We have a production database on 11.2.0.2 version. The application user was prompted to change the password after his password expired.

After changing the password he is not able to logon. The aud$ table does not show any occurrence of 1017, therefore it is not a question of Invalid password.
LVV> show parameter SEC_CASE_SENSITIVE_LOGON

Due to invalid password the user was locked. Can we track who hit the database with the wrong password?

OBJECTIVE: To allow a user to change their own password after logging into an application.
BACKGROUND: I have a stored procedure where I pass the userid, old password, and new password. The stored procedure contains the following ALTER statement:
EXECUTE IMMEDIATE 'ALTER USER :uid
IDENTIFIED BY :npwd REPLACE :opwd'
USING IN v_user_id, v_new_pwd, v_old_pwd;
where v_user_id, v_new_pwd, and v_old_pwd are the arguments passed to the stored procedure.
FACTS:
(1) The procedure compiles fine;
(2) During execution, SQLCODE returns "0" (i.e. zero);
(3) My userid does have permission to change my password and execute the stored procedure;
(4) At the time I call the stored procedure, I am successfully logged into the application with my userid and old password.
PROBLEM: When I try to login with the new password I get the following error: "ORA-01017 invalid username/password; logon denied".

One of my Customer had followed the document applied pertaining to mitigate against vulnerability CVE-2012-3132.
New Document Mitigation steps for CVE-2012-3132 [ID 1482694.1]
This was applied to a database and it stopped the 'password' command from succeeding in SQLPLUS. Once the trigger was disabled, it worked fine.
ORA-00604: error occurred at recursive SQL level 1
ORA-06531: Reference to uninitialized collection
ORA-06512: at "SYS.NAME_SECURITY", line 165
ORA-06512: at line 2
Why is this behavior seen? By the way, he was able to change the password using TOAD. Only sqlplus is the issue.

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.

We are trying to implement the following security to our database.
As of now, the access rights are same for all the windows users logging into the Oracle application with the same Oracle user Id.
But now, we want to improve our security by granting different levels of rights to the users based on their Network Id even though they use the same Oracle User Id to log into the application.
We are not looking for the users to be identified externally.
(CREATE USER "OPS$ORACLE-BASE.COMTIM_HALL" IDENTIFIED EXTERNALLY;
GRANT CONNECT TO "OPS$ORACLE-BASE.COMTIM_HALL";
)

I'm working for a credit card company and on a security project. We have oracle databases. Currently the passwords have to be changed every so often for key accounts for security purposes. Any tool to automate the process?
Any way to automate password changes on many accounts where only some people would be able to get the new password once it was changed.
Also, these IDs/passwords are sometimes used by applications to connect to the database so .ini files or some type of connection file would need to be changed automatically also.

for e.g.
1. to put the file with password in another folder where the user (monitor) has no access to see the file.

We have a requirement that the password of users never expire. But the user is notified when the password has not been changed for a long time. For example: If the user has not changed his password in 100days, he is to be notified that the password is old and he should consider changing it.
Is this possible directly through the password policy configurations? Or will it have to be handled using a separate procedure?

While searching for password encryption I came across these statements.
1.Password Encryption While Connecting. This protection is always in force, by default. Passwords are always automatically and transparently encrypted during network (client/server and server/server) connections, using a modified DES (Data Encryption Standard) or 3DES algorithm, before sending them across the network.
Confirm whether by default oracle encrypts the password before sending it to the database across the network even when the clear text password is used for connecting from a jdbc client.

I have a database in which a user xxxx is assigned a password 'bbbbb'.I want to change the password to the one which was used before which was 'aaaaa'.But when I change the password it was saying "Password cannot be Reused".So I checked in user profile and found out that password_reuse_time=unlimited and password_reuse_max=5.
So what I did was change the password 6 times to something else(Since it is 5) and then tried changing it to 'aaaaa' but still it is saying "Old password cannot be reused".
