Security :: Encrypt Column In Table (TDE) With 160 Rows
Jun 12, 2012
I need encrypt column in the table (TDE) with 160 rows (PK) i'd like know what impact if i rn in time production this procedure. And as will be behavior the oracle database if this column is FK.
I have a password column in my table which i need to encrypt coz of the simple fact that anybody who queries should not be able to see the password which is a kind of violation.
We currently hardcode the password inside our Java application to make the connection with the Database,this makes the password to be visible to all users who can read the application code. How can we encrypt the database password so we don't have to hardcode it into the application?

See attachment for table creation and table data.
The table tbl_completed has two columns, id and completed. I have created a query that does provide me with the result set that I need, but I need to pivot the rows into columns. So instead of a result set to look like this:
select completed, count(completed) as theCount from tbl_completed group by completed;
COMPLETED THECOUNT Y 772 N 720
I need a result set to look like this:
COMPLETED,Y,N THECOUNT,772,720
The best solution that I have discovered is this, but I figuring their might be a better way.
select (select 'THECOUNT' from dual) as COMPLETED, (select count(completed) from tbl_completed where completed = 'Y') as Y, (select count(completed) from tbl_completed where completed = 'N') as N from dual;
I want my query to return the rows of the table where a column contains a specific values first in a certain order, and then return the rest of the rows alphabetized.
For Example:
Country ALBANIA ARGENTINA AUSTRALIA .... CANADA .... USA ....
Now i want USA and CANADA on top in that order and then other in alphabetized order.
trying to update a column in a table which has 3 columns of 16million rows from column in another table which has 1million rows, there is no relationship between the 2 tables.
Table A has 3 columns of 16million rows, the first two columns have 16million ID numbers, the 3rd colunm is currently NULL.
Table B has 1million Numbers, i need to somehow update column 3 in table A using the numbers in table B, it doesnt how many times each of the 1 million numbers are used but i dont want it to just update every row to the same value.
how can we mask value of some columns in table? For example: user A is supervisor, he can query salary column in employee table, but for user B, he is staff member, he can query salary column but system just shows ***** or something like that for salary value.
My boss make a requirement in exist database as some user can view salary column at employment table by SQL and some user can view salary column at employment table by SQL.
The boss do not like to make changes front SQL. Ooracle 11g vault or Oracle Label Security is best for this requirement? my oS is 2008 32 bit window and DB is 11.2.0.1
I'm writing a VPD function to be used for column masking. The predicate (WHERE-clause) it generates may take many different forms. In particular, it may contain inner-selects; for example,
"exists(select '*' from B where B.VAL = '123' and A.KEY = B.KEY)"
where A is the table that is associated to the VPD function, and B is some other table.
if this is OK for column masking? If not, my VPD function may sometimes work and sometimes fail, in unexpected ways.
The Oracle Database Security Guide (11g Release 1) says
Column-masking conditions generated by the policy function must be simple Boolean expressions, unlike regular Oracle Virtual Private Database predicates".
This seems to indicate that there are cases where a VPD function works for row-level security, but not for column masking.
an example of a 'regular Oracle VPD predicate' that doesn't work for column-masking?
I'm running a 10.2.0.4 database with auditing enabled:
SQL> show parameter audit_trail;
NAME TYPE VALUE ------------------------------------ -------- ------------- audit_trail string DB, EXTENDED
I have auditing enabled for create session:
SQL> select audit_option, success, failure from dba_stmt_audit_opts;
AUDIT_OPTION SUCCESS FAILURE ---------------------------------------- ---------- ---------- CREATE SESSION BY ACCESS BY ACCESS
My problem is that when I run a report against DBA_AUDIT_SESSION, the CLIENT_ID column is never populated, it's always blank. I've tried running a trigger to populate the client_identifier variable:
create or replace procedure capture_module as begin dbms_session.set_identifier(sys_context('userenv','module')); end; / [code]....
And if I put an access trigger on a table and create an audit event, the CLIENT_ID column from DBA_AUDIT_TRAIL and DBA_COMMON_AUDIT_TRAIL both show the updated value (module), but no matter what, I never get the CLIENT_ID column in DBA_AUDIT_SESSION to show anything - it's always null.
I want to run a report against DBA_AUDIT_SESSION that will tell me who logged in, when they logged in and out, where they logged in from and the one thing I can't get - what module they were running (SQLplus, Toad, etc). Why can't I get the CLIENT_ ID column to take the value I'm setting with the logon trigger?
I want to understand the restrictions that apply to VPD functions when used for column masking, compared with their use for Row-Level Security. According to the Oracle Database Security Guide (11g Release 1) Column-masking conditions generated by the policy function must be simple Boolean expressions, unlike regular Oracle Virtual Private Database predicates.
I have long understood the above as implying that column-masking conditions should not contain sub-queries (i.e. inner selects). However, we tested using a condition with a select inside another select (2-level nesting) and yet it worked. We were on 11g Release 2, by the way. So, I wonder about using sub-queries in column-masking conditions? Or, alternatively, what Oracle means with "regular VPD predicates" and "simple Boolean expressions" (of course, in the context of VPD)?
We are using oracle forms 6i as front end and oracle 10g as back end.When we are creating a new user, the password should be stored in back end table in encrypted format.
i have IR report page and download column as blob,how can security applied in specific column wise?e.g. Report page have more rows, and applied query in condition.
Select ID,dbms_lob.getlength(Blob_file) Download from Document_master where Created_by=UPPER(:APP_USER) OR (exists (select '' from apex_workspace_group_users awgu where awgu.user_name =:app_user AND awgu.GROUP_NAME='EMPLOYEE_GROUP' ) )
Now all the rows with Download column to see EMPLOYEE_GROUP users,but i need control the download column only except Created_by=UPPER(:APP_USER) ,this case how can do the security.
I have a script that creates all db links for a schema. The script currently has hardcoded password use to create db link. We do not want to hardcoded password in the script.
I am planning to manually ask to input the password using accept command in sqlplus but this may be time consuming because there are many db links. So, I wanted to know if there are any better options ? Is there any way to use encrypted password in the sql file?

There are millions of DISTINCT ID values in TABLE_1 and corresponding to each ID there are some values for all the days of a month. I need to insert these values in TABLE_2 in the above format.
