Oracle Audit Vault 10.2.3.2 & Linux Red Hat 5 on a V.M. box
I'm new to the Audit Vault and am experiencing some issues. Right now my biggest question is how does A.V. deal with TNS issues (allowing the collectors to find remote target db's) when we do not add any tns entries to the local tnsnames file?
We've recently added more space and our sysadmins have moved all of our AV data to the new disk space and have supposedly updated pointers allowing us to continue seamlessly. However now my collectors won't start, they are complaining with message below. These had started previously before the space add.

AVDF current version 12.1 not support External/SAN storage. my question is, if customer get a huge number of Audit log and DBFW event records, then how max size can Audi Vault server support for online data (not archive data)? and can I use a Hardware server with multiple HDDs for AV Server?
Does installation of oracle label security and data vault causes overhead? How about after installation and then register with database. How much overhead?
Note that I don't want to use it for now. Then what are the reasons for registering with oracle database?
I am trying to setup logon/logoff auditing for our databases which reside in 9i and 10G on sun solaris servers. I am asked to turn on auditing sending the audit data to syslog! How exactly do you do that?
Let us say I want to audit data updates, deletes on existing table EMP_TAB that has a few hundred thousands of records.I created a shadow table Emp_tab_audit and added few audit columns
Emp_tab ( Empno NUMBER NOT NULL, Ename VARCHAR2(10), Job VARCHAR2(9),
[code]...
I am mostly interested in UPDATES and DELETES but I decided to add INSERTS to have full history for each eomplyee in one table (audit schema) instead of querying two tables all the time (production table and audit table) to see the changes.
I created this AFTER INSERT, UPDATE, DELETE trigger.decided to copy the :NEW values for INSERT and UPDATE and :OLD values for DELETE. attached.
so when insert happens, the first audit row is created in EMP_TAB_AUDIT. update happens, the 2nd new row is created in EMP_TAB_AUDIT.
The problem I am facing is the old records that curently exist. If someone updates an old row I am copying the :NEW values so I won't have a copy of the :OLD values unless I create 2 ROWS (one for the old and one for the new).
Do you think I should copy all the hundreds of thousands of records to the AUDIT tables for this to work.
******************************************************************* CREATE OR REPLACE TRIGGER TRG_EMP_AUDIT AFTER INSERT OR DELETE OR UPDATE ON EMP_TAB FOR EACH ROW DECLARE v_operation VARCHAR2(10) := NULL;
getting logon timestamp for our auditing process. In some website, it says to get the logon timestamp I have to select it from timestamp column of dba_audit_session but when I do this, some results has a logoff earlier than logon. Is timestamp column really the logon timestamp?
In Oracle Database 11.2.0.2, to delete audit trails after the audit records have been inserted into Oracle Audit Vault, is it necessary to schedule Oracle Audit Vault jobs to clean up audit trails on a scheduled basis, or AV automatically cleans up audit trails after the audit records have been inserted into the Audit Vault? I know there is a DBMS_AUDIT_MGMT package, but in 11gR2, the deletion of audit trails isn't done automatically?
i want to trace user activities, I want to generate the file with SQL statement generated by particular user. I tried to look in to sys.AUD$ but all i get is logging logout and locations but no SQL Text.
I am using 'Novell Sentinel Log Manager' to collect/fetch logs from my Oracle 11g R2.To enable auditing, first I did following:
login as sys, then SQL> create user testuser identified by "testuser"; SQL> grant connect to testuser SQL> grant dba to sharf SQL> grant CREATE SESSION to testuser; SQL> grant select on v_$session to testuser; SQL> grant select on v_$version to testuser; SQL> grant select on SYS.DBA_AUDIT_TRAIL to testuser; SQL> grant select_catalog_role to testuser; SQL> grant select any dictionary to testuser;
Now logon/logof of user 'testuser' are logged , as well as if testuser drops a table or creates a table, its also logged . but when 'testuser' insert a new record, this information does not logged ;( while I need to know exactly what was added SQL> insert into emp (empid, name, salary) values (10002, 'Ron', 6000)
likewise if 'testuser' modify/update an existing record it also does not logged. SQL> update emp set salary=700 where empid=10001;
which sql statements I have to execute to start auditing 'insert' and 'update', so that I know what was added/inserted and exactly what was updated/ changed/modify by user 'testuser'.
I installed Audit Vault Server 12 (not install firewall) in a oracle linux vmware and activated an agent for Oracle 11g release 2 in windows 7 x64 vmware according to Oracle® Audit Vault and Database Firewall Installation Guide and Administrator’s Guide Release 12.1.0 as follows:
1) ALTER SYSTEM SET AUDIT_TRAIL=XML, EXTENDED SCOPE=SPFILE; Database restart
2) Register the Oracle Database Host Machine
3) Deploy Agent and Request Activation on the Host Machine
4) Create user accounts on the secured targets and set up Oracle AVDF user privileges on an Oracle Database secured target.
5) Register Secured Targets in the Audit Vault Server with user acount of stpe 4:jdbc:oracle:thin:@//IP:1521/orcl
6) Configure an Audit Trail in the Audit Vault Server : TABLE - sys.aud$ or DVSYS.audit_trail$, DIRECTORY - directory of audit trail xml saved.
I turned off firewall just in case.Administrator web page of AVDF showed only messages of "request completed" after configuring an audit trail in the Audit Vault Server.But, collection state was a red downward arrow, and even auditor web page showed same state.I couldn't show audit trails in the auditor web page.
I have to find all the 'failed log ins' through audit report. then it has to be uploaded to a table. The script, either in windows or unix should be reusable and can read files one by one.
