No. Not really.
You can forbid some statements for users using PRODUCT_USER_PROFILE table.
Have a look at SQL*Plus� User's Guide and Reference, Chapter 9 SQL*Plus Security

create a logon that does a query similar to below:


SQL> select program from v$session where username = 'DBADMIN';

PROGRAM
------------------------------------------------
sqlplus@stagedb01.hitbox.com (TNS V1-V3)

when "sqlplus" is detected, just ALTER SYSTEM KILL SESSION

sqlplus does not mean sqlplus?
Is this not the subject of the topic?

Michel,
I did not claim it would be 100% effective.
IMO, the OP is chasing fools gold.

cp sqlplus fubar
./fubar dbadmin

PROGRAM
------------------------------------------------
fubar@stagedb01.hitbox.com (TNS V1-V3)

With available of freeware like squirrel such attempts by OP are nothing more than security by obscurity.

Yeah obviously there is solution. U can block SQLPlus, from taking import of database, from connecting TOAD, Even user cannot take data from Microsoft EXCEL Without ur permission.

To get it u have to write a trigger in SYS schema and include the exe files and exclude DBA users to get connect from SQL, TOAD and tools and restrict users to get login just from application Forms.

Yeah obviously there is a way to workaround your trigger: rename the executable.

No Filename renaming would never work. Bcoz when u rename the sqlplus.exe and after renaming when execute, Engine will tell to database listener that SQL want to connected, the hardcoded u cannot change. U can check it. ok

begin
FOR REC IN (SELECT USERNAME,PROGRAM,MODULE,TERMINAL,MODULE_HASH FROM V$SESSION
WHERE AUDSID = USERENV('SESSIONID'))
LOOP
if rec.username not in ('SYS','SYSTEM','ABBC','XYZ')
and
upper(rec.terminal) not like '%Computername%'
and
(rec.module is not null
OR
upper(rec.program) like '%EXP%'
OR
upper(rec.program) like '%IMP%'
OR
upper(rec.program) like '%VRMGR%'
OR
upper(rec.program) like '%EZSQL.EXE'
OR
rec.program is NULL
OR
upper(rec.program) like '%TOAD.EXE')
then
RAISE_APPLICATION_ERROR(-20001,'Sorry You are not Authorise to Logon from this tool');
end if;
end loop;
END;

Create it in SYS Schema and let me tell that from SQL/PLUS/EXP/IMP and MS EXcel u can connect r not?
