Security :: Encryption Method (password Starts With 06)?
Aug 29, 2013
Our Audit Company has given us a recommendation:"Old DB Link encrypted Passwords: The password of the Oracle databases links are encrypted using DES (password starts with 05). This encryption methord is known and users can decrypt the passwords using a simple SQL query. Please recreate the database links to use the new encryption method (password starts with 06)."What does it mean and how can we perform this recommendation?

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.

Our client is having requirements that data should be encrypted through-out the process (from transaction level to backup level).
Requirements are as below -
1) Data should be encrypted and can be access only through application (through front end).
2) Even if pl/sql, sql installed, developer user cannot able to fetch data from database.
3) Even DBA, should not have access to fetch the data from the database.
4) Only assigned DBA, should fetch details from database (provided he/she should have details of database as well as application's user / password).
5) It should be restricted by ip and user details (such as ip of application server with user/password of user).
6) Changes should be purely done from database level only.

We have got a new requirement wherein, The customer wanted the DBA Vendor (US) NOT to access the confidential information (ALL Columns) in the DB tables of PRODUCTION database. This is for few applications to comply with with export control rules. The thin support by Customer DBA will be allowed to access the Data, if required .
1) Web Based Interface ?.
2) DB Encryption (But if we encrypt ALL columns Serious performance issue expected, File level will not restrict DB level access)
3) Special setting on DB (DBA to do only backup and restoration related work only - But cannot access data)
4) Standard Tools / Utilities / Others ??.
Technologies are Oracle ,SQL

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.

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.

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?

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".
