Four magic weapons escort Win 7 security

The following are some of the very useful features that Windows 7 brings to us in terms of security. I believe that with it, we can use computers more safely, and everyone is concerned about the security of the system. Windows 7 has made a big change in security compared to the previous system. Here I will take everyone to experience the security performance of Windows 7.

First, the parental control function

In Windows 7, there is a parental control function, through which parents can control the child's use of the computer, such as using a computer Time, what kind of games can be played with the computer, which applications can be run, which programs can not be run, can be personalized, to ensure that children use the computer safely and reasonably, the following methods:

Create a first The standard account can be set without a password for the child to use, and then set a password for the administrator account to prevent the child from using it. Open the “User Account and Family Safety” button in the control panel, select “Parental Control”, select just now. Create a good user, you can set the parental control for the user, as shown in Figure 3, select “ enable, apply the current settings & rdquo;, then set “ time limit & rdquo;, you can set any time of the week can be any day Let your child use the computer, control the time period when the child is using the computer, set the level of the game the child can play, and block Given game.

In addition, you can also set the "Allow or block specific applications" option, the system will pop up a dialog box, you can set the program that the user can only allow, the system will automatically list the current computer installation. All applications, including some of the applications that come with the system installation, such as minesweepers, cards, etc., generally list all applications ending in EXE automatically. This can limit your child's use of certain applications, such as not allowing children to use QQ, not allowing programs that use improper operations to corrupt data.

Second, improved version of User Account Control ( UAC )

User Account Control ( UAC ), in fact, many people are no strangers, there is a Windows Vista However, it has been criticized for a long time. As long as the user changes the computer system slightly, it will pop up a dialog box to seek permission from the user and the screen will be darkened. This way, the security of the system is improved, and the virus and the virus are effectively prevented. Trojans damage the system, but at the same time make users feel very cumbersome, so it has become one of the most hated features in Windows Vista.

In Windows 7, the user is asked to choose the UAC notification level. The biggest improvement in User Account Control (UAC) is that the control panel provides more control options, and the user can select the appropriate UAC according to their needs. level.

Go to the Control Panel's "System and Security" and click on "Change User Account Control Settings" in the "Operation Center". The UAC settings under Windows 7 provide a slider to allow Users can set the level of notifications, you can choose 4 levels, you can personalize the choice according to personal preferences, eliminating the harassment of the old pop-up prompts.

Third, Windows BitLocker Drive Encryption, File Security

Windows BitLocker Drive Encryption is a new security feature that prevents unauthorized users from accessing the drive. All files, this function can better protect the security of the data in the computer by encrypting all the data stored on the Windows operating system volume. This function is very useful for both individual users and enterprise users. Open the control panel. "System and Security", select "BitLocker Drive Encryption", select the drive letter to be encrypted, click "Enable BitLocker", and then prompt the drive is being initialized, then set the drive encryption password, as shown in Figure 4. , click “Next”, in order to prevent forgetting the password, you can also set the BitLocker recovery key file, and finally click “ start encryption & rdquo; This way, if you want to access the disk drive, you will need to enter a password.

Four, powerful Windows Firewall

Windows 7 previous systems generally have their own firewall, but the function is simple, generally regarded as chicken ribs, this time Windows 7 The built-in firewall has been greatly improved, and the function is relatively powerful. Open the "Security and System" in the Control Panel. You can see the Windows Firewall. Its biggest feature is internal and external defense, through the "home or work network" ; and "public network"; two aspects to protect the computer.

Especially in the "advanced settings", the functions are more comprehensive, comparable to the general professional firewall software, through the inbound and outbound rules can set the application to access the network, and the monitoring function can clearly reflect The current network circulation situation, as shown in Figure 2, can also set custom inbound and outbound rules. I believe that the Windows 7 firewall will have more users to use.
