3rd party tools.





P.S. IIRC this will happen with any client program using SQL*Net:
e.g. change My_program.exe to (My_program).exe and SQL*Net will be unable to establish a connection.
