LOGON ON TRIGGER를 이용한 접속제한 | TRACE 설정
===============================================
PURPOSE
데이터베이스에 접속하는 IP, USERNAME으로 접속을 제한하거나, TRACE를 설정하는 방법에
대하여 알아본다.
Explanation
DB를 접속하는 사용자를 USER/ROLE로 구분하여 관리하는 Accecs Policy 라면 관계 없지만
하나의 USER/PASSWORD로 Application을 이용하는 경우에는 Application을 통해서만
DB에 접속하도록 통제하는 것이 불가능하게 된다.
즉 일부 사용자가 PC에 설치된 SQL*Net을 통하여 SQL*Plus나 3rd party TOOL로 DB에 접속하여
데이터의 열람/조작을 한다면 이를 방지하거나 추적하기가 어렵다.
아래 예제는 DB server로의 TELNET접속을 통한 특정 DB User(SCOTT)의 접속을 원천적으로 막고,
특정 IP(152.69.41.232)로부터 접속하는 Session에 trace를 설정하는 예제이다.

Logon Database Trigger

I want to write a database trigger that fires when a user logs onto the database. Oracle has this in 8i+.
I am using 9i.
I want to use this trigger to determine if the session is questionable(ie. Hacker). If it is then i want to either kill the session or audit it.
Auditing is turning on for the database.
I am trying to use
execute immediate 'audit all by %username%'
where username is from the v$session for the current session.
It appears the logon trigger is fired but the session is not being audited.
My question is how can I make the session be audited from within a trigger?
Thanks for you help.

When I login in sqlplus I get the error from the after login trigger, but after I get logged in I can issue ALTER SESSION ENABLE RESUMABLE and it works fine (session altered) So why does it let me alter the session after I get logged in, but not during the after logon trigger.It's probably because you have the privilege granted to a role and not a user. Roles are disabled when it comes to definer's rights (default).

Trace in the listener.log

Hello,
Can we monitor failed connctions (ORA-01017: invalid username/password; logon denied) to trace the listener.log
Does exist an option to do that ?
Thanks for your answer
Fabrice

You've already been provided hints on using Database Audit.
However, to answer your question : The reason why listener.log cannot log such errors is that the Listener does NOT do any authentication. It does not validate username/password pairs at all. When a connection request comes in to the listener, it just verifies if the request is for a valid SID / SERVICE and redirects the request to the database instance , having forked a server process. It is the server process in the database instance that does the authentication.

Trace IP address of Successful login

Hi
We have had a security incident within our company. We know the user name (Windows Username) that was given elevated rights either by accident or on purpose. What we can't pick up is from what PC this account was used to access the database.
1) Is there a way using the transaction logs to determine the IP address of machine that was used.
2) Can we check when the windows profile was changed and by whom
3) is there any advice on how to go about tracking down the culprit through SQL server or other means after the fact?

Hi Stephen
by elevated rights/permissions you mean on SQL Server and not Windows AD already, right?
I am not aware that the IP Address is captured in the Transaction Log.
Using the default trace, located under your Log-folder, you should get the Host-Name though.
The Default Trace captured the following Security relevant events:
Security audit events
Audit Add DB user event
Audit Add login to server role event
Audit Add Member to DB role event
Audit Add Role event
Audit Add login event
Audit Backup/Restore event
Audit Change Database owner
Audit DBCC event
Audit Database Grant, Deny, Revoke
Audit Login Change Property event
Audit Login Failed
Audit Login GDR event
Audit Schema Object GDR event
Audit Schema Object Take Ownership
Audit Server Starts and Stops
So, if you still have the trace files from that date range, you should find the privilege elevation aka
escalation.
I am not sure what you mean by "Windows Profile". That would be an AD matter and logged at the DC.
For forensics several methods are being used, beginning by using the ErrorLog (by default only containing failed logons) and default trace up to a memory dump. General rule would be to freeze all activity on the machine under examination. This depends on
the level of the security incident. YMMV

Batchs taking time

Hi,
we are using production database 9.2.0.6.0 .
lot of batches are running in this databases daily . batches are (function,procedures etc.)
from last few days these batches are taking more time then previous time. There are no changes in structure of database .I checked for blocking sessions also during batch run but no blocking sessions are there .
where i can check for finding the cause ....
any idea...