I want to audit user connection on my reporting database, and send a report to application team on monthly basis, with a list of users who are not connected for a month and remove them.
What would be best method, i know there is LOGON trigger, or database level auditing.
in my environmnet audit is working audit_trail=db,extended . i am also viewing report of audit trail from dba_audit_trail or aud$. But problem is that i have to generate report on which object of schema what audit is running .
or from which tables we can get information of following commands.
AUDIT ALL BY xx_test BY ACCESS; AUDIT SELECT TABLE, UPDATE TABLE, INSERT TABLE, DELETE TABLE BY xx_test BY ACCESS; AUDIT EXECUTE PROCEDURE BY xx_test BY ACCESS;
Lost Windows password? Forgot Windows password? Your PC was hacked? Therefore, it is a basic step for every Windows users to enhance the security of Windows password. In the networks, it is found that a number of user's passwords are easy to guess. Only the smallest groups are the most security conscious and select passwords that are mixed lowercase and uppercase letters, numbers and punctuation to create cryptic passwords. Adopting strong password is one of the most effective ways to ensure system security. Here are several methods for you to enhance the security of your passwords in Windows 7/2000/XP/Vista and so on. You'd better remember the methods below unless you want to reset Windows password from time to time.
1. Is random password a great password?
A common myth is that totally random passwords like Ht3&e#L%5d@$B are the best passwords. This is not true. While they may be strong passwords, they are usually difficult to remember, slow to type, and sometimes vulnerable to attacks against the password generating algorithm. It is easy to create passwords that are strong but much easier to remember by using a few simple techniques. For example, consider the password "Luck-73@Better?". This password utilizes uppercase and lowercase letters, two numbers, and three symbols. The password is 15 characters long and can be memorized with very little effort. Moreover, this password can be typed very fast. The portion"Luck" and "Better" alternate between left and right-handed keys on the keyboard, improving speed, decreasing typos, and decreasing the chances of someone being able to discover your password by watching you.
2. Create the long Windows password
Although a password may eventually be discovered through some means, it is possible to create a password that cannot be cracked in any reasonable time. If a password is long enough, it will take so long or require so much processing power to crack it. That is essentially the same as being unbreakable (at least for most hackers).
3. Create the Windows password constantly?
This may be good advice for some high-risk passwords, but it is not the best policy for every user. It is frustrating for a user to have to constantly think of and remember new passwords every 30 days. It may be better to focus on stronger passwords and better user awareness rather than limiting password age. A more realistic time for the common user may be 90-120 days.
4. Write down Windows password in a proper place
Sometimes it is necessary for some users losing and forgetting complex passwords easily to write down them somewhere proper. However, it is important to educate users on how to write down passwords properly. Obviously, a sticky note on the monitor is not a good idea, but storing passwords in a safe or even a locked cabinet may be sufficient.
5. 14 characters is the optimal password length
Each character that you add to your password increases the protection. Your passwords should be 8 or more characters in length; 14 characters or longer is the Optimal Password Length. Many systems also support use of the space bar in passwords, so you can create a phrase made of many words. It is not easier to forget and lose, as well as longer than a simple password, and harder to guess.
6. Try not to use the same Windows password for all accounts
Some users always make the same passwords for every account to make it easy to remember. In that case, when any one of them lost, your other information protected by that password will be in danger as well. It is serious to use different passwords for different systems and accounts.
7. Do not use some common words that other users maybe guess
Most of users prefer to use some common words to remember easily, for example, login name, birth date, driver's license, passport number, pets' name and other words contained their personal information someone knows. In that case, your Windows system will not be safe anymore. Moreover, do remember not to use some words spelled backwards, abbreviations, sequences or repeated characters and adjacent letters, such as, asdfgh, 123456, 888888, abcdef and so on.
You can smoothly use your Windows now because the strong and powerful Windows password is created successfully, Certainly, I believe that many users lost Windows password and forgot Windows password, then you need have to reset Windows password or recover Windows password. It is a big problem for plenty of Windows users that how to reset Windows password. how to recover Windows password and they are puzzled by resetting windows password, for instance, reset Windows 7 password, recover password Windows XP, remove Windows Vista password and other operating systems after they create the password with complex letters, numbers and symbols. However, it is unnecessary to worry and it is said that things will eventually sort themselves out. There are many ways to reset forgotten Windows password, including use windows password reset disk and windows password reset software, like Super Windows Password Reset, a professional windows password reset software which could enable you to logon to Windows smoothly without reinstalling system.
In Sybase, my application was using system tables to perform application login security. Those tables obviously don't exist in Oracle. I am looking for ways to provide the following functionality in an Oracle world:
1. How to determine 'x' days of inactivity based on "last login date"?
2. How to determine when a new user logs in for the first time and force them to change their password?
3. If we need to reset a users password, how can we require the user to change their password?
4. Is there any other option other than storing a user-id/password in the application code for locking a user's account if their account needs to be locked due to inactivity?
5. In the USER_USERS view there is a status column. What the different status's can be?
Provide me the script which would track all the users security violations like ... say for example i want to find which users logged in and what he did in database prospective.
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.
We can audit a particular table alone, I would like to audit one table, to find all different kinds of queries fired (Including select, insert and update) over a period of 2 months.
I have to create a audit/history table on a master table so that I can store the old/current state of data in my audit table. I am planning to write following program.
1. Created the audit table with similar number of records. 2. Everyday at a particular time I will compare the audit/main table and push the records in audit table which are either updated or not present in the audit table so that the audit table = main table + old state of data.
I am unable to figure out the proper way to implement the point 2 above in oracle database.
