Local policies to secure managed passwords

&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; Windows 19803.html "Local Security Policy" with >XP system is a good system security management tool.

It can be said that any computer may have security risks, these security risks will often cause important information leaks. As a user, there is an obligation and responsibility to ensure the safety of the computer.

When it comes to safety, many people think that it is the right of the Masters, only the master can complete the unfathomable things. In fact, Microsoft in order to improve the security of the system to meet the needs of users in the security of the computer to provide us with a local Security policy configuration window, today we will introduce you to the security settings in the password policy.

Tip: We can go to the Control Panel, open the Administrative Tools item, double-click Local Security policy to open the Local Security Settings window, and select Password policy under Account policy on the left side of the window (Figure 1).

Password must meet complexity requirements

Getting the login password is one of the most basic tactics hackers can attack, so we start by defending the password. Since many users set passwords using simple numbers or letters, some do not even use a password, which is extremely unsafe. In this respect, it starling Network (http://www.it8g.com) to remind you only need to double-click the password must meet complexity requirements, in the open window to set it to Enabled.

Minimum password length

Too short passwords can easily be violently cracked, so the password must be set long enough for the user to always forget this. In this case, we can double-click to open the minimum password length and set its value to 6, so that fewer than 6 digits are set for the password (Figure 2).

Maximum password/short lifetime

Theoretically, no matter how complicated the password is, only a long enough time can be violently cracked. This shows that our long-term use of a password is extremely unsafe, we have to double-click to open the "Maximum password Lifetime", set a time, such as 30 days, so that after 30 days, will automatically remind users to modify the password.

Correspondingly, there is a "minimum password lifetime", which indicates how long the user must use the password to continue changing the password, for example, by setting it to 10 days, so that it can be modified only if the current password time is 10 days. Doing so will prevent some hackers from directly modifying the account password.

Iv. Mandatory password history

After you set the maximum password lifetime, you face another problem, which is that you need to reset a password every time you expire. But some users are lazy, often using only two or three commonly used passwords for recycling, which is also unsafe for the security of the system. In this case, we just double click on the "Enforce password history" item, collars it to remember the larger password history, so you can prevent users in a short period of time to reuse the same password content.

After this setting, when the user then sets the password, must conform to the configured policy, otherwise will pop-up error window, prompts the password does not satisfy the password policy request (Figure 3), this forces the user to set long enough complex password, provides the system security protection.