Sorry if my original post wasn't clearer.
Tracing a session like execute dbms_system.set_sql_trace_in_session(sid,serial#,true) will trace a currently logged in session as of the current point.
In the past I have setup a database logon trigger and traced all the sessions. Problems with doing this a user has to have the 'ALTER SESSION' privilege to enable tracing, if sessions connect through a connection pool then these need to be restarted/recycled (not possible sometimes) to capture the login and the tracing may generate alot of trace files (filesystem issues). Also, I've come across some bugs with logon tracing (creating trace file names with sys_context('USERENV','SESSION_USER') in the filename has caused problems on UNIX with OPS$ users, does not like $ in the filename and will error, possibly locking users out).
The other approach you can take is enable tracing in the PL/SQL code or the beginning of the batch job.
Another approach altogether is forget about tracing and take statspack snapshot before and after the job.

How to create one user for one workspace

Hi experts,
I just wanted to know if anyone of you ever generated a user in a 11g database who only is able to see the content of one specifc workspace.
The workflow would be that an admin-like user generates a new workspace and after this he creates a new user who can only see/change the data in this workspace.
So when the new user is logging in, he is automatically in this new workspace and he has no priviliges to merge/create/rollback workspaces, or to change into another workspace.
Could anybody please give me a hint on how to achieve this?
Regards,
Jens

Hi Jens,
Along with granting privileges on the specific tables, you would need to grant ACCESS_WORKSPACE using dbms_wm.grantWorkspacePriv on the specified workspace. Without granting any other privileges, the user would not be able to create additional child workspaces, or merge/rollback the workspace. Then, you would need to create a logon database trigger that places the user in the appropriate default workspace.
However, a user is always able to access the LIVE workspace. There currently isn't any way to prevent that.
Regards,
Ben

Wants delete user based on their last login details...

Hi All,
I have one question regarding oracle database user management. I have approx 300 users in my each Database and I know many of them are not actively used. I want to generate users report based on their last login information. I want to fetch list of users who is not logged in database since last 4 months and are eligible for delete operation. Please guide me how to find this details.
Thanks in advance...

user12115, but really even if the logon time was not present and you only had the logoff time you know when the customer last used the system and relistically you could work with that. Rather than audit user session connection due to the large number of connections/disconnects we have per day we created a database logon event trigger that updates an IOT for the username, logon_date of the OS user connecting. If no row is updated we insert the username.
Also keep in mind that many web based applications connect to the Oracle rdbms using an application username as not as the real end user. In such a case auditing will not catch the real end user nor will the logon trigger unless the application uses dbms_application_info to post the real end username to Oracle. If this is not true in your shop today it might be tomorrow so keep this potential issue in mind.

Peak Load

I am looking for a way to repopulate some simple state information (list of
proxies) to a backup copy of one of my SO's once the primary SO fails over.
I had sent a request to the news group awhile back and received some great
suggestions about writing to a file or to the DB. However, since the state
information is data that CAN be recovered by the client app (i.e. node name,
client id, pointer or proxy through the passing of an anchored object) we
decided not to write this data to persistent storage but rather have the
client re-register themselves with the SO by sending the appropriate info
over to the SO (including the proxy back to the client). My question is
this: If the SO goes down while a large number of users are logged on (lets
say 500) and they all re-register themselves on the backup SO at the same
time (passing 3 TextData objects and a proxy to the client) how much load
will this cause and will it be enough of a load to hang the application?
Another Question is: How does one go about forcing an SO to failover for
testing purposes?
Thanks you for your assistance!!

You can also use audit features of the database to audit user connections/disconnections and write the query to get what you need.
Or you can also use with 9i/10g a LOGON/LOGOFF trigger to audit session connection and disconnection in a audit table and then write the query on this audit table to analyze the maximum number of connections.
Got from somewhere in the forum.

What other V$ view than V$SESSION can provide the "program" column ?

Hi all,
We get a blank value , no value then, given by the "program" column of the V£SESSION view when our after logon database trigger fires. This is perhaps because we use a forms R6i application which uses a 8.0.6 version of oracle client.
So I want to know which other V$ view can be joined with the V$SESSION view to get the program column.
Thank you very much indeed

Modifying the sqlnet.ora has 0 to do with the issue at hand.
Face it:
if the client executable doesn't have provisions to expose the program name,
you will never see it in v$session.
Your problem is you want to remain in the Stone Age, where the CD rom didn't exist and records where played by birds.

How do we find out how many concurrent users login at peak time?

