View 3 Replies View RelatedLost 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?

One of our auditing recommendation is to move table AUD$ to a separate tablespace from system. Why this recommendation is important and how to do this action ?
View 2 Replies View RelatedWe have recently upgraded our DR environment from 9i to 11g. We have auditing turned on for 3 tables.

Here are some background facts in order to save time regarding actions already taken:
(1) The userid used to login successfully is the same one passed to the above SQL;

I've a problem in that I cannot log onto one of our schemas on one of our databases via SQL*Plus, TOAD, SQL Developer etc.. Attempting to do so yields the following error message: "ORA-01017: invalid username/password; logon denied"
However, if I try to log onto the same schema via any of the unix boxes using the sqlplus command, that works fine.
It's only this schema that is affected. For all other schemas (on that database and on others), I don't have this problem.
what the DBAs have done?
while testing SYS remote connection in our staging server. Executing the command below is OK:
sqlplus sys/<password>@sales as sysdba
While this is mind-boggling for me...
sqlplus sys@sales as sysdba
Enter password:

Enter user-name:

How to disable a user's sql login? To ellaborate, I want a user to login through a certain application only with his userid on database level & not through "sqlplus username@dbname".
Is it possible? If no, then what can be done to achieve below.
I have a userid which has all the update, delete privileges on it. That id needs to be configured in the application alongwith the password. So in order to avoid misuse of that id I want to block its sql access.
I am not sure whether this can be achieved or not.