Hi Frienz
PLease let me know if there is any database trigger that we can keep to monitor this?
Poonam Sachdeva

You can also use audit features of the database to audit user connections/disconnections
and write the query to get what you need.
Or you can also use with 9i/10g a LOGON/LOGOFF trigger to audit session connection and disconnection in a audit table and then write the query on this audit table to analyze the maximum number of connections.

What db-ressources are significant while runtime parsing queries in reports

I have long idle time in running a report
what db-ressources are significant
while running Report
Report compiling / Query parsing ?
i have running the same report from a AS 10g
in identical schema's
on two different instances ( TEST and PROD )
on a R11_2 orcale-db
in TEST-Instance the report does run well in some seconds
in PROD-Instance the report need more then 10 min
to analyze it I have trace_all on AS
and taken outputs in all triggers in the report
I can see,
the idle-time in the long-time report is between
the AFTER_PARAM_FORM - Trigger
and
the BEFORE_REPORT - Trigger
trace detail:
[2011/6/22 0:9:25:115] State 56016 (JobManager:updateJobStatus): Job 76089 status is: Bericht Before-Report-Trigger wird ausgeführt wird
ausgeführt
[2011/6/22 0:9:25:115] Debug 50103 (JobManager:updateJobStatus): Finished updating job: 76089
idle Time
[2011/6/22 0:20:17:459] State 56016 (JobManager:updateJobStatus): Job 76089 status is: Bericht Seite 1 wird formatiert wird ausgeführt
[2011/6/22 0:20:17:459] Debug 50103 (JobManager:updateJobStatus): Finished updating job: 76089
this is while
Report is "compiled".
Queries are parsed.
because both the reports run on the same AS
and both schemas are identical
it maybe the differences come from different the instance-system-ressources
( in the TEST-Instance there is 1 or 2 users / sessions,
in the PROD-Instance there are > 100 users / sessions )
what db-ressources are significant for performance
while running Report
Report compiling / Query parsing ?
what other reason may be for the idle-time in this report ?

In your trace your idle time is between Before Report Trigger and the formatting of page 1. So, the activity is in the database.
Report compiling / Query parsing ?Compilation has already taken place when the report runs, so that's not it.
Parsing depends on the query. If the query exists in the SGA it shouldn't parse again. However, if you have lexical parameters the query may be different each time. Still, parsing is (never) a problem.
What remains: execution of the query. Trace the report session in the database.
I just use TOAD for monitoring a session and see which query is executing for a particular session.

Database level triggers

How to know whether any of following database level triggers are enabled?
Database Startup Triggers
Logon/Logoff trigger
DDL triggers
Thanks

select owner, trigger_name, status from all_triggers;It should tell you its status!

Problem with create context.

I have one database instance in which I run the following command using DBUser1.
------------------------START---------------------------------
create or replace context MyContext using set_context_id;
create or replace procedure set_context_id
context_id in number
) as
begin
     dbms_session.set_context (
     'MyContext',
     'context_id',
     context_id
end;
--------------------------END-------------------------------
Now, I have another user DBUser2, and I want to be able to use the same context name "MyContext" for this user as well. Since a context is unique, how can I use this context from DBUser2 ? As such, DBUser2 does not know anything about DBUser1 (until it looks up some system tables).

Normally you sit the context for the user without their knowledge such as via a database logon event trigger. All contexts belong to user SYS and we place the associated package under an application Id. No users have execute on the package.
You should be able to grant the users execute privilege on the associated package if you want the users to explicitly set the context though I have never done this and do not have a system in front of me to test with.

Assigned wrong role to administrator account.

Hi all,
To be able creating a user account on the portal. I wanted to add one role SAP_BC_JSF_Communication into account SAPJSF, but added it into j2ee_admin and restart system by accident. What I got now is I cannot use j2ee_admin logon portal.
Here comes the questions:
1. When I used j2ee_amin logon system, there was no any error message. It must be somewhere store the message for error handling. Where is it and how am I going to reach it?
2. I checked the setting using J2EE engine visual administrator. Under server \ service \ security provider, I did not see this role attached to j2ee_admin on tab user management. If that's the case, why I cannot logon portal?
PS) My NetWeaver version is 2004s SPS10.
Any advice would be appreicated.

Hi Mike:
Thanks for your reply. Currently, even NWA I also can't logon. After trace defaultTrace.trc through Log Viewer. I found some error messages.
